Test if a Font is installed

let say Im using an installed font on the system:

new System.Drawing.Font("Arial", 120F);

everything is fine. Now if I would use a not existing font:

new System.Drawing.Font("IdoNotExistHaHa", 120F);

I dont get any exception. As I see, if I use a font that doesnt exist I get a standard font (arial?, not sure). Whatever, I would like to throw an exception if there is a not found font. How to?

Answer 1

MSDN says as following :

For more information about how to construct fonts, see How to:
Construct Font Families and Fonts. Windows Forms applications support
TrueType fonts and have limited support for OpenType fonts. If you
attempt to use a font that is not supported, or the font is not
installed on the machine that is running the application, the
Microsoft Sans Serif font will be substituted.

You can check the if the font is correct by doing as following :

var myFont = new Font(fontName)
if (myFont.Name != fontName ) 
{ 
    throw new Exception()
}
