分享TFS的二次开发中，调用VersionControlServer.ArtifactProvider.GetChangeset()方法异常
对TFS进行二次开发，想做一个通过输入WorkItem列表，然后得到这些WorkItem的ChangeSet列表。
UI如下：
但在调用TFS的函数的过程中，发现在调用VersionControlServer.ArtifactProvider.GetChangeset()时，
如果WorkItem数量比较多，特别是某个WorkItem的ChangeSet又很多的时候，经常都会出现异常，异常信息如下：
Team Foundation Server vstfs:///VersionControl/Changeset/135900 does not exist or is not accessible at this time.
Technical information (for administrator):
The operation has timed out
不知道哪位有没有遇到类似的问题，怎么解啊？
出现这种异常的原因有可能是哪种原因造成的？
期待有大婶帮忙，这个问题，困扰了我好几个月了。
环境：
TFS Server为TFS2008
现在程式引用的TFS DLL的版本为11.
关键代码如下：
