您不能以流的形式读取和写入Excel文件，它们具有自己的结构.

走开，研究一下我昨天给您的链接，甚至还有一篇CodeProject文章，它将确切地告诉您如何开始.

You cannot read and write Excel files as streams, they have a structure of their own.

Go away and study the links I gave you yesterday, there is even a CodeProject article that will show you exactly how to get started.
