C＃可以按路径打开特定文件的容器文件夹吗？

Question

In my project, I have a fileupload control for user to upload their document and I want to provide a link to user to open their files.

steps: after user upload a file, my web will create a link for it when user click on that link, the container folder of that file will open.

For example, a file which its path is C:\\Users\\John\\Downloads\\jpg\\a.jpg uploaded to the fileupload control. when user click on the link of that file, a folder C:\\Users\\John\\Downloads\\jpg will be opened.

To get the file path:

string filePath = FileUpload1.PostedFile.FileName; // file name with path.

So, how can I open a folder in client PC by C#?

Answer 1

For security reasons, browsers do not expose the local filesystem to the Javascript sandbox . What you're asking is not possible with Javascript or any other common browser technology that does not require a client install (like Flash or ActiveX). You definitely cannot get it in c# which runs on the server and has no knowledge of the client's filesystem.
