                VerServer = trServer.ReadLine();
                trServer.Close();

                System.IO.TextReader trClient = new System.IO.StreamReader(@"C:\PRP
\VersionClient.txt");
                VerClient = trClient.ReadLine();
                trClient.Close();

                if(VerServer!=VerClient)
