DotNetZip 异常错误状态（无效 literal/length 代码）

Question

NET MVC 4 应用程序，在此应用程序中，我必须下载 Zip 文件中由字节数组列表表示的多个文件，因此我使用了 DotNetZip 库。当我执行这段代码时：

 using (MemoryStream ms = new MemoryStream())
       {
        using (var archive = new ZipFile())
        {
         foreach (var item in byteArrays)
         {
          var entry = archive.AddEntry("file" + i + ".pdf", item);
          i++;
          archive.Save("All.zip");
           using (var zipStream = entry.OpenReader())
           {
           zipStream.Write(item, 0, item.Length);
          }
         }
        }
        return File(ms.ToArray(), "application/zip", "all.zip");
        }

在这一行：

zipStream.Write(item, 0, item.Length);

我遇到了这个错误：

您不需要调用 zipStream.Write，因为您已经在 .AddEntry 调用中传递了数据。

这对我有用：

var i = 1;

using (var outStream = new MemoryStream())
{
    using (var archive = new ZipFile())
    {
        foreach (var item in byteArrays)
        {
            using (MemoryStream ms = new MemoryStream(item))
            {
                var entry = archive.AddEntry($"file{i++}.pdf", ms);
                archive.Save(outStream);
            }
        }
    }
    outStream.Position = 0;
    return File(outStream.ToArray(), "application/zip", "all.zip");
}
