How do you get the latest version of source code using the Team Foundation Server SDK?

Question

I'm attempting to pull the latest version of source code out of TFS programmatically using the SDK, and what I've done somehow does not work:

string workspaceName = "MyWorkspace";
string projectPath = "/TestApp";
string workingDirectory = "C:\Projects\Test\TestApp";

VersionControlServer sourceControl; // actually instantiated before this method...

Workspace[] workspaces = sourceControl.QueryWorkspaces(workspaceName, sourceControl.AuthenticatedUser, Workstation.Current.Name);
if (workspaces.Length > 0)
{
    sourceControl.DeleteWorkspace(workspaceName, sourceControl.AuthenticatedUser);
}
Workspace workspace = sourceControl.CreateWorkspace(workspaceName, sourceControl.AuthenticatedUser, "Temporary Workspace");
try
{
    workspace.Map(projectPath, workingDirectory);
    GetRequest request = new GetRequest(new ItemSpec(projectPath, RecursionType.Full), VersionSpec.Latest);
    GetStatus status = workspace.Get(request, GetOptions.GetAll | GetOptions.Overwrite); // this line doesn't do anything - no failures or errors
}
finally
{
    if (workspace != null)
    {
        workspace.Delete();
    }
}

The approach is basically creating a temporary workspace, using the Get() method to grab all the items for this project, and then removing the workspace. Is this the correct way to do this? Any examples would be helpful.

Answer 1

Your approach is valid.

Your error is in your project path. Use something like this instead:

string projectPath = "$/PathToApp/TestApp";

Answer 2

I agree with Joerage that your server path is probably the culprit. To get more insight into what's happening, you need to wire up some events on the VersionControlServer object. At minimum you'll want Getting, NonFatalError, and Conflict.

Answer 3

I ended up using a different approach that seems to work, mainly taking advantage of the Item.DownloadFile() method:

VersionControlServer sourceControl; // actually instantiated...

ItemSet items = sourceControl.GetItems(sourcePath, VersionSpec.Latest, RecursionType.Full);

foreach (Item item in items.Items)
{
    // build relative path
    string relativePath = BuildRelativePath(sourcePath, item.ServerItem);

    switch (item.ItemType)
    {
    case ItemType.Any:
        throw new ArgumentOutOfRangeException("ItemType returned was Any; expected File or Folder.");
    case ItemType.File:
        item.DownloadFile(Path.Combine(targetPath, relativePath));
        break;
    case ItemType.Folder:
        Directory.CreateDirectory(Path.Combine(targetPath, relativePath));
        break;
    }
}
