We Keep Coding

Programmatically retrieve list of source folders and create one if not present - C# + VSTS 2017

I am trying to automate some processes to make life a bit easier. We have multiple requests from the team to create a folder in TFS 2017 (they do not have permissions) and then set up the associated builds for that source control folder.
The build creation part I think I have a way to do, but querying our on premise TFS 2017 server to get a list of folders under a certain path is proving tricky. So far I am having trouble even connecting to the server in the first place with this :
var collectionUri = "http://tfs-server:8080/tfs/DefaultCollection/";
var teamProjectName = "MYPROJECT";
Uri uri = new Uri(collectionUri);
var clientCredentials = new VssCredentials(new WindowsCredential(new NetworkCredential("USERNAME", "PASSWORD", "COLLECTIONNAME")));
var connection = new VssConnection(uri, clientCredentials);
var sourceControlServer = connection.GetClient<TfvcHttpClient>();
That throws an exception : Error converting value "System.Security.Principal.WindowsIdentity;" to type 'Microsoft.VisualStudio.Services.Identity.IdentityDescriptor'
Can someone help me to get connected to the server first please! Documentation on this is very hard to find, and I dont see any examples that actually work.
What I was going to look at next was creating the folder if it doesn't exist. No idea how to do that yet, maybe using
sourceControlServer.GetBranchAsync(teamProjectName + FolderName);
Thanks!
EDIT:
Ok I got it to not error creating the connection by doing this instead :
Uri uri = new Uri("http://tfs-server:8080/tfs/DefaultCollection/");
var clientCredentials = new VssCredentials(new WindowsCredential(new NetworkCredential("USERNAME", "PASSWORD", "DOMAIN")));
var buildServer = new BuildHttpClient(uri, clientCredentials);
var sourceControlServer = new TfvcHttpClient(uri, clientCredentials);
So now to just figure out how to list and create folders from TFS and to create builds!
EDIT:
So I have got the querying working, so I can check if a folder exists under a path like this :
var teamProjectName = "USA";
Uri uri = new Uri("http://tfs-server:8080/tfs/DefaultCollection/");
var clientCredentials = new VssCredentials(new WindowsCredential(new NetworkCredential("USERNAME", "PASSWORD", "DOMAIN")));
TfvcHttpClient sourceControlServer = new TfvcHttpClient(uri, clientCredentials);
List<TfvcItem> branchItems;
using (sourceControlServer) {
branchItems = sourceControlServer.GetItemsAsync("$/USA/Development/NewFolder", VersionControlRecursionType.OneLevel).Result;
}
return branchItems.Count > 0;
That will find all the items under that folder. So if there isnt a folder, it will return 0, so I can go ahead and create that folder.
So next problem, is how to create the folder. Using CreateChangesetAsync.

Update:
To use Client API and CreateChangesetAsync method to create files in TFVC, you could refer below sample console app:
using Microsoft.TeamFoundation.SourceControl.WebApi;
using Microsoft.VisualStudio.Services.Common;
using Microsoft.VisualStudio.Services.WebApi;
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp1
{
internal class Program
{
internal static async Task Main(string[] args)
{
var orgUrl = new Uri(args[0]);
string serverPath = args[1];
string localPath = args[2];
string contentType = args[3];
string pat = args[4];
var changes = new List<TfvcChange>()
{
new TfvcChange()
{
ChangeType = VersionControlChangeType.Add,
Item = new TfvcItem()
{
Path = serverPath,
ContentMetadata = new FileContentMetadata()
{
Encoding = Encoding.UTF8.WindowsCodePage,
ContentType = contentType,
}
},
NewContent = new ItemContent()
{
Content = Convert.ToBase64String(File.ReadAllBytes(localPath)),
ContentType = ItemContentType.Base64Encoded
}
}
};
var changeset = new TfvcChangeset()
{
Changes = changes,
Comment = $"Added {serverPath} from {localPath}"
};
var connection = new VssConnection(orgUrl, new VssBasicCredential(string.Empty, pat));
var tfvcClient = connection.GetClient<TfvcHttpClient>();
await tfvcClient.CreateChangesetAsync(changeset);
}
}
}
Besides, instead of using tf command line, please kindly check solution here:
C# TFS API: show project structure with folders and files, including their ChangeType (checked out, deleted,renamed) like in visual studio

