我遇到了这个异常“字典中不存在给定的键”，这表明字典中没有找到某些值，但奇怪的是我没有使用任何字典，我猜这是一些内部代码C# 的 TFS API。这是引发异常的代码部分：

if (wi.Validate().Count == 0)
{
     // Save the work item to submit changes
     wi.Save();
}
else
{
     Console.WriteLine("following errors was encountered when trying to save the work          item {0} : ", id);
     foreach (var e in wi.Validate())
                        {
           Console.WriteLine(" - '{0} '", e);
     }
}


                    // Close the work item
                    wi.Close(); 

                    // Submit the changes to the database
                    SubmitChangesToDatabase(id, author, statusChanged, previousChangeTime);  

                    // Open again the work item to go on with other updates
                    wi.Open();

这段代码是循环的一部分，我在其中获取工作项，使用 TFS API 执行一些更新，之后，我使用方法SubmitChangesToDatabase直接在数据库上更改只读字段。调用方法Open()时引发异常。堆栈跟踪如下：

当我的团队项目被配置为使用团队字段而不是 Aeea 路径时，我曾经有过这种情况。如果您更改了此设置并且某些工作项尚未指定团队，那么您将收到此错误。

如果您创建一个将“yourteamfield.team”设置为空的查询并批量更新所有工作项以具有一个值，则该错误应该会消失。
