I don't have a great deal of experience with TFS, other than using it for source control. I am working on a C# application that will need to modify files that are being controlled by TFS. From within my C# application, how can I check out a file that is controlled via TFS?
Thanks - Randy
You can use PendEdit to make your files writables, make your changes to it, then you add it to the pending changes, and finally check it in.
Here is some code where a folder structure is created and then checked in (Very similar to what you will need).
private static void CreateNodes(ItemCollection nodes)
{
using (var tfs = TeamFoundationServerFactory.GetServer("http://tfsserver:8080"))
{
var versionControlServer = tfs.GetService(typeof (VersionControlServer)) as VersionControlServer;
versionControlServer.NonFatalError += OnNonFatalError;
// Create a new workspace for the currently authenticated user.
var workspace = versionControlServer.CreateWorkspace("Temporary Workspace", versionControlServer.AuthenticatedUser);
try
{
// Check if a mapping already exists.
var workingFolder = new WorkingFolder("$/testagile", #"c:\tempFolder");
// Create the mapping (if it exists already, it just overides it, that is fine).
workspace.CreateMapping(workingFolder);
// Go through the folder structure defined and create it locally, then check in the changes.
CreateFolderStructure(workspace, nodes, workingFolder.LocalItem);
// Check in the changes made.
workspace.CheckIn(workspace.GetPendingChanges(), "This is my comment");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
// Cleanup the workspace.
workspace.Delete();
// Remove the temp folder used.
Directory.Delete("tempFolder", true);
}
}
}
private static void CreateFolderStructure(Workspace workspace, ItemCollection nodes, string initialPath)
{
foreach (RadTreeViewItem node in nodes)
{
var newFolderPath = initialPath + #"\" + node.Header;
Directory.CreateDirectory(newFolderPath);
workspace.PendAdd(newFolderPath);
if (node.HasItems)
{
CreateFolderStructure(workspace, node.Items, newFolderPath);
}
}
}
Using the other solution gave me permission problems.
Here's an alternative way to checkout your files using tf.exe:
//Checkout file
Process proc = new Process();
proc.StartInfo =
new ProcessStartInfo(
#"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\tf.exe",
string.Format("checkout \"{0}\"", fileLocation)
);
proc.StartInfo.UseShellExecute = false;
proc.Start();
proc.WaitForExit();
For those looking to use the first solution and resolve the permission issue you can use the following code to use the current credentials, this replaces the "TeamFoundationServerFactory.GetServer" call then use the TfsTeamProjectCollection (tmPrjColl) to get the VersionControlServer:
using Microsoft.TeamFoundation.Client;
using MTVC = Microsoft.TeamFoundation.VersionControl.Client;
using MVSC = Microsoft.VisualStudio.Services.Common;
MVSC.VssCredentials creds = new MVSC.VssCredentials(new MVSC.WindowsCredential(true));
using (TfsTeamProjectCollection tmPrjColl = new TfsTeamProjectCollection(new Uri("<source control URL>"), creds))
{
MTVC.VersionControlServer verCtrlSvr = tmPrjColl.GetService<MTVC.VersionControlServer>();
...
}

Normally we can move the directory using
// source is: "C:\Songs\Elvis my Man"
// newLocation is: "C:\Songs\Elvis"
try
{
// Previous command was: Directory.Move(source, newLocation);
DirectoryInfo dir = new DirectoryInfo(source);
dir.MoveTo(newLocation);
}
catch (Exception e)
{
Console.WriteLine("Error: "+ e.Message);
}
Now, when using the azure:
string myconnectionString = ConfigurationManager.ConnectionStrings["StorageConnection"].ConnectionString.ToString();
string myshareName = "Mysampleshare";
string mydirName = "Mysampledir";
// Get a reference to a share and then create it
ShareClient myshare = new ShareClient(myconnectionString, myshareName);
ShareDirectoryClient directory1 = myshare.GetDirectoryClient(mydirName);
string myshareName2 = "Mysampleshare2";
string mydirName2 = "Mysampledir2";
// Get a reference to a share and then create it
ShareClient myshare2 = new ShareClient(myconnectionString, myshareName2);
ShareDirectoryClient directory2 = myshare2.GetDirectoryClient(mydirName2);
Directory.Move(directory1.Path, directory2.Path);
I am unable to move the directory from one location to another using azure. I am getting exception.
