    StringBuilder str = new StringBuilder(2000);
    InstalledFontCollection fonts = new InstalledFontCollection();
    foreach (FontFamily family in fonts.Families)
    {
        str.Append(family.Name);
        str.AppendLine();
    }
    ContentTextBlock.Text = str.ToString();

获取区域语言字体列表

System.Windows.Media.FontFamily

    StringBuilder str = new StringBuilder(2000);
    CultureInfo currentCulture = CultureInfo.CurrentUICulture;
    CultureInfo enUsCultureInfo = new CultureInfo("en-US");
    foreach (var family in Fonts.SystemFontFamilies)
    {
        foreach (var keyPair in family.FamilyNames)
        {
            var specificCulture = keyPair.Key.GetSpecificCulture();
            if (specificCulture.Equals(currentCulture) || specificCulture.Equals(enUsCultureInfo))
            {
                if (keyPair.Key != null && !string.IsNullOrEmpty(keyPair.Value))
                {
                    str.Append(keyPair.Value);
                    str.AppendLine();
                }
            }
        }
    }
    ContentTextBlock.Text = str.ToString();

 注：有些电脑因系统缺陷或者系统更新冲突，导致System.Windows.Media.Fonts引用失败。所以建议加个异常捕获处理。
