C# KeepAlive的设置

  C# KeepAlive的相关设置

网上有很多相关KeepAlive的内容，终于找到了有关C#的这方面资料，设置了下，有行可靠！

 TcpListener myListener = new TcpListener(IPAddress.Any, port);//绑定端口IP信息
 
 myListener.Start();//开始监听

 TcpClient newClient=myListener.AcceptTcpClient();//接受请求

 newClient.Client.IOControl(IOControlCode.KeepAliveValues, KeepAlive(1, 30000, 10000), null);//设置Keep-Alive参数

 private byte[] KeepAlive(int onOff, int keepAliveTime, int keepAliveInterval)
 {
     byte[] buffer = new byte[12];
     BitConverter.GetBytes(onOff).CopyTo(buffer, 0);
     BitConverter.GetBytes(keepAliveTime).CopyTo(buffer, 4);
     BitConverter.GetBytes(keepAliveInterval).CopyTo(buffer, 8);
     return buffer;
  }

KeepAlive函数参数说明:

onOff:是否开启KeepAlive

keepAliveTime:开始首次KeepAlive探测前的TCP空闭时间


keepAliveInterval: 两次KeepAlive探测间的时间间隔


Keep-Alive的位置我是放在收到客户端以后，对每个连入的客户端都设置一次。
