如何为所有类型的URL（无论是HTTPS还是HTTP或WWW）创建Web请求并获取其html作为响应？

Question

我必须输入www.xyz.ki.com类型的URL的html内容

> I tried this code

using System;
using System.IO;
using System.Net;
class program{
static void Main(string[] args)
{
    List<string> paths = new List<string>() 
      {"https://www.sbi.co.in/careers/ongoing-recruitment.html",
      "www.csd.bih.nic.in/Notification.htm"};
    foreach (var links in paths)
    {
        System.Console.WriteLine("..operating on   :  {0}",links);
        WebRequest request = WebRequest.Create(links);
    WebResponse response = request.GetResponse();
    Stream dataStream = response.GetResponseStream();
    StreamReader reader = new StreamReader(dataStream);
    string responseFromServer = reader.ReadToEnd();
    System.Console.WriteLine(responseFromServer);
    }

  }
}

它仅对第一个URL有效，但是当控制权传递给第二个URL时，它会给出错误
