在C#中通过url获取页面HTML文档

这个简单直接上代码:

using System;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        Console.WriteLine("输入url地址：");
        string url = Console.ReadLine(); 
        using (HttpClient client = new HttpClient())
        {
            try
            {
                HttpResponseMessage response = await client.GetAsync(url);
                string content = await response.Content.ReadAsStringAsync();
                Console.WriteLine(content);
            }
            catch (HttpRequestException HRex)
            {
                Console.WriteLine("请求失败： " + HRex.Message);
            }
            catch (Exception ex) 
            {
                Console.WriteLine("请求失败：" + ex.Message);
            }
        }
        Console.ReadLine(); 
    }
}

你猜的没错，这篇就是凑数的
