1、客户最近提出一个需求，要在WEB上远程管理客户端软件。那我们就仿路由器那种模式用SOCKET来解决吧。做了个DEMO，本机测试OK，拿到别的机器上做服务器，提示由于目标机器积极拒绝，无法连接。查询各种资料，有的说是端口没开，有的说是服务没开。各种雾水啊！仔细一想，问题可能出在本机在局域网IP上，而不是用127.0.0.1。更正代码后，问题解决。下面演示服务器端代码的关键部分。protected void Listen() MessageBox.Show(start listening); string ip = ; System.Net.IPHostEntry IpEntry = System
2、.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName(); for (int i = 0; i != IpEntry.AddressList.Length; i+) if (!IpEntry.AddressListi.IsIPv6LinkLocal) ip= IpEntry.AddressListi.ToString(); IPEndPoint ipend = new IPEndPoint(IPAddress.Parse(ip), 8000); Socket sc = new Socket(AddressFamily.InterNetwork, So
3、cketType.Stream, ProtocolType.Tcp); sc.Bind(ipend); Socket acc; while (true) sc.Listen(1); acc= sc.Accept(); byte buff = new byte1024; int recbyte = acc.Receive(buff, buff.Length, 0); if (recbyte = 0) break; string reciveval = ; reciveval += Encoding.GetEncoding(gb2312).GetString(buff, 0, recbyte);
4、string returnval = 开始升级; byte returnBy = Encoding.GetEncoding(gb2312).GetBytes(returnval); acc.Send(returnBy, returnBy.Length, 0); acc.Close(); sc.Close(); public string sendMessage() IPEndPoint ipend = new IPEndPoint(IPAddress.Parse(192.168.XXX.XXX),8000); Socket sc = new Socket(AddressFamily.Inter
5、Network,SocketType.Stream,ProtocolType.Tcp); sc.Connect(ipend); string message = 请升级软件; byte bt = Encoding.GetEncoding(gb2312).GetBytes(message); sc.Send(bt,bt.Length,0); byte rebuff = new byte1024; int recive = sc.Receive(rebuff, rebuff.Length, 0); string returnval = ; returnval += Encoding.GetEncoding(gb2312).GetString(rebuff, 0, recive); sc.Close(); return returnval;
