That is how UDP works. The port one side listens to is the same as the port the other side sends to. And then vice versa.

Yes, it is possible, and often happens. It really does not matter which port the server sends on since the client does not need that information.

thank you! how could i achieve it?

By studying socket communication and developing your code. Google will find many examples, tutorials etc.

Solution 1

As mentioned in the comments, this is how UDP communication works. The client will listen on port X and send on port Y. Therefore, the server will listen on port Y and send on port x. Very common scenario.

Sir, i am unable to find any sample code for it, Please provide me any link or code for it. This will be a great help to me. thank you!

There's nothing preventing you to write a request to a port and receiving the answer on another port.

I have worked only on the same ports. As i am new to the Socket Programming i am one bit afraid of the things. any code or example is expected...Please

ZurdoDev 13-Nov-15 8:26am

There are tons and tons of samples online as well as many on this site. Here is a link to search the articles for c# and udp. This has many examples to help you get going.

Solution 2

I have found a solution and believe me it is working fine...

All we have to do is to use Socket's "SendTo()" and "receiveFrom()" methods with the desired IPEndPoints
