如何确定已安装字体的O/S文件名?

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

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

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;
}

致电 GetFontFile("Arial (TrueType)") 回报 "arial.ttf"

当然,您可以修改代码以附加 (TrueType) 部分到 fontName fontsKey.GetValueNames() 找到最好的匹配。
