是否有一种简单的方法来读取外部网页的源代码？ASP.NET

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

namespace ReadWebPageSourceCode
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "https://www.example.com";
            string sourceCode = GetWebPageSourceCode(url);
            Console.WriteLine(sourceCode);
        }

        static string GetWebPageSourceCode(string url)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "GET";
            request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3";
            request.Timeout = 10000;
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream stream = response.GetResponseStream();
            StreamReader reader = new StreamReader(stream, Encoding.UTF8);
            string sourceCode = reader.ReadToEnd();
            reader.Close();
            stream.Close();
            response.Close();
            return sourceCode;
        }
    }
}
