【求助】客户端发送数据 服务端如何提取
客户端 发送的数据

C# code

 netstream.Write(new byte[] { 0, 4 }, 0, 2);                    netstream.Write(Encoding.Unicode.GetBytes(user_tb.Text), 0, Encoding.Unicode.GetBytes(user_tb.Text).Length);                    netstream. Write(Encoding.Unicode.GetBytes(mima_t.Text), 0, Encoding.Unicode.GetBytes(mima_t.Text).Length);

服务端如何提取？分别提取就可以了
我写的是这样，但是不对

C# code

         private string DecodingBytes(byte[] s)        {            return string.Concat(s[0].ToString(), s[1].ToString());//接受第一个数据包。                    byte[] _cmdBuff = new byte[128];                    clientSkt.Receive(_cmdBuff);                    string _cmd = DecodingBytes(_cmdBuff);  switch (_cmd)                    {case "04":                            {                                                                                                                                                                    string nam = Encoding.Unicode.GetString(_cmdBuff).TrimEnd('\0');//想提取客户端发来的user_tb.Text string _mima = Encoding.Unicode.GetString(_cmdBuff).TrimEnd('\0');//想提取mima_t.Text  }}

后面的提取有些问题，正确的格式应该是什么？

[解决办法]

C# code

// 编码发送netstream.Write(new byte[] { 0, 4 }, 0, 2);byte[] usrarr = Encoding.UTF8.GetBytes(user_tb.Text);netstream.Write(usrarr, 0, usrarr.Length);netstream.Write(new byte[] { 0, 1 }, 0, 1);byte[] mimaarr = Encoding.UTF8.GetBytes(mima_t.Text);netstream.Write(mimaarr, 0, mimaarr.Length);// 接收解码byte[] _cmdBuff = new byte[128];clientSkt.Receive(_cmdBuff);string _cmd = Encoding.UTF8.GetString(_cmdBuff, 0, 2);switch (_cmd){    case "04":        {            string[] arr = Encoding.UTF8.GetString(_cmdBuff, 2, _cmdBuff.Length - 2).TrimEnd('\0').Split('\0');            string user = arr[0];//想提取客户端发来的user_tb.Text            string mima = arr[1];//想提取mima_t.Text             break;        }    default:        break;}Unicode 不好处理，用 UTF8 编码
