如何檢查服務器是否正在接受連接

Question

我只想檢查smpp服務器是否正在接受連接。我們可以使用命令提示符下使用以下命令來檢查：telnet 152.26.53.39 2775我只是想用C＃編寫此命令

Answer 1

TcpClient tcpClient = new TcpClient(); 
     try 
      { 
       tcpClient.Connect("152.26.53.39", 2775); 
       Console.WriteLine("Port 2775 Open"); 
      } 
     catch (Exception){ 

       Console.WriteLine("Port 2775 Closed"); 
     } 

Answer 2

您可以如下使用Ping class：

string nameOrAddress="152.26.53.39 2775"; 
public static bool PingHost(string nameOrAddress) 
{ 
    bool pingable = false; 
    Ping pinger = new Ping(); 

    try 
    { 
     PingReply reply = pinger.Send(nameOrAddress); 

     pingable = reply.Status == IPStatus.Success; 
    } 
    catch (PingException) 
    { 
     // Discard PingExceptions and return false; 
    } 

    return pingable; 
}
