C# ip hash算法实现ip分流

            var ip = textBox5.Text;
            var iphashcode = ip.GetHashCode();

            if (iphashcode < 0) iphashcode = -iphashcode;

            int serverPos = iphashcode % serverListSize;
            
            textBox6.AppendText(proxyIpNodes[serverPos+1]+ System.Environment.NewLine);
