[Solved] Unable to listen to Data received using C# Synchronous Socket programming.

Socket [] sockets=new Socket[10];

for (int socketnumber=0;socketnumber<10;socketnumber++)
{
    for( int i=startport;i<endport;i++)>
   {
       IPEndpoint remote_endpoint; // Some Server
       remote_endpoint.Port = i; //Only Port is different on server
       sockets[socketnumber].Connect(remote_endpoint );
       Thread.Sleep(10);
       sockets[socketnumber].Send(packet1);
       Thread.Sleep(10)
       sockets[socketnumber].Receive(packet2);//I get a crash here up till //socket number ==9. Only socketnumber=9 works i.e the last socket.
