Asynchronous Socket Connection

Question

Are there any fast way to learn Asynchronous socket tcp programming or are there any libraries available to utilize system.socket in a short amount of time?

My synchronous tcp client couldn't hold the program I'm working on because it needs to listen for a long period of time (10 to 60 seconds), which of course doesn't work in synchronous connection.

Thanks.

I suppose you could quickly whip up some code copycatting from msdn's async [server](http://msdn.microsoft.com/en-us/library/5w7b7x5f.aspx) and [client](http://msdn.microsoft.com/en-us/library/bbx2eya8.aspx) samples. then again, by the time it took you and me to post you could probably have mastered the basics already... — mtijn, Aug 09 '11 at 11:39

@mtijn: Actually I checked msdn and googled for hours for possible solutions, but I couldn't get them to work. How about libraries are there any? I'm using c# — user741630, Aug 09 '11 at 11:57
well what's wrong with just the .NET Sockets? They support async sockets too, as demonstrated in the 2 articles of my first comment. if you have a demo of your attempts post it so we can better help you overcome any difficulties. — mtijn, Aug 09 '11 at 12:12
This is a perfect use case for the Async CTP - there are multiple samples on using the async/await keywords to use the waiting time to do other useful work. — Stephen Chung, Aug 10 '11 at 02:35

I finally got it to work. I stand corrected. It appears that an synchronous socket does work for listening for long period of time. The reason why my earlier attempt wasn't working is because I'm using a NetworkStream, but I found out that it's possible to use a socket without a NetworkStream.

Socket server = new Socket(AddressFamily.InterNetwork,
                 SocketType.Stream, ProtocolType.Tcp);

Then use

socket.Send and socket.Receive
