Is there a .net method to convert a file path to a virual file path?

Example:

C:/somefile.pdf
convert to:
https://www.mysite.forms/somefile.pdf

Thank you

What do you you mean by convert?  is the file outside of the website?  If that is the case, you would use file system object http://msdn.microsoft.com/en-us/library/aa711216(v=vs.71).aspx  and copy the file to a folder inside of your webroot.

Can you explain the situation?

There is Server.MapPath which basically does the opposite of what you want but I have not seen a function for what you need.

I want the site to serve up a file based on a file structure.

I can't explicitly embed a link as files change daily. I need the site to read the file structure. Similar to FileZilla.

Do you not know even the root folder path?

One option is to have a page which reads the file from disk and writes to client.

I am using a treeview and emulating the structure just fine. My problem is the file itself. I have a directory in which FTP users write to a modify all the time. So even though I have a root there can be multiple levels to the file itself.

I was hoping to us NavigateURL of the treeview and that's where I need the virtual path.

>I need the virtual path.

Virtual path is under the site directory. If this root of treeview is under your site path, you can get list of files and directories and construct the virtual path.

I do this on multiple sites.  All the file live in a folder c:\root\sites\website.com\files  and you want to list each file in the the files folder and display them to the site as a link.


http://www.4guysfromrolla.com/webtech/faq/FileSystemObject/faq5.shtml

This is in classic asp but I believe you can use fso in .net

im objFSO
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")

'Get the folder object associated with the directory
Dim objFolder
Set objFolder = objFSO.GetFolder("c:\root\sites\website.com\files")

'Loop through the Files collection
Dim objFile
For Each objFile in objFolder.Files
 Response.Write  "<a href=""/files/"&objFile.Name &""">"&objFile.Name &"</a>""
Next

'Clean up!
Set objFolder = Nothing
Set objFile = Nothing
Set objFSO = Nothing

Open in new window

Codecruiser,
Yea it looks like I'll have to do some 'string-smithing' to get what I want. Was hoping for a more elegant solution.

Padas,
I don't see a solution in your posting. I'm already emulating the file structure?

why not use base href + relative path?
