Sends data asynchronously to a connected ProxySocket.
An IAsyncResult that references the asynchronous send.
Prior to sending data, the socket must be connected using either a call to Connect method or a call to Listen and Accept methods.
The BeginSend method starts asynchronously sending data through a ProxySocket. You should create a callback method that implements the AsyncCallback delegate. This callback method should use the EndSend method to complete the asynchronous operation. See the .NET Framework SDK Reference for more information on asynchronous methods.
