using System;
using System.Net;

class Program
{
    static void Main()
    {
        string url = "https://example.com"; // 替换为你要请求的URL

        try
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "GET";

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                HttpStatusCode statusCode = response.StatusCode;
                int numericStatusCode = (int)statusCode;

                Console.WriteLine("HTTP状态码: " + numericStatusCode);
            }
        }
        catch (WebException ex)
        {
            if (ex.Response is HttpWebResponse errorResponse)
            {
                HttpStatusCode statusCode = errorResponse.StatusCode;
                int numericStatusCode = (int)statusCode;

                Console.WriteLine("HTTP状态码: " + numericStatusCode);
            }