DirectoryNotFoundException: The path specified by sourceDirName is invalid
Please suggest your advice.
ShareDirectoryClient essentially implements Azure File Service REST API thus you cannot use System.IO operations like Directory.Move with it.
There are two possible solutions:
If you want to use the SDK, what you will need to do is list files and directories recursively in the source directory and then copy individual files from source directory to target directory. You will also need to create directories in the target directory as well. Once the copy operation is complete, then you will need to delete all files and directories from the source directory. Once the source directory is empty, only then you will be able to delete the source directory.
You will need to do all this because the REST API does not natively support move operation. To accomplish move, you will need to perform copy operation followed by delete operation.
If you want to use System.IO, then you will need to mount the file share as a shared network drive so that you can get a drive letter assigned to that file share. Once you have that, then you will be able to use operations like Directory.Move available in System.IO namespace.
UPDATE
Please try the code below:
using System;
using System.Threading.Tasks;
using Azure.Storage.Files.Shares;

{
class Program
{
const string MyconnectionString = "DefaultEndpointsProtocol=https;AccountName=account-name;AccountKey=account-key";

ShareDirectoryClient sourceDirectoryClient = myshare.GetDirectoryClient(SourceDirectoryName);
ShareDirectoryClient targetDirectoryClient = myshare.GetDirectoryClient(RenamedDirectoryName);
await RenameDirectory(sourceDirectoryClient, targetDirectoryClient);
Console.WriteLine("Directory renamed.");
}
static async Task RenameDirectory(ShareDirectoryClient sourceDirectoryClient,
ShareDirectoryClient targetDirectoryClient)
{
//Create target directory
await targetDirectoryClient.CreateIfNotExistsAsync();
//List files and folders from the source directory
var result = sourceDirectoryClient.GetFilesAndDirectoriesAsync();
await foreach (var items in result.AsPages())
{
foreach (var item in items.Values)
{
if (item.IsDirectory)
{
//If item is directory, then get the child items in that directory recursively.
await RenameDirectory(sourceDirectoryClient.GetSubdirectoryClient(item.Name),
targetDirectoryClient.GetSubdirectoryClient(item.Name));
}
else
{
//If item is file, then copy the file and then delete it.
var sourceFileClient = sourceDirectoryClient.GetFileClient(item.Name);
var targetFileClient = targetDirectoryClient.GetFileClient(item.Name);
await targetFileClient.StartCopyAsync(sourceFileClient.Uri);
await sourceFileClient.DeleteIfExistsAsync();
}
}
}
//Delete source directory.
await sourceDirectoryClient.DeleteIfExistsAsync();

I have FileSystem watcher for a local directory. It's working fine. I want same to implement for FTP. Is there any way I can achieve it? I have checked many solutions but it's not clear.
Logic: Want to get files from FTP later than some timestamp.
Problem faced: Getting all files from FTP and then filtering the result is hitting the performance (used FtpWebRequest).
Is there any right way to do this? (WinSCP is on hold. Cant use it now.)
FileSystemWatcher oFsWatcher = new FileSystemWatcher();
OFSWatchers.Add(oFsWatcher);
oFsWatcher.Path = sFilePath;
oFsWatcher.Filter = string.IsNullOrWhiteSpace(sFileFilter) ? "*.*" : sFileFilter;
oFsWatcher.NotifyFilter = NotifyFilters.FileName;
oFsWatcher.EnableRaisingEvents = true;
oFsWatcher.IncludeSubdirectories = bIncludeSubdirectories;
oFsWatcher.Created += new FileSystemEventHandler(OFsWatcher_Created);
You cannot use the FileSystemWatcher or any other way, because the FTP protocol does not have any API to notify a client about changes in the remote directory.
