C#用WebClient访问网站被拒绝,怪事了？

Question

用WebClient访问任何网址都提示这个错误，奇怪了，我看别人都用的好好了。

Answer 1

WebClient wc = new WebClient();
string str = wc.DownloadString("https://www.baidu.com/");

改为https试试呢
或者使用：HttpClient

using System.Net.Http;

static async Task Main(string[] args)
{
    HttpClient client = new HttpClient();
    string str = await client.GetStringAsync("https://www.baidu.com/");
    Console.WriteLine(str);
}
