XP上的WPF列表框崩溃

为什么此列表框在windows XP上崩溃，而不是在Vista或windows 7上崩溃

它构建得很好，没有错误，但是当我试图在xp中运行它时，崩溃了，我得到了这个错误。。 System.FormatExection

我在您的XAML中看到的唯一可能受操作系统版本影响的东西是

Font=“Calibri”

，因为XP将安装不同于Vista/Win7的字体，并且WPF有自己的字体处理。也许就是这样，但可能不是

我建议您发布一个FormatException的堆栈跟踪。这可能会提供一些真正的线索。同时，尝试将XAML缩减到给出错误所需的最小值。那么我们就更有可能看到它。

这是字体。谢谢你的帮助