All you can do is to periodically iterate the remote tree and find changes.
It's actually rather easy to implement, if you use an FTP client library that supports recursive listing of a remote tree. Unfortunately, the built-in .NET FTP client, the FtpWebRequest does not. But for example with WinSCP .NET assembly, you can use the Session.EnumerateRemoteFiles method.
See the article Watching for changes in SFTP/FTP server:
// Setup session options
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Ftp,
HostName = "example.com",
UserName = "user",
Password = "password",
};
using (Session session = new Session())
{
// Connect
session.Open(sessionOptions);
List<string> prevFiles = null;
while (true)
{
// Collect file list
List<string> files =
session.EnumerateRemoteFiles(
"/remote/path", "*.*", EnumerationOptions.AllDirectories)
.Select(fileInfo => fileInfo.FullName)
.ToList();
if (prevFiles == null)
{
// In the first round, just print number of files found
Console.WriteLine("Found {0} files", files.Count);
}
else
{
// Then look for differences against the previous list
IEnumerable<string> added = files.Except(prevFiles);
if (added.Any())
{
Console.WriteLine("Added files:");
foreach (string path in added)
{
Console.WriteLine(path);
}
}
IEnumerable<string> removed = prevFiles.Except(files);
if (removed.Any())
{
Console.WriteLine("Removed files:");
foreach (string path in removed)
{
Console.WriteLine(path);
}
}
}
prevFiles = files;
Console.WriteLine("Sleeping 10s...");
Thread.Sleep(10000);
}
}
(I'm the author of WinSCP)
Though, if you actually want to just download the changes, it's a way easier. Just use the Session.SynchronizeDirectories in the loop.
while (true)
{
SynchronizationResult result =
session.SynchronizeDirectories(
SynchronizationMode.Local, "/remote/path", #"C:\local\path", true);
result.Check();
// You can inspect result.Downloads for a list for updated files
Console.WriteLine("Sleeping 10s...");
Thread.Sleep(10000);
}
This will update even modified files, not only new files.
Though using WinSCP .NET assembly from a web application might be problematic. If you do not want to use a 3rd party library, you have to do with limitations of the FtpWebRequest. For an example how to recursively list a remote directory tree with the FtpWebRequest, see my answer to List names of files in FTP directory and its subdirectories.
You have edited your question to say that you have performance problems with the solutions I've suggested. Though you have already asked a new question that covers this:
Get FTP file details based on datetime in C#
Unless you have access to the OS which hosts the service; it will be a bit harder.
FileSystemWatcher places a hook on the filesystem, which will notify your application as soon as something happened.
FTP command specifications does not have such a hook. Besides that it's always initiated by the client.
Therefor, to implement such logic you should periodical perform a NLST to list the FTP-directory contents and track the changes (or hashes, perhaps (MDTM)) yourself.

I have got an alternative solution to do my functionality.
Explanation:
I am downloading the files from FTP (Read permission reqd.) with same folder structure.
So everytime the job/service runs I can check into the physical path same file(Full Path) exists or not If not exists then it can be consider as a new file. And Ii can do some action for the same and download as well.
Its just an alternative solution.
Code Changes:
private static void GetFiles()
{
using (FtpClient conn = new FtpClient())
{
string ftpPath = "ftp://myftp/";
string downloadFileName = #"C:\temp\FTPTest\";
downloadFileName += "\\";
conn.Host = ftpPath;
//conn.Credentials = new NetworkCredential("ftptest", "ftptest");
conn.Connect();
//Get all directories
foreach (FtpListItem item in conn.GetListing(conn.GetWorkingDirectory(),
FtpListOption.Modify | FtpListOption.Recursive))
{
// if this is a file
if (item.Type == FtpFileSystemObjectType.File)
{
string localFilePath = downloadFileName + item.FullName;
//Only newly created files will be downloaded.
if (!File.Exists(localFilePath))
{
conn.DownloadFile(localFilePath, item.FullName);
//Do any action here.
