我遇到了同样的问题，即多个图钉靠在一起，并且当我单击图钉时有其他内容可以显示时，该问题更加严重.

I had the same problem where I had multiple pushpins close together and the problem was exacerbated when I had additional content to show when the pushpin was clicked.

我解决此问题的方法是删除图钉，然后重新添加它.这样，它就成为了最高的图钉.

The way I got around this problem was to remove the pushpin and then re-add it. That way it became the topmost pushpin.

map1.Children.Remove(pushpin);
map1.Children.Add(pushpin);
