abstract OnBeginOpen : 
        timeout:TimeSpan * 
        callback:AsyncCallback * 
        state:Object -> IAsyncResult  
override OnBeginOpen : 
        timeout:TimeSpan * 
        callback:AsyncCallback * 
        state:Object -> IAsyncResult

Parameters

timeout
Type: System.TimeSpan

The Timespan that specifies how long the operation has to complete before timing out.

callback
Type: System.AsyncCallback

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

Type: System.IAsyncResult
The IAsyncResult that references the asynchronous operation.
