如何获取可见的bing地图的角坐标? [英] How to get coordinates of corners of visible bing map?

问题描述

我正在Windows 8应用程序中使用必应地图"，并且需要在多个位置显示图钉.

I'm using Bing Maps in a windows 8 app and I need to display pushpins at numerous locations.

有什么方法可以获取可见地图拐角处的GPS坐标吗?

Is there any way to get the GPS coordinates of the corners of the visible map?

或者是一种获取可见地图距离的方法? (例如40公里宽，60公里高)

Or alternatively a way to get the distance of the visible map? (e.g. 40km width, 60km height)

我需要这样做，以便将贴在地图上的图钉的数量限制为仅在地图的可见部分上.

I need this in order to limit the number of pushpins I attach to the map to just being the ones on the visible part of the map.

推荐答案

您可以直接从地图实例的 Bounds 属性中获取此信息，该属性返回由Northwest和Southeast lat定义的LocationRect/lng位置显示在当前视图中. http://msdn.microsoft.com/en-us/library/hh846504.aspx
