将 Stream 从存档中的文件转换为 Byte[]

Question

在 Net Core 2.1 上，我试图从 ZIP 存档中读取文件。

我需要将每个文件内容转换为 Byte[] 所以我有：

using (ZipArchive archive = ZipFile.OpenRead("Archive.zip")) {

  foreach (ZipArchiveEntry entry in archive.Entries) {

    using (Stream stream = entry.Open()) {

      Byte[] file = new Byte[stream.Length];

      stream.Read(file, 0, (Int32)stream.Length);

    }

  }

}

当我运行它时，我收到错误：

Exception has occurred: CLR/System.NotSupportedException
An exception of type 'System.NotSupportedException' occurred in System.IO.Compression.dll but was not handled in user code: 
'This operation is not supported.' at System.IO.Compression.DeflateStream.get_Length()

如何将每个文件的内容放入 Byte[] 中？

尝试做这样的事情：

using (ZipArchive archive = ZipFile.OpenRead("archieve.zip")) 
{

   foreach (ZipArchiveEntry entry in archive.Entries) 
   {
      using (Stream stream = entry.Open()) 
      {
         byte[] bytes;
         using (var ms = new MemoryStream()) 
         {
            stream.CopyTo(ms);
            bytes = ms.ToArray();
         }
      }
   }
}
