如何通过c#检查我的站点是否可靠

using System;
using System.Net;

class Program
{
    static void Main(string[] args)
    {
        string url = "https://www.example.com"; // 要检查的站点地址

        try
        {
            // 创建HTTP请求对象
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "HEAD"; // 设置请求方法为HEAD

            // 发送请求并获取响应对象
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            // 检查响应的状态码
            if (response.StatusCode == HttpStatusCode.OK || response.StatusCode == HttpStatusCode.MovedPermanently)
            {
                Console.WriteLine("站点可靠");
            }
            else
            {
                Console.WriteLine("站点存在问题");
            }

            response.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine("检查站点时发生异常：" + ex.Message);
        }
    }
}
