Раздел «Технологии программирования».EndInvoke:

The EndInvoke method is used to retrieve the results of the asynchronous call. It can be called any time after BeginInvoke; if the asynchronous call has not completed, EndInvoke will block until it completes. The parameters of EndInvoke include the out and ref parameters of the method you want to execute asynchronously, plus the IAsyncResult returned by BeginInvoke.