Console.WriteLine(item.FullName);
}
}
}
}
}
We are using SharpSvn to add SolidWorks files programatically to SVN tortoise.
When file is open in SolidWorks, i want to add it to SVN by code without closing file.
I used code below
var SvnResult = new SvnResult();
var FullPath = SvnHelper.FileCombine(FileName);
try
{
var SvnArg = new SvnAddArgs();
SvnArg.Force = true;
SvnArg.Depth = SvnDepth.Infinity;
//
SvnClient.Add(FullPath, SvnArg);
SvnResult.Message = "Success.";
SvnResult.Status = true;
//
return SvnResult;
}
catch (SvnException exc)
{
SvnResult.Message = exc.Message;
SvnResult.Status = false;
return SvnResult;
}
and i get error like this :
The process cannot access the file because it is being used by another process.
How can i add it to SVN without closing file?
Regards,
We solved the problem. At first we used TortoiseSvn.exe command lines to add and commit the file but when we used to send commit command, svn Dialog form was raised. For solving this problem I install “Command Line Client Tools” from the svn setup. By installing this option you can find svn.exe under svn path “C:\Program Files\TortoiseSVN\bin”.
I add this path to Environment Variables and then use svn command lines to add and commit while file is open.
public SvnResult CommitFiles_BySVNCmd(string filePath)
{
var fullPath = SvnHelper.FileCombine(filePath);
var svnResult = new SvnResult();
try
{
// svn add command
var status = GetStatus(fullPath);
//
if (status.LocalContentStatus == SvnStatus.NotVersioned)
{
var argumentsAdd = $#"add {fullPath}";
ProcessStart(argumentsAdd);
}
// svn commit command
var argumentsCommit = $#"commit -m Commited_Automatically {fullPath}";
ProcessStart(argumentsCommit);
svnResult.Message = "Success
svnResult.Status = true;
return svnResult;
}
catch (SvnException se)
{
svnResult.Message = se.Message;
svnResult.Status = false;
return svnResult;
}
}
private void ProcessStart(string arguments)
{
var processInfo = new ProcessStartInfo("svn", arguments);
processInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
Process.Start(processInfo);
}
Best Regards,
So I'm having a problem with automating my code to check-in files to TFS, and it's been driving me up the wall! Here is my code:
string location = AppDomain.CurrentDomain.BaseDirectory;
TfsTeamProjectCollection baseUserTpcConnection = new TfsTeamProjectCollection(uriToTeamProjectCollection);
IIdentityManagementService ims = baseUserTpcConnection.GetService<IIdentityManagementService>();
TeamFoundationIdentity identity = ims.ReadIdentity(IdentitySearchFactor.AccountName, #"PROD1\JR", MembershipQuery.None, ReadIdentityOptions.None);
TfsTeamProjectCollection impersonatedTpcConnection = new TfsTeamProjectCollection(uriToTeamProjectCollection, identity.Descriptor);
VersionControlServer sourceControl = impersonatedTpcConnection.GetService<VersionControlServer>();
Workspace workspace = sourceControl.CreateWorkspace("MyTempWorkspace", sourceControl.AuthorizedUser);
String topDir = null;
try
{
Directory.CreateDirectory(location + "TFS");
String localDir = location + "TFS";
workspace.Map("$/Automation/", localDir);
workspace.Get();
destinationFile = Path.Combine(localDir, Name + ".xml");
string SeconddestinationFile = Path.Combine(localDir, Name + ".ial");
bool check = sourceControl.ServerItemExists(destinationFile, ItemType.Any);
PendingChange[] pendingChanges;
File.Move(sourceFile, destinationFile);
File.Copy(destinationFile, sourceFile, true);
File.Move(SecondsourceFile, SeconddestinationFile);
File.Copy(SeconddestinationFile, SecondsourceFile, true);
if (check == false)
{
workspace.PendAdd(localDir,true);
pendingChanges = workspace.GetPendingChanges();
workspace.CheckIn(pendingChanges, Comments);
}
else
{
workspace.PendEdit(destinationFile);
pendingChanges = workspace.GetPendingChanges();
workspace.CheckIn(pendingChanges, Comments);
}
and the problem is that whenever it's NEW files (PendEdit works correctly when the files already exist in TFS) that my code is attempting to check in, and it runs through this code:
if (check == false)
{
workspace.PendAdd(localDir,true);
pendingChanges = workspace.GetPendingChanges();
workspace.CheckIn(pendingChanges, Comments);
}
The files, instead of being in the included changes in pending changes, are instead in the excluded changes like so:
and when the line that actually does the check-in runs, I'll get a "The array must contain at least one element" error, and the only way to fix it is to manually add those detected changes, and promote them to included changes, and I simply can't for the life of me figure out how to do that programatically though C#. If anyone has any guidance on what direction I should take for this, I would really appreciate it! Thank you!
