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

Other answers proposed using Font creation only work if the FontStyle.Regular is available. Some fonts, for example Verlag Bold, do not have a regular style. Creation would fail with exception Font 'Verlag Bold' does not support style 'Regular'. You'll need to check for styles that your application will require. A solution follows:

  public static bool IsFontInstalled(string fontName)
  {
     bool installed = IsFontInstalled(fontName, FontStyle.Regular);
     if (!installed) { installed = IsFontInstalled(fontName, FontStyle.Bold); }
     if (!installed) { installed = IsFontInstalled(fontName, FontStyle.Italic); }

     return installed;
  }

  public static bool IsFontInstalled(string fontName, FontStyle style)
  {
     bool installed = false;
     const float emSize = 8.0f;

     try
     {
        using (var testFont = new Font(fontName, emSize, style))
        {
           installed = (0 == string.Compare(fontName, testFont.Name, StringComparison.InvariantCultureIgnoreCase));
        }
     }
     catch
     {
     }

     return installed;
  }
