C#中的Concat数据绑定和静态文本

所以我有一个带有数据绑定的文本框,但我想在我的xaml代码中添加静态文本.

<TextBlock Text="{Binding Preptime}"></TextBlock>

这只会显示分钟数,我希望它显示为:"准备时间:55分钟"

        public String Preparation
    {
        get { return "Preparation time: " + Preptime + " minutes"; }
    }

我知道我可以使用一个getter来做一个干净的解决方案,但必须有一种方法将它直接写入我的xaml？

提前致谢!
