File.Exists() path problem

I'm trying to check for the existence of files in a virtual folder called Audio, which resides in the root of my .NET app.

Is it required that I enter the literal path for File.Exists()?  Because this simple test is not finding the file:
if (File.Exists("test.mp3"))

Yet, this DOES find the file:
if (File.Exists("C:\\Inetpub\\OAS2\\OAS2\\MusicTeam\\test.mp3"))

What I want to do is point to the Audio folder on the root of my app. But this did not work:
if (File.Exists(~/Audio/test.mp3))

Hi Xbradders;

From Microsoft documentation [HERE]:
The path parameter is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, use GetCurrentDirectory() method.

use Server.MapPath

read here : http://msdn.microsoft.com/en-us/library/system.web.httpserverutility.mappath.aspx

It should be something like

if (File.Exists(Server.MapPath("~/Audio/test.mp3")))

So it will look into the Audio folder in the root of your application for test.mp3 file.

Hope this helps.

hi,

You can get the application root path with
string APP_PATH = System.Web.HttpContext.Current.Request.ApplicationPath.ToLower();

then applent your path a

APP_PATH += "Audio/test.mp3"

Hope this helps...

Get The base location and add your defined folder name and file name with it

 Dim base As String = AppDomain.CurrentDomain.BaseDirectory

 Dim Filename as string="test.mp3"

   base = base + Filename   ---> (contain entire filename )

or use

To get base Path of running application ---> use "Application.StartupPath "

and then check existence as below

If System.IO.File.Exists(base ) Then
--Your code here
End If

Sorry for the delay in responding - I got sidetracked with putting out fires.

Thanks for the responses, but I don't think these solutions work with virtual paths, which I am trying to access here.  

The Audio folder is a virtual directory that points to a folder on another server that contains the files I'm checking the existence of.  Is there a special way to refer to files in a virtual folder?  This does not find the file:

File.Exists(Audio/ULTIMATE CLASSIX/XCL001 BEETHOVEN VOL 1/FULL LENGTH/XCL001_06 Egmont - Overture.mp3)

BUT, When I past the path into my browser, it does play the audio, so it is there.  Like so"
http://www.mysite.com/Audio/ULTIMATE CLASSIX/XCL001 BEETHOVEN VOL 1/FULL LENGTH/XCL001_06 Egmont - Overture.mp3

Any idea what I'm doing wrong in code?
