C# 获取系统所有字体

获取已安装的所有字体列表

System.Drawing.FontFamily

     StringBuilder str = new StringBuilder();
     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();
     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。
