Question

i want to set a link in VB.net dynamically to a file.
My url looks like that:

http://server/folder/folder2/file.aspx?get=param

I tried to use Request.URL but i have not found any solution to get only

http://server/folder/folder2/

without the query string and without the filename.

Please help.

You can easily get a relative file path using the Request instance, then work with that, using Path class ought to help:

Dim relativePath = Request.AppRelativeCurrentExecutionFilePath
Dim relativeDirectoryPath = System.IO.Path.GetDirectoryName(relativePath)

It’s worth noting that GetDirectoryName might transform your slashes, so you could expand the path:

Dim mappedPath = HttpContext.Current.Server.MapPath(newpath)

So, to remove redundancy, we could shorten this:

Dim path = _ 
    Server.MapPath( _ 
        Path.GetDirectoryName( _ 
            Request.AppRelativeCurrentExecutionFilePath)))

But you’ll need to check for possible exceptions.
