Assembly: System.ServiceModel (in system.servicemodel.dll)
public IAsyncResult BeginOpen ( TimeSpan timeout, AsyncCallback callback, Object state )
public final IAsyncResult BeginOpen ( TimeSpan timeout, AsyncCallback callback, Object state )
public final function BeginOpen ( timeout : TimeSpan, callback : AsyncCallback, state : Object ) : IAsyncResult
The Timespan that specifies how long the send operation has to complete before timing out.
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
An object, specified by the application, that contains state information associated with the asynchronous open operation.
Return ValueThe IAsyncResult that references the asynchronous open operation.
timeout is less than zero.
The communication object is in a Faulted state and cannot be modified.