Getting files/folders from sharepoint via the api in c#

I'm trying to link a c# application to a sharepoint directory, so I can create folders, download and upload files. However I am strugling with connecting to the correct folder.
I can retrieve the content from allitems.aspx, but I am not sure how to actually get the content from folder.
I have tried using the ClientContext - something like this:
ClientContext cxt = new ClientContext("https://xx.sharepoint.com/sites/");
cxt.Credentials = GetCredentials();
List list = cxt.Web.Lists.GetByTitle("Kontrakter");
var test = list.Views;
var test1 = cxt.Web.Lists;
cxt.Load(test1);
cxt.Load(list);
cxt.Load(test);
var a = 4;
var fullUri = new Uri("https://xx.sharepoint.com/sites/yy/Kontrakter/AllItems.aspx");
//var folder = cxt.Web.GetFolderByServerRelativeUrl(fullUri.AbsolutePath);
using (var rootCtx = new ClientContext(fullUri.GetLeftPart(UriPartial.Authority)))
{
rootCtx.Credentials = GetCredentials();
Uri webUri = Web.WebUrlFromPageUrlDirect(rootCtx, fullUri);
using (var ctx1 = new ClientContext(webUri))
{
ctx1.Credentials = GetCredentials();
var list1 = ctx1.Web.GetList(fullUri.AbsolutePath);
ctx1.Load(list1.RootFolder.Files);
ctx1.ExecuteQuery();
Console.WriteLine(list.RootFolder.Files.Count);
}
}
or via normal api calls like this:
https://xx.sharepoint.com/_api/Web/GetFolderByServerRelativeUrl('Kontrakter/Forms')/Files
The only way I can find some data is if I look into 'Shared documents/Forms'
I'm having problems understanding the directory structure and how I can actually find the content of files/folders.
Thanks in advance :)

Turned out I was missing a /sites in one of my uris.

Dropbox C# API v2 List Team folder contents

Good afternoon,
I am trying to get the list of directories from the dropbox API for the team members in business dropbox.
The documentation seems to be somewhat unclear and frustratingly difficult to get contents. Therefore my code could off somewhat and hence why i am having issues. I have a development token for both Team and my admin user.
using (var client = new DropboxTeamClient("my token"))
{
var teamInfo = await client.Team.GetInfoAsync();
var teamName = teamInfo.Name;
var numberOfUsers = teamInfo.NumProvisionedUsers;
var memListResult = await client.Team.MembersListAsync();
foreach (var m in memListResult.Members)
{
var accountId = m.Profile.AccountId;
var email = m.Profile.Email;
Console.WriteLine($"Id {accountId} - email is {email}");
}
var accId = memListResult.Members.First(x => x.Profile.Email.Equals("myEmail"))
?.Profile.AccountId;
var memId = memListResult.Members.First(x => x.Profile.Email.Equals("myEmail"))
?.Profile.TeamMemberId;
var dbx = client.AsAdmin(memId);
try
{
var full = await dbx.Users.GetCurrentAccountAsync();
Console.WriteLine("{0} - {1}", full.Name.DisplayName, full.Email);
await ListRootFolder(dbx, true);
}
catch (Exception e)
{
Console.WriteLine(e);
}
}
private async Task ListRootFolder(DropboxClient dbx)
{
var list = await dbx.Files.ListFolderAsync(string.Empty);
//var tlist = await dbx.
// show folders then files
foreach (var item in list.Entries.Where(i => i.IsFolder))
{
Console.WriteLine("D {0}/", item.Name);
}
foreach (var item in list.Entries.Where(i => i.IsFile))
{
Console.WriteLine("F{0,8} {1}", item.AsFile.Size, item.Name);
}
}
No my issue is that i can only ever get what shows in my directory. So for example i have logged into the web browser into dropbox i have three directories.
|
|- User Dir 'This is my home directory'
|- Team Dir 'This is a directory for the team'
|- Sample folder
The team has access to the Team dir and sample folder. All i would like to do is simply get the list of directories.
I must be doing something completely wrong, i have also tried the overrides for dbx.Files.ListFolderAsync i have set includeMountedFolders parameter to true and still only lists two files in my profile.
I have also tried using the user token instead of the Team token and setting asAdmin.
Apologies on the code is somewhat untidy i just want to get it working before i refactor.
Any help would be appreciated.
Thanks

