IAsyncResult.CompletedSynchronously Property

Gets an indication of whether the asynchronous operation completed synchronously.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

bool CompletedSynchronously { get; }
/** @property */
boolean 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.
