示例1: ConnectAsync
public bool ConnectAsync(EventHandler<SocketAsyncEventArgs> onCompletion)
{
if (socket.Connected)
{
// already connected, just invoke the 'on completion' event.
onCompletion.DynamicInvoke(null, null);
return false; // operation not pending - return synchronously
}
else
{
SocketAsyncEventArgs socketEventArgs = new SocketAsyncEventArgs()
{
RemoteEndPoint = new IPEndPoint(this.hostaddress, this.port)
};
socketEventArgs.Completed += onCompletion;
return socket.ConnectAsync(socketEventArgs);
}
}示例2: EventFire
private void EventFire(EventHandler evntHndlr, EventArgs ea)
{
if (evntHndlr == null)
return;
int i = 0;

catch (Exception ex)
{
//
// Eat the exception
//

}示例3: EventFire
private void EventFire(EventHandler evntHndlr, EventArgs ea)
{
// Make sure that the handler has methods bound to it.
if (evntHndlr == null)

// Iterate through the methods attached to the handler:
// 1 If an exception is thrown, swallow it
// 2 Make sure that Contorl-Invoke is used if appropriate.
int i = 0;

// any class that supports ISynchronizeInvoke interface
//

// If del.Target does not represent a control (or a class that

}

//

// is not required. This means that we are on the UI thread
// of that control.
