Question

我正在尝试将图像上传到我的IIS 7服务器，但它已经损坏了。相同的代码通过Visual Studio在本地实例上运行。

本地标题：

以下是上传表单调用的上传方法：

[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");
}

如果相关，我使用此File Uploader

图像作为所有NUL字节在远程服务器上出现。任何帮助表示赞赏。
