)
Parameters
- timeout
Type: System.TimeSpan
The Timespan that specifies how long the operation has to complete before timing out.

The AsyncCallback delegate that receives the notification of the asynchronous operation completion.
- state
Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous operation.
Return Value
