html fileupload控件不会在Chrome中上传文件

标签： google-chrome file-upload

我有一个带有上传文件页面的asp.net应用程序（csv文件）。在这个页面中，我有一个更新面板，我有一个html文件上传控件 fileupload适用于IE和Firefox。使用chrome，我可以看到PostedFile.Filename =“bac.csv”， PostedFile.InputStream.Length = 80 但是当我将Inputstream复制到一个字节数组时，所有字节的值都为零。请记住，相同的代码适用于其他浏览器。

Fiddler也展示了不同的postdata。请参阅下面我在Fiddler中看到的Chrome和Firefox数据。显然，Chrome并未发布文件数据。我做错了什么，如何解决它。
