aspx_beginners thread: File.Exists? FileInfo.Exists?

I want to ensure that a file exists before I access the file.
I have tried
File.Exists
and
FileInfo.Exists
But for some reason the file is coming up as not existing, when it does
exist.
Can someone tell me why this is happening?
Am I using the right test to ensure that the file exists.

If the file is in a 'virtual' directory(ie part of your web site) you might
need to get it's actual full path name by using a call such as
strFullPath = Current.Server.MapPath( strRelativeFileName )
Hope it helps.

Please submit the code you're testing with.

Hi
Here is the code I have for testing the file.
The file is in the current directory which is not a virtual directory.
The application runs without error when I don't test for file existing.
private string xmlLocation = "News.xml";
FileInfo theFile = new FileInfo(xmlLocation);
if ( theFile.Exists )
{
myDataSet.ReadXml(Server.MapPath(xmlLocation));
return myDataSet;
}
else
{
throw new FileNotFoundException("File not found: ", xmlLocation);
}

Hi
Here is the code that I'm using.
The file is not in a virtual directory.
string path = @"\News\";
string fullPath = "";
fullPath = (Path.GetFullPath(path));
FileInfo theFile = new FileInfo(fullPath.ToString());
if ( ! theFile.Exists )
{
throw new FileNotFoundException("File not found: ", xmlLocation);
}

Have you tried replacing the server.mappath with the full physical path
