C# 下载后的错误文本文件

当我尝试下载文本文件时，我会收到像ěěË˨TÁs

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20120601.prn没有问题。

怎么回事？

你需要这样的东西

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

---

你需要这样的东西

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

---

将编码设置为UTF8

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

---

将编码设置为UTF8

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

基本上，您必须启用webclient的自动解压缩。例如，如果使用文件20120601.prn的firebug或fiddler检查响应标头，则返回gzip内容编码。对于文件20120603.prn，完全缺少内容编码头

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; 
    } 
}

20120603.prn中是否只有英文字母？20120603.prn中是否只有英文字母？如果我没有弄错，您的编码将是ISO8859-2如果我没有弄错，您的编码将是ISO8859-2
