My outlook client has a shared folder "xxxx yyyy". However, the following code, which iterates all the folder and sub folder recursively, doesn't print out the folder. Why the code cannot get the folder?
private static void PrintAllPubFolder(ExchangeService service)
{
var folderView = new FolderView(int.MaxValue);
var findFolderResults = service.FindFolders(WellKnownFolderName.PublicFoldersRoot, folderView);
foreach (var folder in findFolderResults.Where(x => !ignore.Any(i => i == x.DisplayName)))
{
Console.WriteLine(folder.DisplayName);
PrintSubFolder(service, folder.Id, " ");
}
}
private static void PrintSubFolder(ExchangeService service, FolderId folderId, string p)
{
var folderView = new FolderView(int.MaxValue);
var findFolderResults = service.FindFolders(folderId, folderView);
foreach (var folder in findFolderResults.Where(x => !ignore.Any(i => i == x.DisplayName)))
{
Console.WriteLine("{0}{1}", p, folder.DisplayName);
PrintSubFolder(service, folder.Id, p + " ");
}
}
If your using Exchange 2010 or later don't use
var folderView = new FolderView(int.MaxValue);
Throttling will limit the results returned to 1000 so if you expect more the 1000 entries to be return then you'll need to page the results. However it doesn't make much sense to enumerate through every public folder to get the target look at the method in the following link
Searching Of Folders in Public Folders by giving its PATH Name
if the folder is in your mailbox then just do a search for that based on the name eg
FolderView ffView = new FolderView(1000);
ffView.Traversal = FolderTraversal.Deep;
SearchFilter fSearch = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, "xxxx yyyy");
FindFoldersResults ffResults = service.FindFolders(WellKnownFolderName.MsgFolderRoot, fSearch, ffView);

I want to create some folders in the document library in C#.
The folder structure should be as follows in the document library:
"98_Projekte" --> "Muster Mandant" --> "01 Test Subfolder"
In my C# code, I only create the sub folder "Muster Mandant" in "98_Projekte". That is correct, but I want afterwards to create new subfolders in "Muster Mandant" (see second foreach).
public static void AddFolder(ClientContext context, string[] folders)
{
Web web = context.Web;
var docLibrary = web.DefaultDocumentLibrary().RootFolder;
context.Load(docLibrary);
context.ExecuteQuery();
foreach (Microsoft.SharePoint.Client.Folder subFolder in docLibrary.Folders)
{
if (subFolder.Name == "98_Projekte")
{
subFolder.Folders.Add("Muster Mandant");
context.ExecuteQuery();
docLibrary = subFolder;
docLibrary.Update();
}
}
foreach (Microsoft.SharePoint.Client.Folder subSubFolder in docLibrary.Folders)
{
if (subSubFolder.Name == "Muster Mandant")
{
foreach (string folder in folders)
{
subSubFolder.Folders.Add(folder);
}
}
}
context.ExecuteQuery();
}
}
Do you have any solutions?
You may check below code.
public static Folder AddSubFolder(ClientContext context, Folder ParentFolder, string folderName)
{
Folder resultFolder=ParentFolder.Folders.Add(folderName);
context.ExecuteQuery();
return resultFolder;
}
static void Main(string[] args)
{
using (var context = new ClientContext("https://domain.sharepoint.com/sites/TST/"))
{
string password = "pw";
SecureString sec_pass = new SecureString();
Array.ForEach(password.ToArray(), sec_pass.AppendChar);
sec_pass.MakeReadOnly();
context.Credentials = new SharePointOnlineCredentials("lee#domain.onmicrosoft.com", sec_pass);
Web web = context.Web;
var folders = web.DefaultDocumentLibrary().RootFolder.Folders;
context.Load(folders);
context.ExecuteQuery();
foreach (Folder subFolder in folders)
{
if (subFolder.Name == "98_Projekte")
{
Folder parent1= AddSubFolder(context,subFolder,"Muster Mandant");
AddSubFolder(context, parent1, "01 Test Subfolder");
}
}
Console.WriteLine("Done");
Console.ReadKey();
}
}
I think the problem is that your code is expecting the .Folders property to contain all folders (recursive) and instead you are just getting the direct children of the root folder. In your 2nd loop check the context of the docLibrary.Folders property/collection and see what is returned.
