Test if a Font is installed

Question

Is there an easy way (in .Net) to test if a Font is installed on the current machine?

Answer 1

How do you get a list of all the installed fonts?

var fontsCollection = new InstalledFontCollection();
foreach (var fontFamiliy in fontsCollection.Families)
{
    if (fontFamiliy.Name == fontName) ... \\ installed
}

See InstalledFontCollection class for details.

MSDN:
Enumerating Installed Fonts

Answer 2

string fontName = "Consolas";
float fontSize = 12;

Font fontTester = new Font( 
    fontName, 
    fontSize, 
    FontStyle.Regular, 
    GraphicsUnit.Pixel );

if ( fontTester.Name == fontName )
{
    // Font exists
}
else
{
    // Font doesn't exist
}

Answer 3

Thanks to Jeff, I have better read the documentation of the Font class:

If the familyName parameter specifies a font that is not installed on the machine running the application or is not supported, Microsoft Sans Serif will be substituted.

The result of this knowledge:

    private bool IsFontInstalled(string fontName) {
        using (var testFont = new Font(fontName, 8)) {
            return 0 == string.Compare(
              fontName,
              testFont.Name,
              StringComparison.InvariantCultureIgnoreCase);
        }
    }

Answer 4

I would prefer the first solution of creating the font and testing that name rather than getting all the installed font names and searching for a particular name.
