如何在C#/ ASP.NET中读取HttpResponse对象的主体内容？

using System;
using System.IO;
using System.Net;

public class Program
{
    public static void Main()
    {
        // 创建一个Web请求
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://example.com");
        
        // 发送请求并获取响应
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        
        // 读取响应的主体内容
        using (Stream stream = response.GetResponseStream())
        {
            using (StreamReader reader = new StreamReader(stream))
            {
                string body = reader.ReadToEnd();
                Console.WriteLine(body);
            }
        }
        
        // 关闭响应对象
        response.Close();
    }
}
