小功能一:要求在鼠标在地图上滑动时,显示出鼠标在地图上所处位置的经纬度坐标.

我们先在Bing Map控件的元素<Map>　里面添加一个鼠标滑动的事件 .如上代码中,定的事件MouseMove="mapone_MouseMove" 注意:我这里给<Map>元素定了个Name,后面要用到的　Name="mapone"

事件定好了,我们还要在界面上给一个或两个控件用于显示经纬坐标信息.　我这里是在后台代码中动态添加的几个Label控件.大伙可以自己去工具箱里面拖出来放到界面上.

那现在我们来看看后台代码:

        /// <sumMary>
        /// 鼠标移动事件
        /// </sumMary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void mapone_MouseMove(object sender,MouseEventArgs E)
        {
            //获取动态添加的两个Label控件
            Label latValue = this.mapOperationPanel.FindName("latX") as Label;
            Label longValue = this.mapOperationPanel.FindName("longY") as Label;


            //根据鼠标在控件(地图控件maponE)的布局位置来获取鼠标在地图中的位置
            LOCATIOn mapLOCATIOn = this.mapone.ViewportPointToLOCATIOn(e.GetPosition(this.maponE));


            //把得到的经纬度坐标信息显示出来.
            latValue.Content = mapLOCATIOn.Latitude.ToString();
            longValue.Content = mapLOCATIOn.Longitude.ToString();
        }
