保存文件时出现UnauthorizedAccessException，但可以创建目录

我正在尝试将文件保存到磁盘，但出现UnauthorizedAccessException. 该错误表明我必须获得该文件夹的正确权限，并且我已经尝试了所有可能找到的用户，但是它不起作用.

I'm trying to save a file to the disk but I get UnauthorizedAccessException. The error says I have to get the right permissions on the folder, and I've tried every possible user I can find but it doesn't work.

尝试了以下用户

• 网络
• 网络服务
• IUSR
• IUSR_ [计算机名]

并赋予了其全部权利，而它却无法正常工作.

And given the full rights without it working.

我真正感到奇怪的是，我在尝试保存文件之前创建了一个目录，并且效果很好，这是在尝试将文件保存到新目录时，我得到了UnautorhizedAccessException.

What I find really strange is that I create a directory before I try to save the file and that works perfectly, it's when trying to save a file to that new directory that I get the UnautorhizedAccessException.

代码如下:

[HttpPost] public ActionResult Images(HttpPostedFileBase file, string boatId) { if (file.ContentLength > 0) { var fileName = Path.GetFileName(file.FileName); var path = Path.Combine(Server.MapPath("~/Content/Images/" + boatId)); Directory.CreateDirectory(path); file.SaveAs(path); } return View($"Filen på {boatId} har laddats upp"); }

对我缺少的东西有什么想法吗?

Any ideas at what I'm missing?

推荐答案

结果是我要保存的是文件夹而不是文件，我忘记了将fileName与路径结合起来.

Turns out what I was trying to do was saving the folder and not the file, I forgot to combine the fileName with the path.

将保存"部分更改为以下内容:

Changed the Save part to the following:

file.SaveAs(Path.Combine(path, fileName));

谁为我解决了整个问题.

Which solved the whole thing for me.
