WorkflowApplication.BeginTerminate Method (String, AsyncCallback, Object)

Terminates a workflow instance asynchronously using the specified error message, callback method, and user-provided state.

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

Public Function BeginTerminate ( _
	reason As String, _
	callback As AsyncCallback, _
	state As Object _
) As IAsyncResult


Type: System.String
The reason for terminating the workflow instance.
Type: System.AsyncCallback
The method to be called when the BeginTerminate operation has completed.
Type: System.Object
An optional application-specific object that contains information about the asynchronous operation.

Return Value

Type: System.IAsyncResult
A reference to the current BeginTerminate operation.

This method schedules the termination of the workflow instance. To be notified when the termination has completed, use the OnCompleted handle.

To determine whether the BeginTerminate operation was successful, call EndTerminate(IAsyncResult). EndTerminate(IAsyncResult) can be called from inside or outside of the method reference in the callback parameter. If EndTerminate(IAsyncResult) is called before the BeginTerminate operation completes, it blocks until the BeginTerminate operation completes. By default, the BeginTerminate operation must complete in 30 seconds or a TimeoutException is thrown from EndTerminate(IAsyncResult).

This method terminates a workflow instance asynchronously using the IAsyncResult asynchronous design pattern. For more information, seeAsynchronous Programming Overview.
