File.Exists and Virtual path

Question

Sorry for the dumb question, but I'm trying to use File.Exists to check if a file exists in a Virtual Folder '~/XML/Test.xml/', but no matter what ever I try the file isn't detected. I've tested the basic C# code to test the file in @"C:	est.xml" and this works fine. Is there a better solution other than File.Exists that might work?
Example Code:
using System.IO;
string path = "~/XML/Test.xml" ;
if ( File .Exists(path))
{
textBox1.Text = "File does exist" ;
}
else
{
textBox1.Text = "File does not exist" ;
}

I hope your application is Web. Try following
Copy the filder "XML" to root directory
Then use the Server.MapPath() like below
using System.IO;
string path = Server.MapPath(@ "XML\Test.xml")
if ( File .Exists(path))
{
textBox1.Text = "File does exist" ;
}
else
{
textBox1.Text = "File does not exist" ;
}
