C#代码检查TFS上是否存在工作空间

Question

我正在尝试创建一个自动化工具来从TFS获取最新代码.我需要检查系统上是否存在任何具有相同名称的工作区.如果存在则获取工作空间实例.否则创建工作区和映射.

我发现Microsoft.TeamFoundation.VersionControl.ClientVersionControlServer有Workspace GetWorkspace(string workspaceName, string workspaceOwner);获取现有工作空间的方法.但是如果系统上不存在工作空间,这将抛出异常.

所以请给我一个检查工作空间和映射是否存在的代码.

目前我有以下代码,我知道它的方法不正确

try
{
    //**Expected** an exception  as sometimes the workspace may not exist or Deleted    manually.
    workspace = versionControl.GetWorkspace(workspaceName, versionControl.AuthorizedUser);
    versionControl.DeleteWorkspace(workspaceName, versionControl.AuthorizedUser);
    workspace = null;
}
catch (Exception e)
{
    DialogResult res = MessageBox.Show("There are no workspace mapped. I am creating a new workspace mapped to your local folder named DevFolder.", "Error", MessageBoxButtons.YesNo);

    if (res == DialogResult.No)
    {
        return;
    }
}

if (workspace == null)
{
    var teamProjects = new List<TeamProject>(versionControl.GetAllTeamProjects(false));

    // if there are no team projects in this collection, skip it
    if (teamProjects.Count < 1)
    {
        MessageBox.Show("Please select a team project.");
        return;
    }

    // Create a temporary workspace2.
    workspace = versionControl.CreateWorkspace(workspaceName, versionControl.AuthorizedUser);

    // For this workspace, map a server folder to a local folder              
    ReCreateWorkSpaceMappings(workspace);

    createdWorkspace = true;

}

如果您不想依赖捕获异常,可以调用QueryWorkspaces

 workspace = versionControl.QueryWorkspaces(
                     workspaceName, 
                     versionControl.AuthorizedUser, 
                     Environment.MachineName).SingleOrDefault();

此代码将在此代码运行的计算机上查询用户的工作空间.如果集合为空,它将在工作空间中返回null,否则它将返回列表中的单个项目.在QueryWorkspaces返回更多项目(似乎不可能)的情况下,它仍会抛出,但这对我来说似乎没问题.

现在您可以检查映射

  if (workspace !=null)
  {
       foreach(var folder in workspace.Folders)
       {
             if (!folder.IsCloaked && folder.LocalItem != "some expected path")
             {
                  // mapping invalid, throw/log?
             }
       }
  }