I have the following code using CSOM to download a file from a sharepoint site:
public IEnumerable<FileUpload> DownloadFiles(string client, Guid userGuid, IEnumerable<Guid> fileUploadGuids)
{
using (var context = new ClientContext(documentStore))
{
client = client.ToLower();
var result = IntialSetUp(client, userGuid, fileUploadGuids, context);
context.Load(result, items => items.Include(
item => item.File.Name,
item => item[FileTitle],
item => item[FileRef]
));
context.ExecuteQuery();
List<FileUpload> fileUploads = new List<FileUpload>();
foreach (var item in result)
{
using (var fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, item[FileRef].ToString()))
{
using (var memory = new MemoryStream())
{
fileInfo.Stream.CopyTo(memory);
fileUploads.Add(new FileUpload()
{
Name = item[FileTitle].ToString(),
FileUploadGuid = new Guid(item.File.Name),
FileBytes = memory.ToArray()
});
}
}
}
return fileUploads;
}
}
public void AddNetworkCredentials(ClientContext context)
{
string login = ConfigurationManager.AppSettings["UserName"];
string password = ConfigurationManager.AppSettings["Password"];
context.Credentials = new NetworkCredential(login, password, ConfigurationManager.AppSettings["Domain"]);
context.ExecuteQuery();
}
public ListItemCollection IntialSetUp(string client, Guid userGuid, IEnumerable<Guid> fileUploadGuids, ClientContext context)
{
AddNetworkCredentials(context);
var list = context.Web.Lists.GetByTitle(client);
context.ExecuteQuery();
return GetItems(FileLeafRef, Array.ConvertAll(fileUploadGuids.ToArray(), x => x.ToString("N")), list, FieldType.File, documentStore + "/" + client + "/" + userGuid.ToString("N"));
}
This code will run fine the first time round, but every consecutive request will throw the following error:
The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.
This only happens for this service request and doesn't effect other requests that do not download the actual file, this leads me to believe it has something to do with the OpenBinaryDirect method but I haven't found anything describing this issue.
Any ideas as to what might be causing this and how it could be remedied?
notes:
Left in a bunch of ExecteQuerys for testing purposes.
The title of the file is actually a guid so we could have multiple
files with the same name (the file name is a separate column)
I'm trying to use the Live SDK (v5.6) to include backup/restore from OneDrive in my Windows Phone 8.1 Silverlight application. I can read/write to the standard "me/skydrive" directory, but I am having a horrible time in finding a way to upload/download to a specified directory. I can create the folder if it doesn't exist no problem.
I have been trying below with no luck.
var res = await _client.UploadAsync("me/skydrive/mydir", fileName, isoStoreFileStream, OverwriteOption.Overwrite);
I've also tried getting the directory ID and passing that in also.
var res = await _client.UploadAsync("me/skydrive/" + folderId, fileName, isoStoreFileStream, OverwriteOption.Overwrite);
Same error.. I receive 'mydir' or the id isn't supported...
"{request_url_invalid: Microsoft.Live.LiveConnectException: The URL contains the path 'mydir', which isn't supported."
Any suggestions? If you suggest an answer for the uploadasync, could you also include how I could download my file from the specified directory? Thanks!
Here's an extension method that checks if a folder is created and:
If created returns the folder id.
If not created, creates it and returns the folder id.
You can then use this id to upload to and download from that folder.
public async static Task<string> CreateDirectoryAsync(this LiveConnectClient client,
string folderName, string parentFolder)
{
string folderId = null;
// Retrieves all the directories.
var queryFolder = parentFolder + "/files?filter=folders,albums";
var opResult = await client.GetAsync(queryFolder);
dynamic result = opResult.Result;
foreach (dynamic folder in result.data)
{
// Checks if current folder has the passed name.
if (folder.name.ToLowerInvariant() == folderName.ToLowerInvariant())
{
folderId = folder.id;
break;
}
}
if (folderId == null)
{
// Directory hasn't been found, so creates it using the PostAsync method.
var folderData = new Dictionary<string, object>();
folderData.Add("name", folderName);
opResult = await client.PostAsync(parentFolder, folderData);
result = opResult.Result;
// Retrieves the id of the created folder.
