当要求用gzip COM pression我得到了很多的以下错误页面：

System.IO.InvalidDataException：本   CRC采用gzip页脚不匹配   CRC从DECOM pressed计算   数据

我使用本地GZipStream到DECOM preSS和期待在处理这个。考虑到这一点是有一个变通解决此或其他的GZip库（免费的吗？），它会处理这个问题的正确？

我核实WebResponse的ContentEncoding是GZIP

更新5/11 简化的这段

  //来电
公共无效SOSampleGet（字符串URL）
{
    //初始化的WebRequest。
    的WebRequest =（HttpWebRequest的）WebRequest.Create（URL）;
    webRequest.Method = WebRequestMethods.Http.Get;
    webRequest.KeepAlive = TRUE;
    webRequest.Accept =text / html的，是application / xhtml + xml的，应用程序/ XML; Q = 0.9，* / *; Q = 0.8;
    webRequest.Headers.Add（接受编码，GZIP，放气）;
    webRequest.Referer = WebUtil.GetDomain（URL）;

    HttpWebResponse WebResponse类=（HttpWebResponse）webRequest.GetResponse（）;

    使用（流流= GetStreamForResponse（WebResponse类，READTIMEOUT_C​​ONST））
    {
        //使用流
    }
}

//方法
私有静态流GetStreamForResponse（HttpWebResponse WebResponse类，INT readTimeOut）
{
    流流;
    开关（webResponse.ContentEncoding.ToUpperInvariant（））
    {
        案GZIP：
            流=新GZipStream（webResponse.GetResponseStream（），玉米pressionMode.Decom preSS）;
            打破;
        情况下使用deflate：
            流=新DeflateStream（webResponse.GetResponseStream（），玉米pressionMode.Decom preSS）;
            打破;

        默认：
            流= webResponse.GetResponseStream（）;
            stream.ReadTimeout = readTimeOut;
            打破;
        }
    返回流;
}
 

解决方案

怎么样的WebRequest AutomaticDecom pression房产可用，因为.NET 2？只需添加：

  webRequest.AutomaticDecom pression = DECOM pressionMethods.GZip | DECOM pressionMethods.Deflate;
 

这也增加了gzip的，紧缩的接受编码头。

When requesting a page with Gzip compression I am getting a lot of the following errors:

System.IO.InvalidDataException: The CRC in GZip footer does not match the CRC calculated from the decompressed data

I am using native GZipStream to decompress and am looking at addressing this. With that in mind is there a work around for addressing this or another GZip library (free?) which will handle this issue properly?

I am verifying the webResponse ContentEncoding is GZIP

Update 5/11 A simplified snippit

//Caller
public void SOSampleGet(string url) 
{
    // Initialize the WebRequest.
    webRequest = (HttpWebRequest)WebRequest.Create(url);
    webRequest.Method = WebRequestMethods.Http.Get;
    webRequest.KeepAlive = true;
    webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
    webRequest.Headers.Add("Accept-Encoding", "gzip,deflate");
    webRequest.Referer = WebUtil.GetDomain(url);

    HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();    

    using (Stream stream = GetStreamForResponse(webResponse, READTIMEOUT_CONST))
    {
        //use stream
    }
}

//Method
private static Stream GetStreamForResponse(HttpWebResponse webResponse, int readTimeOut)
{
    Stream stream;
    switch (webResponse.ContentEncoding.ToUpperInvariant())
    {
        case "GZIP":
            stream = new GZipStream(webResponse.GetResponseStream(), CompressionMode.Decompress);
            break;
        case "DEFLATE":
            stream = new DeflateStream(webResponse.GetResponseStream(), CompressionMode.Decompress);
            break;

        default:
            stream = webResponse.GetResponseStream();
            stream.ReadTimeout = readTimeOut;
            break;
        }    
    return stream;
}

What about the webrequest AutomaticDecompression Property available since .net 2? Simply add:

webRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

It also adds the gzip,deflate to the accept encoding header.
