我正在尝试将文件保存到磁盘，但出现 UnauthorizedAccessException.错误提示我必须获得对该文件夹的正确权限，并且我已经尝试了我能找到的所有可能的用户，但它不起作用.

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]

并在没有它的情况下获得全部权利.

And given the full rights without it working.

我发现真正奇怪的是，我在尝试保存文件之前创建了一个目录，并且效果很好，当我尝试将文件保存到该新目录时，我收到了 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

结果我试图做的是保存文件夹而不是文件，我忘记将文件名与路径结合起来.

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));

这为我解决了整个问题.

Which solved the whole thing for me.