folderId = result.id;
}
return folderId;
}
You then use this as:
string skyDriveFolder = await CreateDirectoryAsync(liveConnectClient, "<YourFolderNameHere>", "me/skydrive");
Now skyDriveFolder has the folder id that you can use when uploading and downloading. Here's a sample Upload:
LiveOperationResult result = await liveConnectClient.UploadAsync(skyDriveFolder, fileName,
fileStream, OverwriteOption.Overwrite);
ADDITION TO COMPLETE THE ANSWER BY YnotDraw
Using what you provided, here's how to download a text file by specifying the file name. Below does not include if the file is not found and other potential exceptions, but here is what works when the stars align properly:
public async static Task<string> DownloadFileAsync(this LiveConnectClient client, string directory, string fileName)
{
string skyDriveFolder = await OneDriveHelper.CreateOrGetDirectoryAsync(client, directory, "me/skydrive");
var result = await client.DownloadAsync(skyDriveFolder);
var operation = await client.GetAsync(skyDriveFolder + "/files");
var items = operation.Result["data"] as List<object>;
string id = string.Empty;
// Search for the file - add handling here if File Not Found
foreach (object item in items)
{
IDictionary<string, object> file = item as IDictionary<string, object>;
if (file["name"].ToString() == fileName)
{
id = file["id"].ToString();
break;
}
}
var downloadResult= await client.DownloadAsync(string.Format("{0}/content", id));
var reader = new StreamReader(downloadResult.Stream);
string text = await reader.ReadToEndAsync();
return text;
}
And in usage:
var result = await DownloadFile(_client, "MyDir", "backup.txt");
I need to retrieve items from the 'Inbox\test\final' Exchange folder using EWS. The folder is provided by a literal path as written above. I know I can split this string into folder names and recursively search for the necessary folder, but is there a more optimal way that can translate a string path into a folder instance or folder ID?
I'm using the latest EWS 2.0 assemblies. Do these assemblies provide any help, or am I stuck with manual recursion?
You could use an extended property as in this example
private string GetFolderPath(ExchangeService service, FolderId folderId)
{
var folderPathExtendedProp = new ExtendedPropertyDefinition(26293, MapiPropertyType.String);
var folderPropSet = new PropertySet(BasePropertySet.FirstClassProperties) { folderPathExtendedProp };
var folder = Folder.Bind(service, folderId, folderPropSet);
string path = null;
folder.TryGetProperty(folderPathExtendedProp, out path);
return path?.Replace("\ufffe", "\\");
}
Source: https://social.msdn.microsoft.com/Forums/en-US/e5d07492-f8a3-4db5-b137-46e920ab3dde/exchange-ews-managed-getting-full-path-for-a-folder?forum=exchangesvrdevelopment
Since Exchange Server likes to map everything together with Folder.Id, the only way to find the path you're looking for is by looking at folder names.
You'll need to create a recursive function to go through all folders in a folder collection, and track the path as it moves through the tree of email folders.
Another parameter is needed to track the path that you're looking for.
public static Folder GetPathFolder(ExchangeService service, FindFoldersResults results,
string lookupPath, string currentPath)
{
foreach (Folder folder in results)
{
string path = currentPath + #"\" + folder.DisplayName;
if (folder.DisplayName == "Calendar")
{
continue;
}
Console.WriteLine(path);
FolderView view = new FolderView(50);
SearchFilter filter = new SearchFilter.IsEqualTo(FolderSchema.Id, folder.Id);
FindFoldersResults folderResults = service.FindFolders(folder.Id, view);
Folder result = GetPathFolder(service, folderResults, lookupPath, path);
if (result != null)
{
return result;
}
string[] pathSplitForward = path.Split(new[] { "/" }, StringSplitOptions.RemoveEmptyEntries);
string[] pathSplitBack = path.Split(new[] { #"\" }, StringSplitOptions.RemoveEmptyEntries);
string[] lookupPathSplitForward = lookupPath.Split(new[] { "/" }, StringSplitOptions.RemoveEmptyEntries);
string[] lookupPathSplitBack = lookupPath.Split(new[] { #"\" }, StringSplitOptions.RemoveEmptyEntries);
if (ArraysEqual(pathSplitForward, lookupPathSplitForward) ||
ArraysEqual(pathSplitBack, lookupPathSplitBack) ||
ArraysEqual(pathSplitForward, lookupPathSplitBack) ||
ArraysEqual(pathSplitBack, lookupPathSplitForward))
{
return folder;
}
}
return null;
}
"ArraysEqual":
public static bool ArraysEqual<T>(T[] a1, T[] a2)
{
if (ReferenceEquals(a1, a2))
return true;
if (a1 == null || a2 == null)
return false;
if (a1.Length != a2.Length)
return false;
EqualityComparer<T> comparer = EqualityComparer<T>.Default;
for (int i = 0; i < a1.Length; i++)
{
if (!comparer.Equals(a1[i], a2[i])) return false;
}
return true;
}
I do all the extra array checking since sometimes my clients enter paths with forward slashes, back slashes, starting with a slash, etc. They're not tech savvy so let's make sure the program works every time!
