Question

当我尝试下载文本文件时，会收到"úěćË¨Të€Ás…žVż$—éxś¶źŹßCb}ă¬–92á•,˝V....."

等错误文字

我使用WebClient类：

private void button1_Click(object sender, EventArgs e)
{
    WebClient _WebClient = new WebClient();
    string url = "http://bossa.pl/pub/metastock/forex/sesjafx/";
    string file= "20120601.prn";
    _WebClient.DownloadFile(url + file, @"C:\"+file);
}

文件20120603.prn没有问题，但是20120601.prn是。怎么回事？

Answer 1

你需要这样的东西

client.Encoding = Encoding.GetEncoding("your encoding");

Answer 2

重复Automatically decompress gzip response via WebClient.DownloadData

基本上你必须启用webclient的自动解压缩。如果您检查文件20120601.prn的响应标头（例如，使用firebug或fiddler），则返回gzip内容编码。对于文件20120603.prn，根本没有Content-Encoding标头。

void Main()
{
    WebClient _WebClient = new MyWebClient(); 
    string url = "http://bossa.pl/pub/metastock/forex/sesjafx/"; 
    string file= "20120601.prn";
    string a = _WebClient.DownloadString(url + file); 
}

class MyWebClient : WebClient 
{ 
    protected override WebRequest GetWebRequest(Uri address) 
    { 
        HttpWebRequest request = base.GetWebRequest(address) as HttpWebRequest; 
        request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip; 
        return request; 
    } 
}

Answer 3

将您的编码设置为UTF8

_WebClient.Encoding = System.Text.Encoding.UTF8;

下载后文本文件错误
