Message in Chinese (Simplified) (中文(简体))
IAsyncResult 实现“<var>X</var>”多次尝试完成同一个操作。这可能是由不正确的应用程序 IAsyncResult 实现或其他扩展性代码所致，比如，返回不正确 CompletedSynchronously 值或多次调用 AsyncCallback 的 IAsyncResult。
Unlocalized message
The IAsyncResult implementation '<var>X</var>' tried to complete a single operation multiple times. This could be caused by an incorrect application IAsyncResult implementation or other extensibility code, such as an IAsyncResult that returns incorrect CompletedSynchronously values or invokes the AsyncCallback multiple times.