It sounds like you want to access your "team space". You need to explicitly specify this when calling the API. I recommend reading the Namespace Guide, which covers this in detail.
The .NET SDK supports setting the Dropbox-Api-Path-Root header, via DropboxClient.WithPathRoot.
First, you can get the root info from GetCurrentAccountAsync:
var accountInfo = await dbx.Users.GetCurrentAccountAsync();
Console.WriteLine(accountInfo.RootInfo.RootNamespaceId);
Then, you can access the team shared space by using DropboxClient.WithPathRoot to set the Dropbox-Api-Path-Root header as desired, like:
dbx = dbx.WithPathRoot(new PathRoot.NamespaceId(accountInfo.RootInfo.RootNamespaceId));
var res = await this.client.Files.ListFolderAsync(path: "");
foreach (var entry in res.Entries)
{
Console.WriteLine(entry.Name);
}

Unable to retrieve docs in a specific folder in google docs using c#

I'm trying to retrieve all documents in a folder in google docs using the below function as give in API documentation.. but still the function is returning the titles of all the documents and not only of that particular folder..
public DocumentsFeed RetrieveDocsInFolder(DocumentsService service, string folder, string email)
{
AtomCategory folderCategory = new AtomCategory(folder,
new AtomUri("http://schemas.google.com/docs/2007/folders/" + email));
QueryCategory folderQueryCategory = new QueryCategory(folderCategory);
DocumentsListQuery query = new DocumentsListQuery();
query.Categories.Add(folderQueryCategory);
query.CategoryQueriesAsParameter = true;
return service.Query(query);
}

Try the following code:
public DocumentsFeed RetrieveDocsInFolder(DocumentsService service, string folder)
{
string uri = String.Format(DocumentsListQuery.foldersUriTemplate, folder);
DocumentsListQuery query = new DocumentsListQuery(uri);
return service.Query(query);
}
I'm assuming folder is the resource ID of the folder you want to retrieve the content for.

SharePoint 2010 - Client Object Model - Add attachment to ListItem

I have a SharePoint List to which I'm adding new ListItems using the Client Object Model.
Adding ListItems is not a problem and works great.
Now I want to add attachments.
I'm using the SaveBinaryDirect in the following manner:
File.SaveBinaryDirect(clientCtx, url.AbsolutePath + "/Attachments/31/" + fileName, inputStream, true);
It works without any problem as long as the item that I'm trying to add the attachment to, already has an attachment that was added through the SharePoint site and not using the Client Object Model.
When I try to add an attachment to a item that doesnt have any attachments yet, I get the following errors (both happen but not with the same files - but those two messages appear consistently):
The remote server returned an error: (409) Conflict
The remote server returned an error: (404) Not Found
I figured that maybe I need to create the attachment folder first for this item.
When I try the following code:
clientCtx.Load(ticketList.RootFolder.Folders);
clientCtx.ExecuteQuery();
clientCtx.Load(ticketList.RootFolder.Folders[1]); // 1 -> Attachment folder
clientCtx.Load(ticketList.RootFolder.Folders[1].Folders);
clientCtx.ExecuteQuery();
Folder folder = ticketList.RootFolder.Folders[1].Folders.Add("33");
clientCtx.ExecuteQuery();
I receive an error message saying:
Cannot create folder "Lists/Ticket System/Attachment/33"
I have full administrator rights for the SharePoint site/list.
Any ideas what I could be doing wrong?
Thanks, Thorben

