The reason why your code doesn't work is that GetDirectoryName returns no \ at the end. That's even documented:

The string returned by this method consists of all characters in the path up to but not including the last DirectorySeparatorChar or AltDirectorySeparatorChar

Use Path.Combine to get the correct directory separator char:

string path =  Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "tres.xml");
if(File.Exists(path))
{
    // ...
}

You can just simply use:

File.Exists("tres.xml");

This checks the current directory of your .exe

Note that it is the _current directory of your .exe_, that means `bin\Debug` (if you run from VS) and not your project root. – BrunoLM Dec 09 '16 at 10:12
