I think I found the syntax for the finally block, but it will not compile

try
{
  // some code
  IPEndPoint ipEP = new IPEndPoint(paraIPAddress, iPort);
  Socket udpSocket = new Socket(ipEP.Address.AddressFamily,SocketType.Dgram,ProtocolType.Udp);
  // some more code
}
catch(Exception ex)
{
  //Do something if exception is thrown
}
finally
{
  if (udpSocket != null)
  {
    udpSocket.Close();
  }
}

This code gives me the error that udpSocket does not exist in the namespace, so I moved the declaration statement outside the try..catch..finally block.

Socket udpSocket;
try
{
  // some code
  IPEndPoint ipEP = new IPEndPoint(paraIPAddress, iPort);
  udpSocket = new Socket(ipEP.Address.AddressFamily,SocketType.Dgram,ProtocolType.Udp);
  // some more code
}
catch(Exception ex)
{
  //Do something if exception is thrown
}
finally
{
  if (udpSocket != null)
  {
    udpSocket.Close();
  }
}

Now this code gives me the compile error use of unassigned local variable udpSocket

Any hints or comments welcome.

Thanks,
