how to know local font names in silverlight

Question

Hi, in silverlight 4 I need to know all the font names in my machines. Using....

...

 var typefaces = System.Windows.Media.Fonts.SystemTypefaces;

        foreach (System.Windows.Media.Typeface face in typefaces)
        {

            System.Windows.Media.GlyphTypeface a;
            face.TryGetGlyphTypeface(out a);
            FontSource fs = new FontSource(a);

           var b = a.FontFileName;

...

I only can get FontFileName but actually we'd need the fontname for showing it....

How can get such info?

thanks you all!

Answer 1

Generate a lookup table for Silverlight:

WPF has the properties to do this, but Silverlight does not.

If you look at the System.Windows.Media.Typeface objects in the debugger the fonts do not contain anything except 2 version numbers and the FontUri (read filename).

You could generate a lookup dictionary by running code under WPF to extract all the filenames and matching fontnames, but you need to do that on a machine with every font installed that you want to cover.

The WPF code below extracts such a table (this one contains the font names in all languages, so you will probably want to add a filter to it e.g. by "en-us"):

    foreach (var font in System.Windows.Media.Fonts.SystemTypefaces)
    {
        System.Windows.Media.GlyphTypeface glyphTypeface;
        font.TryGetGlyphTypeface(out glyphTypeface);
        var dictionary = font.FaceNames;
        foreach (var language in dictionary.Keys)
        {
            Debug.WriteLine(string.Format("\"{0}\", \"{1}\", \"{2}\"", glyphTypeface.FontUri.Segments[glyphTypeface.FontUri.Segments.Count()-1], language, dictionary[language]));
        }
    }

Part of the output is shown below and could be easily formatted into a table or loaded as a dictionary in Silverlight:

Hi, But the font.FaceNames don't allow at SilvetLight.