Edit: I've also discovered another way to solve this by reconciling the folder, which also promotes the detected changes, but again the problem is I can't seem to figure out how to program that to do it automatically.
I know that running the visual studio developer command prompt, redirecting to the folder that this mapping is in, and the running "tf reconcile /promote" is one way, but I can only automate that as far as the /promote part, because that brings up a toolbox that a user would have to input into, which defeats the purpose of the automation. I'm at a loss.
Next Edit in response to TToni:
Next Edit in response to TToni:
I'm not entirely sure if I did this CreateWorkspaceParameters correctly (see picture 1), but this time it gave the same error, but the files were not even in the excluded portions. They just didn't show up anywhere in the pending changes (see picture 2).
Check this blog:
The workspace has a method GetPendingChangesWithCandidates, which actually gets all the “Excluded” changes. Code snippet is as below:
private void PendChangesAndCheckIn(string pathToWorkspace)
{
//Get Version Control Server object
VersionControlServer vs = collection.GetService(typeof
(VersionControlServer)) as VersionControlServer;
Workspace ws = vs.TryGetWorkspace(pathToWorkspace);
//Do Delete and Copy Actions to local path
//Create a item spec from the server Path
PendingChange[] candidateChanges = null;
string serverPath = ws.GetServerItemForLocalItem(pathToWorkspace);
List<ItemSpec> its = new List<ItemSpec>();
its.Add(new ItemSpec(serverPath, RecursionType.Full));
//get all candidate changes and promote them to included changes
ws.GetPendingChangesWithCandidates(its.ToArray(), true,
out candidateChanges);
foreach (var change in candidateChanges)
{
if (change.IsAdd)
{
ws.PendAdd(change.LocalItem);
}
else if (change.IsDelete)
{
ws.PendDelete(change.LocalItem);
}
}
//Check In all pending changes
ws.CheckIn(ws.GetPendingChanges(), "This is a comment");
}
I am trying to take ownership of a file and delete it via C#.
The file is iexplorer.exe, current owner by default - TrustedInstaller.
The method FileSecurity.SetOwner seems to set the specified ownership, but actually doesn't change the initial owner and throws no exception.
Obviously, the next attempt to delete the file throws an exception.
What should be changed in the code to take ownership of the file and delete it ?
var fileS = File.GetAccessControl(#"C:\Program Files (x86)\Internet Explorer\iexplore.exe");
fileS.SetOwner(new System.Security.Principal.NTAccount(Environment.UserDomainName, Environment.UserName));
File.Delete(#"C:\Program Files (x86)\Internet Explorer\iexplore.exe");
You must explicitly enable SeTakeOwnershipPrivilege:
Required to take ownership of an object without being granted
discretionary access. This privilege allows the owner value to be set
only to those values that the holder may legitimately assign as the
owner of an object. User Right: Take ownership of files or other
objects.

And/or take a look at his sample.

// privilege not held
// TODO: show an error message, write logs, etc.

You can probably shell/execute the same from your code.
