如何确定已安装字体的O / S文件名？

Question

We use a third-party PDF Generator library which requires that you specify the TrueType or Type1 file name when using a font other than the 14 or so that are part of the default PDF standard.

So if I want to use Bitstream Arrus Bold I have to know to reference arrusb.ttf .

Short of enumerating all of the files in the font folder and creating a disposable PrivateFontCollection to extract the relationships, is there a way to obtain the underlying font name from font information, ie given Courier New, Bold, Italic derive CourBI.ttf ?

I've already looked at the InstalledFontCollection and there's nothing.

If you don't mind poking around in the registry, take a look at

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Fonts

It has pairs like

Name = "Arial (TrueType)"
Data = "arial.ttf"

You can do this the necessary queries like this:

static RegistryKey fontsKey =
    Registry.LocalMachine.OpenSubKey(
        @"Software\Microsoft\Windows NT\CurrentVersion\Fonts");

static public string GetFontFile(string fontName)
{
    return fontsKey.GetValue(fontName, string.Empty) as string;
}

A call to GetFontFile("Arial (TrueType)") returns "arial.ttf"

You could of course modify the code to append the (TrueType) portion to the fontName , or to look through everything returned by fontsKey.GetValueNames() to find the best match.
