protected internal virtual void CancelLogin(
	IAsyncResult asyncResult


Type: System.IAsyncResult
A result returned from BeginLogin that represents the asynchronous call to cancel.


asyncResult was not returned from BeginLogin or the asynchronous call has already been concluded with a previous call to cancel or end.


SupportsCancellation is false.

When you override this method, you do not need to call the base method. This method is invoked when a Login operation is canceled. Either this method or EndLogin will be invoked to conclude the operation, but not both. After CancelLogin is called, the callback passed in to BeginLogin should not be invoked. Exceptions thrown from this method will be available in Error.
