 ## Remarks
  <xref:System.Net.Sockets.Socket.EndSendTo%2A> completes the asynchronous send operation started in <xref:System.Net.Sockets.Socket.BeginSendTo%2A>.
 
- Before calling <xref:System.Net.Sockets.Socket.BeginSendTo%2A>, you need to create a callback method that implements the <xref:System.AsyncCallback> delegate. This callback method executes in a separate thread and is called by the system after <xref:System.Net.Sockets.Socket.BeginReceive%2A> returns. The callback method must accept the <xref:System.IAsyncResult> returned by the <xref:System.Net.Sockets.Socket.BeginSendTo%2A> method as a parameter.

  Within the callback method, call the <xref:System.IAsyncResult.AsyncState%2A> method of the <xref:System.IAsyncResult> parameter to obtain the sending <xref:System.Net.Sockets.Socket>. After obtaining the <xref:System.Net.Sockets.Socket>, you can call the <xref:System.Net.Sockets.Socket.EndSendTo%2A> method to successfully complete the send operation and return the number of bytes sent.