As you go through each directory, compare the desired path to the iterated path. Once it's found, bubble up the Folder object that it's currently on. You'll need to create a search filter for that folder's id:
FindItemsResults<item> results = service.FindItems(foundFolder.Id, searchFilter, view);
Loop through the emails in results!
foreach (Item item in results)
{
// do something with item (email)
}
Here's my recursive descent implementation, which attempts to fetch as little information as possible on the way to the target folder:
private readonly FolderView _folderTraversalView = new FolderView(1) { PropertySet = PropertySet.IdOnly };
private Folder TraceFolderPathRec(string[] pathTokens, FolderId rootId)
{
var token = pathTokens.FirstOrDefault();
var matchingSubFolder = _exchangeService.FindFolders(
rootId,
new SearchFilter.IsEqualTo(FolderSchema.DisplayName, token),
_folderTraversalView)
.FirstOrDefault();
if (matchingSubFolder != null && pathTokens.Length == 1) return matchingSubFolder;
return matchingSubFolder == null ? null : TraceFolderPathRec(pathTokens.Skip(1).ToArray(), matchingSubFolder.Id);
}
For a '/'-delimited path, it can be called as follows:
public Folder TraceFolderPath(string folderPath)
{ // Handle folder names with '/' in them
var tokens = folderPath
.Replace("\\/", "<slash>")
.Split('/')
.Select(t => t.Replace("<slash>", "/"))
.ToArray();
return TraceFolderPathRec(tokens, WellKnownFolderName.MsgFolderRoot);
}
No, you don't need recursion and you efficiently go straight to the folder. This uses the same extended property as Tom, and uses it to apply a search filter:
using Microsoft.Exchange.WebServices.Data; // from nuget package "Microsoft.Exchange.WebServices"
...
private static Folder GetOneFolder(ExchangeService service, string folderPath)
{
var propertySet = new PropertySet(BasePropertySet.IdOnly);
propertySet.AddRange(new List<PropertyDefinitionBase> {
FolderSchema.DisplayName,
FolderSchema.TotalCount
});
var pageSize = 100;
var folderView = new FolderView(pageSize)
{
Offset = 0,
OffsetBasePoint = OffsetBasePoint.Beginning,
PropertySet = propertySet
};
folderView.Traversal = FolderTraversal.Deep;
var searchFilter = new SearchFilter.IsEqualTo(ExchangeExtendedProperty.FolderPathname, folderPath);
FindFoldersResults findFoldersResults;
var baseFolder = new FolderId(WellKnownFolderName.MsgFolderRoot);
var localFolderList = new List<Folder>();
do
{
findFoldersResults = service.FindFolders(baseFolder, searchFilter, folderView);
localFolderList.AddRange(findFoldersResults.Folders);
folderView.Offset += pageSize;
} while (findFoldersResults.MoreAvailable);
return localFolderList.SingleOrDefault();
}
...
public static class ExchangeExtendedProperty
{
/// <summary>PR_FOLDER_PATHNAME String</summary>
public static ExtendedPropertyDefinition FolderPathname { get => new ExtendedPropertyDefinition(0x66B5, MapiPropertyType.String); }
}
The path will need to be prefixed with a backslash, ie. \Inbox\test\final.
How to get all folders name of gmail using ImapX lib?
I read in http://hellowebapps.com/2010-02-09/imapx-net-library-to-manage-imap-folders/ but not found get all folder part.
here is how you get the list of all folders...
FolderCollection folders = client.GetFolders();
foreach (Folder myfolder in folders)
{
MessageBox.Show(myfolder.Name);
}
then use the name with:
ImapX.MessageCollection messages = client.Folders["Spam"].Search("ALL", true);
note that folder name is a case sensitive...
You can iterate the SubFolder collection and can get all of those gamail folders and thier path. An example:
var client = new ImapClient(...);
client.Connection();
client.LogIn(...);
foreach (var item in WalkFolderTree(client.Folders))
{
Console.WriteLine(item.FolderPath);
}
client.LogOut();
You have to custom implement the traversal code like:
public IEnumerable<Folder> WalkFolderTree(FolderCollection folders)
{
foreach (var item in folders)
{
if (item.HasChildren)
{
WalkFolderTree(item.SubFolder);
}
yield return item;
}
}
Then it will list all of the folders like:
INBOX
...
[Gmail]
[Gmail]/All Mail
[Gmail]/Drafts
[Gmail]/Sent Mail
[Gmail]/Spam
[Gmail]/Starred
[Gmail]/Trash
Here's how:
public List<string> getMailboxes(string emailAddress, string emailPassword)
{
var client = new ImapClient("imap.gmail.com", 993, true, true);
if (client.Connect())
{
if (client.Login(emailAddress, emailPassword))
{
//get all parent folers
var folders = client.Folders;
foreach (var parentFolder in folders)
{
//get parent folder path
var parentPath = parentFolder.Path;
//check if every parent folder has subfolder
if (parentFolder.HasChildren)
{
var subfolders = parentFolder.SubFolders;
foreach(var subfolder in subfolders)
{
var subPath = subfolder.Path;
}
}
}
}
}
}
