Starts or resumes a workflow instance asynchronously using the specified time-out interval, callback method, and user-provided state.

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

public IAsyncResult BeginRun(
	TimeSpan timeout,
	AsyncCallback callback,
	object state
)

Parameters

timeout
Type: System.TimeSpan

The interval in which the resume operation must complete before the operation is canceled and a TimeoutException is thrown.

callback
Type: System.AsyncCallback

The method to be called when the resume operation has completed.

state
Type: System.Object

An optional application-specific object that contains information about the asynchronous operation.

Return Value

Type: System.IAsyncResult

A reference to the asynchronous run operation.

To determine whether the run operation was successful, call EndRun. EndRun can be called from inside or outside of the method reference in the callback parameter. If EndRun is called before the resume operation completes, it blocks until the resume operation completes. If the resume operation does not complete within the specified time-out interval a TimeoutException is thrown from EndRun.

This method starts or resumes a workflow asynchronously using the IAsyncResult asynchronous design pattern. For more information, seeAsynchronous Programming Overview.
