我有一个带有上传文件(csv 文件)页面的 asp.net 应用程序。在此页面中，我有一个更新面板，因为我有一个 html 文件上传控件。
文件上传适用于 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 复制到字节数组时，所有字节的值为零。请记住，同样的代码可以在其他浏览器上正常工作。
Fiddler 还显示不同的 postdata。有关我在 Fiddler 中看到的 Chrome 和 Firefox 数据，请参见下文。显然，Chrome 没有发布文件数据。我做错了什么，我该如何解决。

这是 Chrome 19.0.1084.46 中的一个已知问题。参见 http://code.google.com/p/chromium/issues/detail?id=128574
关于google-chrome - html 文件上传控件不会在 Chrome 中上传文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10639730/
