如何使用Team Foundation Server SDK获取最新版本的源代码？

Question

我正在尝试使用SDK以编程方式从TFS中提取最新版本的源代码,而我所做的某些方法不起作用:

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();
    }
}

该方法基本上是创建临时工作空间,使用该Get()方法获取此项目的所有项目,然后删除工作空间.这是正确的方法吗？任何例子都会有所帮助.

我最终使用了一种似乎有用的不同方法,主要是利用了这种Item.DownloadFile()方法:

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;
    }
}

我完成并将代码实现为一个按钮作为web asp.net解决方案.

对于该项目的参考工作应补充Microsoft.TeamFoundation.Client和Microsoft.TeamFoundation.VersionControl.Client引用,并在代码中的语句using Microsoft.TeamFoundation.Client;和using Microsoft.TeamFoundation.VersionControl.Client;

    protected void Button1_Click(object sender, EventArgs e)
    {
        string workspaceName = "MyWorkspace";
        string projectPath = @"$/TeamProject"; // the container Project (like a tabel in sql/ or like a folder) containing the projects sources in a collection (like a database in sql/ or also like a folder) from TFS

        string workingDirectory = @"D:\New1";  // local folder where to save projects sources

        TeamFoundationServer tfs = new TeamFoundationServer("http://test-server:8080/tfs/CollectionName", System.Net.CredentialCache.DefaultCredentials);
                                                            // tfs server url including the  Collection Name --  CollectionName as the existing name of the collection from the tfs server 
        tfs.EnsureAuthenticated(); 

        VersionControlServer sourceControl = (VersionControlServer)tfs.GetService(typeof(VersionControlServer));

        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();
                Label1.Text = "The Projects have been brought into the Folder  " + workingDirectory;
            }
        }
    }

你的方法是有效的.

您的错误在您的项目路径中.使用这样的东西代替:

string projectPath = "$/PathToApp/TestApp";
