Question

注意：我自己解决了这个问题。见下面的答案。

我正在使用 ZipStorer 来压缩ASP.NET C＃4.0 WebForm中的文件。

在MemoryStream中创建Zip并使用httpResponse传输后，客户端用户无法将文件作为Zip文件打开。

任何提示？谢谢。

以下是我的代码：

string text = GetLongText();
byte[] ba = Encoding.UTF8.GetBytes(text);
using (MemoryStream ms = new MemoryStream())
{
    using (ZipStorer zip = ZipStorer.Create(ms, "My Zip File"))
    {
        zip.AddStream(ZipStorer.Compression.Deflate, "MyText.txt", new MemoryStream(ba), DateTime.Now, "My Text");

        Response.Clear();
        Response.AppendHeader("content-disposition", "attachment; filename=MyZip.zip");
        Response.ContentType = "application/zip";
        ms.WriteTo(Response.OutputStream);
        Response.End();
    }
}

    Response.ContentType = "application/zip";
    Response.BinaryWrite(ms.ToArray());
    Response.End();
}
}

ZipStorer - MemoryStream中的Zip文本，通过httpResponse传输，无法作为Zip文件打开
