如何检查路径集合是否与另一个路径？

Question

我收到了这段代码：

var intersectionDetail = path1.Data.FillContainsWithDetail(path2.Data);    
if (intersectionDetail != IntersectionDetail.NotCalculated &&
    intersectionDetail != IntersectionDetail.Empty)
{
   //collision
}

.FillContainsWithDetail仅适用于wpf，有没有办法在Windows Phone中执行此操作？
