让WPF的TextBox控件可以使用System.Windows.Forms.FontDialog设置样式

      虽然WPF非常强大，但一时没找到字体设置对话框，就先拿Windows.Forms.FontDialog将就着用吧。WPF的TextBox可以接受的样式比FontDialog能够设置的样式多些，但这里只选用了FontDialog可以设置的项，需要更高级功能的朋友可以参考这个帖子。

 

      实现非常简单，就没写注释。因为Forms与WPF存在相同名称的类型，为了方便，这里使用了全名称空间限定。

 

      另外需要说明的一点是：FontDialog默认是不显示颜色选择区域的，需要将其ShowColor属性设置为true。
