FontFamily获取中文名字

这毛问题困扰我几天了，主要是关键字不好搜索，不过进过大量的点击搜索，无意中打开一个网页，居然找到了

设置字体，我们都喜欢这样

<Grid>
                    <Grid.Resources>
                        <CollectionViewSource x:Key="sysFonts" Source="{x:Static Member=Fonts.SystemFontFamilies}"></CollectionViewSource>
                    </Grid.Resources>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="1*"></ColumnDefinition>
                        <ColumnDefinition Width="3*"></ColumnDefinition>
                    </Grid.ColumnDefinitions>
                    <Label Content="选择字体:" Grid.Column="0"></Label>
                    <ComboBox Grid.Column="1" ItemsSource="{Binding Source={StaticResource sysFonts}}" SelectedValue="{Binding FontFamilySelected}"></ComboBox>
                </Grid>

但是，有个问题，这样做ComboBox中是这样的

全是英文的，什么宋体呀，都是英文的，这样不好，那么要怎么样做呢，请看原文地址http://www.oschina.net/code/snippet_67021_837

我做的话，那就在后台做，做一个类型转换器Converet

public class StringToFontFamily : IValueConverter
    {

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            FontFamily fontfamily = (FontFamily)value;
            LanguageSpecificStringDictionary lsd = fontfamily.FamilyNames;
            if (lsd.ContainsKey(XmlLanguage.GetLanguage("zh-cn")))
            {
                string fontname = null;
                if (lsd.TryGetValue(XmlLanguage.GetLanguage("zh-cn"), out fontname))
                {
                    return fontname;
                }
            }
            else
            {
                string fontname = null;
                if (lsd.TryGetValue(XmlLanguage.GetLanguage("en-us"), out fontname))
                {
                    return fontname;
                }
            }
            return "Arial";
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            string fontname = (string)value;
            FontFamily fontfamily = new FontFamily(fontname);
            return fontfamily;
        }
    }

private void InitFontFamily()
        {
            foreach (FontFamily fontfamily in Fonts.SystemFontFamilies)
            {
                LanguageSpecificStringDictionary lsd = fontfamily.FamilyNames;
                if (lsd.ContainsKey(XmlLanguage.GetLanguage("zh-cn")))
                {
                    string fontname = null;
                    if (lsd.TryGetValue(XmlLanguage.GetLanguage("zh-cn"), out fontname))
                    {
                        cboFontFamily.Items.Add(fontname);
                    }
                }
                else
                {
                    string fontname = null;
                    if (lsd.TryGetValue(XmlLanguage.GetLanguage("en-us"), out fontname))
                    {
                        cboFontFamily.Items.Add(fontname);
                    }
                }
            }
        }

我们看到中文了。。。
