上传时没有破坏文件

我正在尝试将图像上传到我的IIS 7服务器，但它出现损坏。相同的代码通过Visual Studio在本地实例上工作。上传时没有破坏文件

这是我上传的方法是通过上传表单称为：

[HttpPost] 
public ActionResult UploadPhoto(object qqfile) 
{ 
    // Get current logged in user 
    var currentUser = _staffRepository.StaffMembers.First(p => p.Login == User.Identity.Name.Replace("Domain\\", "")); 

    var length = Request.ContentLength; 
    var bytes = new byte[length]; 
    Request.InputStream.Read(bytes, 0, length); 
    // bytes has byte content here. what do do next? 

    var fileName = currentUser.Login + ".jpg"; 

    var saveToFileLoc = string.Format("{0}\\{1}", 
            Server.MapPath("~/App_Data/uploads"), 
            fileName); 

    // save the file. 
    var fileStream = new FileStream(saveToFileLoc, FileMode.Create, FileAccess.ReadWrite); 
    fileStream.Write(bytes, 0, length); 
    fileStream.Close(); 

    return new RedirectResult("MyProfile"); 
}

如果是相关的，我使用这个File Uploader

图像在远程服务器上以所有NUL字节出现。任何援助表示赞赏。

这似乎这是使用Chrome 20开发浏览器有问题。最新的Firefox和IE 9似乎这样做很好。我正在进一步调查。 – joshschreuder
