IAsyncResult.CompletedSynchronously Property

Gets an indication of whether the asynchronous operation completed synchronously.

[Visual Basic]
ReadOnly Property CompletedSynchronously As Boolean
bool CompletedSynchronously {get;}
__property bool get_CompletedSynchronously();
function get CompletedSynchronously() : Boolean;

Property Value

true if the asynchronous operation completed synchronously; otherwise, false.


If the synchronous completion of the call is detected in the AsyncCallback delegate, it is probable that the thread that initiated the asynchronous operation is the current thread.

Notes to Implementers:  Most implementers of the IAsyncResult interface will not use this property and should return false.

Notes to Callers:  Use this property to determine if the asynchronous operation completed synchronously. For example, this property can return true for an asynchronous I/O operation if the I/O request was small.
