我有一個asp.net應用程序和頁面上傳文件（csv文件）。在這個頁面我有一個updatepanel，我有一個html文件上傳控件。
fileupload在IE和Firefox中均可正常工作。使用chrome，我可以看到PostedFile.Filename =「bac.csv」， PostedFile.InputStream.Length = 80 但是當我將InputStream複製到一個字節數組時，所有的字節都有零值。請記住，與其他瀏覽器相同的代碼也能正常工作。html文件上傳控件沒有在Chrome上傳文件

提琴手也顯示不同的postdata。請參閱下面有關我在Fiddler中看到的Chrome和Firefox數據。顯然，Chrome並未發佈文件數據。我做錯了什麼，我該如何解決它。

我想提供有關此問題的更多信息。我觀察到，僅當IIS安全性設置爲「Windows身份驗證」時會發生這種情況。如果我啓用「匿名身份驗證」或兩者都可以正常工作。我無法爲此網頁啓用「匿名身份驗證」。 – user738338

我與Windows身份驗證具有完全相同的問題。不幸的是，我不得不爲這個應用程序使用Windows身份驗證。 – Ryan

我們有完全相同的行爲（只包含NUL值JPEG文件）我們使用的是IIS Web服務器使用Windows身份驗證和Chrome 19.0.1084.46 。據介紹週二當谷歌更新的鉻..

現在我們恢復了使用MSIE9
