我试图代码之一variouse以下。icant尚未通过telnet进行连接平安系统
static void Main(string[] args)

// connected to the same address as specified by the server, port
// combination.

stream = client.GetStream();
data = new Byte[256];
// String to store the response ASCII representation.
String responseData = String.Empty;
// Read the first batch of the TcpServer response bytes.
Int32 bytes = stream.Read(data, 0, data.Length);
responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
Console.WriteLine("Received: {0}", responseData);
string message = Console.ReadLine();

// Get a client stream for reading and writing.
