用路径检查我的本地 ip 是否有效

Question

您好，我尝试检查我的 ip（在本地服务器上）是否有效并为其添加路径，但问题是当我测试“192.168.0.235/cmd”时它不被视为 ip 地址.html?c-31" 很好地显示在我的浏览器上。这是代码：

public static bool check_ip(string ip)
{
    //192.168.0.235/cmd.html?c=31
    string path_ip = ip + "/cmd.html?c=31"; // error not an ip
    Ping ping = new Ping();
    IPAddress address = IPAddress.Parse("path_ip");
    PingReply pong = ping.Send(address, 100);
    if (pong.Status == IPStatus.Success)
    {
        return true;
    }
    return false;
}

如何让我的函数检查带有路径的 ip（例如：“192.168.0.235/cmd.html?c-31”）？

您应该只检查 ip 部分：

        public static bool check_ip(string ip)
        {
                //192.168.0.235/cmd.html?c=31
                string path_ip = ip + "/cmd.html?c=31"; // error not an ip
                Ping ping = new Ping();
                IPAddress address = IPAddress.Parse(ip);
                PingReply pong = ping.Send(address, 100);
                if (pong.Status == IPStatus.Success)
                {
                    return true;
                }
                return false;
        }

注意这样的行：

// "path_ip" is not the value of your variable, but a string value "path_ip"
IPAddress address = IPAddress.Parse("path_ip");

如果您想像浏览器一样检查 url：

using var client = new HttpClient();

var result = await client.GetAsync("http://192.168.0.235/cmd.html?c=31");
Console.WriteLine(result.StatusCode); // if the status code is in the 2XX range, you are ok.
