如何在TFS中正确调用GetWorkspace?

问题描述

当前，当我调用 GetWorkspace 时，出现 ItemNotMappedException 异常，但是当我手动遍历工作区时，我可以使代码正常工作.这太奇怪了，我想知道在调用 GetWorkspace 之前是否应该进行刷新或其他操作?

Currently when I call GetWorkspace I get ItemNotMappedException exception, but when I iterate over workspaces manually I can get my code working. This is so bizarre that I am wondering if I should call some refresh or something before I call GetWorkspace?

这是我的代码:

Workspace active = null;
using (var tfs = new TfsTeamProjectCollection(uri))
{
    tfs.EnsureAuthenticated();
    VersionControlServer vcs = tfs.GetService<VersionControlServer>();

    // displaying info and manually finding desired workspace
    foreach (var ws in vcs.QueryWorkspaces(null, vcs.AuthorizedUser, Environment.MachineName))
    {
        Console.WriteLine(ws.Name);
        foreach (var f in ws.Folders)
        {
            Console.WriteLine($"  {f.LocalItem}");
            if (f.LocalItem == map_path)
                active = ws;
        }
    }

    // at this point workspace is found and I can work with it

    // but this will crash
    Workspace workspace = vcs.GetWorkspace(map_path);
}

我使用VS2015，TFS库是从NuGet存储库中获取的.它是"Microsoft.TeamFoundationServer.ExtendedClient"版本"15.112.1".

I use VS2015 and the library for TFS is fetched from NuGet repo. It is "Microsoft.TeamFoundationServer.ExtendedClient" version "15.112.1".

推荐答案

VersionControlServer.GetWorkspace 方法搜索当前计算机上的所有已知工作区，以标识具有明确或隐式映射的工作区提供的本地路径.如果找不到工作空间，则此方法将引发 ItemNotMappedException .

The VersionControlServer.GetWorkspace method searches all known workspaces on the current computer to identify a workspace that has explicitly or implicitly mapped the provided local path. If no workspace is found, this method throws an ItemNotMappedException.

尝试调用 Workstation.EnsureUpdateWorkspaceInfoCache 在您的代码中强制更新工作区信息缓存:

Try to call to Workstation.EnsureUpdateWorkspaceInfoCache in your code to force update the workspace information cache:

TfsTeamProjectCollection tpc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("<your-tfs-uri-here>"));
VersionControlServer tfServer = tpc.GetService<VersionControlServer>();
Workstation.Current.EnsureUpdateWorkspaceInfoCache(tfServer, tfServer.AuthorizedUser);

看看这个类似的问题: Microsoft.TeamFoundation.VersionControl.Client.ItemNotMappedException，即使工作空间存在并且具有映射

Have a look at this similar question: Microsoft.TeamFoundation.VersionControl.Client.ItemNotMappedException even when the workspace exists and has a mapping
