C#简单实现发送socket字符串

private void button1_Click(object sender, EventArgs e)    {      String string1 = "测试数据123测试数据ABC";      byte[] buffer = new byte[2048];      buffer = Encoding.Default.GetBytes(string1);      Socket socket = new Socket(AddressFamily.InterNetwork,        SocketType.Stream, ProtocolType.Tcp);      socket.Connect("10.2.3.101", 9100);      socket.Send(buffer);      socket.Close();      MessageBox.Show("发送完毕");    }

using System.Net.Sockets;
