How to check if a Font is already installed

5

I have a C # program that checks whether a font is already installed or not, but it is not working right:

I'm trying with the following code

if (File.Exists(@"C:\Windwos\Fonts\Agency FB"))

Would anyone know how I can verify by the name of the source?
