Closing socket object not releasing port no in C#.

Question

Hi Friends,

I need your help. 

I am iterating over all local network interfaces(network adapter) to bind socket object. I am following below process:

 

(01.)  Creating socket object.

(02.)  Iterating over network interfaces & binding socket object.

(03.)  Using socket to send data on network.

(04.)  Closing socket object.

 

But here I am getting SocketException during binding at 2nd iteration. 

If any one having any idea or solution, then please share here.
