Description
Sends the specified data to the connected endpoint asynchronously.
When you call BeginSend it immediately returns an instance of a class that implements the IAsyncResult interface.
You may pass BeginSend the following parameters:
AsyncCallbackEvent, an event handler of type TAsyncCallbackEvent that is called once the specified data is sent.AsyncCallback, a method of type TAsyncCallback that is called once the specified data is sent.Offsetis a number of bytes to skip at the beginning of the data to send.Countis the maximum length of the data to send.Flagsis a set of flags that influence the behavior of Send. For more information, see the documentation of the send function in the MSDN.- A string (
S) or an array of bytes (B) to send.
Once your callback event handler or method is called, pass the returned instance of a class that implements the IAsyncResult interface to EndSend, in order to accept the incoming connection.
