C# KeepAlive的相关设置
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。