I struggled for a long time with this problem too, so I thought I'd post a complete code sample showing how to successfully create a list item and add an attachment.
I am using the Client Object API to create the list item, and the SOAP web service to add the attachment. This is because, as noted in other places on the web, the Client Object API can only be used to add attachments to an item where the item's upload directory already exists (eg. if the item already has an attachment). Else it fails with a 409 error or something. The SOAP web service copes with this OK though.
Note that another thing I had to overcome was that even though I added the SOAP reference using the following URL:
https://my.sharepoint.installation/personal/test/_vti_bin/lists.asmx
The URL that VS actually added to the app.config was:
https://my.sharepoint.installation/_vti_bin/lists.asmx
I had to manually change the app.config back to the correct URL, else I would get the error:
List does not exist.
The page you selected contains a list that does not exist. It may have been deleted by another user.
0x82000006
Here is the code:
void CreateWithAttachment()
{
const string listName = "MyListName";
// set up our credentials
var credentials = new NetworkCredential("username", "password", "domain");
// create a soap client
var soapClient = new ListsService.Lists();
soapClient.Credentials = credentials;
// create a client context
var clientContext = new Microsoft.SharePoint.Client.ClientContext("https://my.sharepoint.installation/personal/test");
clientContext.Credentials = credentials;
// create a list item
var list = clientContext.Web.Lists.GetByTitle(listName);
var itemCreateInfo = new ListItemCreationInformation();
var newItem = list.AddItem(itemCreateInfo);
// set its properties
newItem["Title"] = "Created from Client API";
newItem["Status"] = "New";
newItem["_Comments"] = "here are some comments!!";
// commit it
newItem.Update();
clientContext.ExecuteQuery();
// load back the created item so its ID field is available for use below
clientContext.Load(newItem);
clientContext.ExecuteQuery();
// use the soap client to add the attachment
const string path = #"c:\temp\test.txt";
soapClient.AddAttachment(listName, newItem["ID"].ToString(), Path.GetFileName(path),
System.IO.File.ReadAllBytes(path));
}
Hope this helps someone.

I have discussed this question with Microsoft. Looks like that only one way to create attachments remotely is List.asmx web service. I have tried to create this subfolder also and with no success.

With Sharepoint 2010 there was no way to upload a first attachment to a list item using the COM. The recommendation was to use the Lists web service inmstead.
With Sharepoint 2013 it works.
AttachmentCreationInformation newAtt = new AttachmentCreationInformation();
newAtt.FileName = "myAttachment.txt";
// create a file stream
string fileContent = "This file is was ubloaded by client object meodel ";
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
byte[] buffer = enc.GetBytes(fileContent);
newAtt.ContentStream = new MemoryStream(buffer);
// att new item or get existing one
ListItem itm = list.GetItemById(itemId);
ctx.Load(itm);
// do not execute query, otherwise a "version conflict" exception is rised, but the file is uploaded
// add file to attachment collection
newAtt.ContentStream = new MemoryStream(buffer);
itm.AttachmentFiles.Add(newAtt);
AttachmentCollection attachments = itm.AttachmentFiles;
ctx.Load(attachments);
ctx.ExecuteQuery();
// see all attachments for list item
// this snippet works if the list item has no attachments
This method is used in http://www.mailtosharepoint.net/

It reflects rather poorly on the Microsoft SharePoint team for not coming forward with an acknowledgement of the issue and a usable suggestion on how to resolve it. Here is how I dealt with it:
I am using the new SharePoint 2010 managed client that ships with the product. Hence, I already have a SharePoint ClientContext with credentials. The following function adds an attachment to a list item:
private void SharePoint2010AddAttachment(ClientContext ctx,
string listName, string itemId,
string fileName, byte[] fileContent)
{
var listsSvc = new sp2010.Lists();
listsSvc.Credentials = _sharePointCtx.Credentials;
listsSvc.Url = _sharePointCtx.Web.Context.Url + "_vti_bin/Lists.asmx";
listsSvc.AddAttachment(listName, itemId, fileName, fileContent);
}
The only prerequisite for the code above is to add to the project (I used Visual Studio 2008) a _web_reference_ I called sp2010 which is created from the URL of: http:///_vti_bin/Lists.asmx

I've used and tried this one on my CSOM (SharePoint Client Object Model) application and it works for me
using (ClientContext context = new ClientContext("http://spsite2010"))
{
context.Credentials = new NetworkCredential("admin", "password");
Web oWeb = context.Web;
List list = context.Web.Lists.GetByTitle("Tasks");
CamlQuery query = new CamlQuery();
query.ViewXml = "<View><Where><Eq><FieldRef Name = \"Title\"/><Value Type=\"String\">New Task Created</Value></Eq></Where></View>";
ListItemCollection listItems = list.GetItems(query);
context.Load(listItems);
context.ExecuteQuery();
FileStream oFileStream = new FileStream(#"C:\\sample.txt", FileMode.Open);
string attachmentpath = "/Lists/Tasks/Attachments/" + listItems[listItems.Count - 1].Id + "/sample.txt";
Microsoft.SharePoint.Client.File.SaveBinaryDirect(context, attachmentpath, oFileStream, true);
}
Note: Only works if item folder has been created already
