IAsyncResult.CompletedSynchronously Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets a value that indicates whether the asynchronous operation completed synchronously.

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

Syntax

'Declaration
ReadOnly Property CompletedSynchronously As Boolean
bool CompletedSynchronously { get; }

Property Value

Type: System.Boolean
true if the asynchronous operation completed synchronously; otherwise, false.

Remarks

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.
