WebClient.DownloadString结果与Browser结果不匹配2 [英] WebClient.DownloadString result is not match with Browser result 2

问题描述

以下代码：

  WebClient wc = new WebClient（）; 
 wc.Encoding = Encoding.UTF8; 
 string Url =http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64; 
 return wc.DownloadString（Url）; 
  

代码返回：

                                                                      H9Ȓ J ^  j  T Q=HH 'Qm       1 hF 4 *       { x \o？
 / b 
 
 $ b 
当我在任何网页浏览器中访问该网址时，我得到：
  12：29：45，A，3540,3567,3600,3621,3690,3515,140,​​238204,849582597,1,20140914,122945 ;; @ @ 2825 @ 3523 @ 3583 @ 1700 @ 1,1 @ 2000 @ 3522 @ 3600 @ 8700 @ 2,1 @ 500 @ 3511 @ 3640 @ 2500 @ 1;; 19774,99736,1 
  / pre> 
 
 
有没有办法得到正确的字符串？
 
 
 
还有，我使用这个在线解码器，但我没有得到正确答案：
  
  async void Main（） 
 {
 using（var handler = new HttpClientHandler（））
 {
 handler.AutomaticDecompression = DecompressionMethods.GZip; 
使用（HttpClient client = new HttpClient（handler））
 {
 var result = await client.GetStringAsync（http://www.tsetmc.com/tsev2/data/instinfodata.aspx ？I = 59266699437480384和C = 64\" ）; 
 result.Dump（）; 
} 
} 
} 
  
 
The following code:
WebClient wc = new WebClient();
wc.Encoding = Encoding.UTF8;
string Url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64";
return wc.DownloadString(Url);
code returns:
�Q�T�MP�J�A|�^D����~���C�"�����l� ��;I&3=j=�iG�H9Ȓ�J�^� �j��T�Q=HH�'Qm�������1�hF�4�*�������{�x�\o?
when I visit that URL in any web browser, I get:
12:29:45,A ,3540,3567,3600,3621,3690,3515,140,238204,849582597,1,20140914,122945;;1@2825@3523@3583@1700@1,1@2000@3522@3600@8700@2,1@500@3511@3640@2500@1,;19774,99736,1
is there any way to get right string?

also, I use this online Decoder, but I don't get right answer:
Universal Online Decoder
解决方案
In Linqpad you can run the below code, variation from Webclient.  As you can see from the picture, its due to the Gzip compression which browser automatically handles.
 
async void Main()
{
    using (var handler = new HttpClientHandler())
    {
        handler.AutomaticDecompression = DecompressionMethods.GZip;
        using (HttpClient client = new HttpClient(handler))
        {
            var result = await client.GetStringAsync("http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64");
            result.Dump();
        }
    }
}
