Are you looking for something like this?:
你在寻找这样的东西吗？：
<TextBox Text="{Binding Path=Txt, StringFormat=C}"/>
回答by eMko
You can use something like this
你可以使用这样的东西
<TextBox TextAlignment="Right"
Text="{Binding Price,
UpdateSourceTrigger=PropertyChanged,
StringFormat='#.00',
ConverterCulture={x:Static sysglb:CultureInfo.CurrentCulture}}"/>
which forces the text to have right alignment and to have a format like 105.00 or 19.95 with decimal point/comma depending on user system settings. You can also add a currency sign to string format if applicable.
这会强制文本正确对齐，并根据用户系统设置使用 105.00 或 19.95 等格式，带小数点/逗号。如果适用，您还可以向字符串格式添加货币符号。
Edit: Sorry, I am spoiled with automatic importing of namespaces. In your top-level element (Usercontrol, Window, ...) add:
编辑：对不起，我被命名空间的自动导入宠坏了。在您的顶级元素（用户控件、窗口等）中添加：
<UserControl x:Class="..."
...
xmlns:sysglb="clr-namespace:System.Globalization;assembly=mscorlib"
...
>
