Verify path

Accepted answer

            string path=@"C:\Desktop";

            if (System.IO.Directory.Exists(path) || System.IO.File.Exists(path))

            {
                MessageBox.Show("true");

            }
            else
            {
                MessageBox.Show("false");
            }

you can check both directory or file exists or not ?
because path man be for directory or file

Well your code is good for testing a "path-string" is correct or not.
But it can't tell a path is valid or not.

if i wrote C:\abc\xy.txt then your code tell the path is correct
but in real there is no that type of path in my com.

So i want to verify path is valid or not...

Thanks for your contribution & well code, :-)
but my problem is not solve yet...

Thank you!

here sample code using regular expressions that will validate an absolute file path on a Windows PC in most cases

using System;
using System.Text.RegularExpressions;

/// 
/// Gets whether the specified path is a valid absolute file path.
/// 

/// Any path. OK if null or empty.
static public bool IsValidPath( string path )
{
    Regex r = new Regex( @"^(([a-zA-Z]\:)|(\\))(\\{1}|((\\{1})[^\\]([^/:*?<>""|]*))+)$" );
    return r.IsMatch( path );
}
