Unable to cast COM object of type 'System.__ComObject' to interface type ' \a. \a'.无法投COM对象
This operation failed because the QueryInterface call on the COM component for the > > interface with IID '{39C13A4D-011E-11D0-9675-0020AFD8ADB3}' failed due to the following error:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA).
任何人有这个例外的想法?
你在哪个平台上运行这个平台?这看起来像是一个DCOM错误 – 2011-05-03 12:25:20
