HwndSource.IsDisposed Property


Gets a value that indicates whether Dispose() has been called on this HwndSource.

 virtual property bool IsDisposed { bool get(); };
public override bool IsDisposed { get; }
member this.IsDisposed : bool
Public Overrides ReadOnly Property IsDisposed As Boolean

Property Value

true if the object has had Dispose() called on it; otherwise, false.


Dispose initiates related cleanup work for the HWND. If Dispose is called through a thread that is different from the main UI thread, the cleanup work may be deferred until it can be posted to the main UI thread. The Disposed event is raised and the value of IsDisposed becomes false as soon as Dispose is called. During this time, if you call Dispose again, Dispose raises an exception.
