通过 API 创建 TFS 构建定义时，如果定义预先存在，我需要先删除：

if (BuildServer.QueryBuildDefinitions(teamProject).Any(d => d.Name == buildDefinitionName))
{
    buildDefinition = BuildServer.GetBuildDefinition(teamProject, buildDefinitionName);
    var builds = BuildServer.QueryBuilds(buildDefinition);
    if (builds != null && builds.Any())
    {
        Console.WriteLine("delete {0} builds for build definition: {1}", builds.Count(), buildDefinition.Name);
        BuildServer.DeleteBuilds(builds);
    }
    if (buildDefinition.Workspace.Mappings.Any())
    {
        var mappings = buildDefinition.Workspace.Mappings.Select(m => m.ServerItem).ToArray();
        foreach (var mapping in mappings)
        {
            Console.WriteLine("remove workspace mapping: {0}", mapping);
            buildDefinition.Workspace.RemoveMapping(mapping);
        }
    }
    Console.WriteLine("delete build definition: {0}", buildDefinition.Name);
    BuildServer.DeleteBuildDefinitions(new[] { buildDefinition });
}

这和后续的一样：

buildDefinition = BuildServer.CreateBuildDefinition(teamProject);
buildDefinition.Name = buildDefinitionName;

但是，当第一个构建运行时，它会引发有关冲突工作空间的错误：

Exception Message: Unable to create the workspace 'some-new-workspace' due to a mapping conflict. You may need to manually delete an old workspace. You can get a list of workspaces on a computer with the command 'tf workspaces /computer:%COMPUTERNAME%'.
Details: The path C:\some-path is already mapped in workspace some-old-workspace. (type MappingConflictException)

正如您在第一个 sn-p 中看到的，我尝试使用 .Workspace.RemoveMapping() 删除工作区没有任何效果。工作区仍然存在于构建控制器上。我可以手动删除它们，但是当我删除构建定义时它们确实应该被删除。 API中是否还有其他DeleteWorkspace()机制？

事实证明，它复杂的原因是构建创建的各种工作区的所有者可能是其他用户（构建代理在其下运行）。我找到了一种方法，它依赖于在工作区命名约定[build definition id]_[build agent id]_[workspace host] 中使用的先前构建定义 ID：

var workspaceNamePrefix = string.Concat(buildDefinition.Id, '_');
var workSpaces = VersionControlServer.QueryWorkspaces(null, null, null).Where(w => w.Name.StartsWith(workspaceNamePrefix)).ToArray();
for (var i = workSpaces.Count() - 1; i > -1; i--)
{
    try
    {
        workSpaces[i].Delete();
        Console.WriteLine("delete workspace: {0}", workSpaces[i].Name);
    }
    catch (ResourceAccessException rae)
    {
        Console.ForegroundColor = ConsoleColor.Yellow;
        Console.WriteLine(rae.Message);
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("workspace needs to be deleted by an administrator using the following command:");
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("tf workspace /delete {0};{1}", workSpaces[i].Name, workSpaces[i].OwnerName);
        Console.ResetColor();
    }
}
