Question

我正在尝试使用以下代码从HttpWebResponse对象中解压缩并读取文件：

using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
using (MemoryStream ms = new MemoryStream())
{
    response.GetResponseStream().CopyTo(ms);
    ms.Seek(0, SeekOrigin.Begin);

    using (ZipArchive za = new ZipArchive(ms, ZipArchiveMode.Read))
    {
        foreach (ZipArchiveEntry zae in za.Entries)
        {
            using (StreamReader sr = new StreamReader(zae.Open(), Encoding.GetEncoding(1251), true, 2 << 18))
            {
                Console.WriteLine(sr.ReadLine());
            }
        }
    }
}

但获得System.IO.InvalidDataException: End of Central Directory record could not be found。我在做什么错了？

这是我在使用GZipStream时的想法（仅作为示例，此处不能保证）...

using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
using (GZipStream gzipStream = new GZipStream(response.GetResponseStream(), CompressionMode.Decompress))
using (StreamReader sr = new StreamReader(gzipStream))
{
    Console.Write(sr.ReadToEnd());
}

C＃解压缩并从HttpWebResponse中读取文件
