Bing Maps控件【WP7学习札记之十七】

      本节是WP7学习札记的第十六篇了，接近学习的尾声，本节主要讲Bing Maps控件的一般使用，不讲如何注册Bing Maps 账户，申请Bing Maps 使用key，内容页不包含使用Bing Maps SOAP服务计算路径~相关内容请参考MSDN的文档，地址为：http://msdn.microsoft.com/zh-cn/library/ff941096(v=vs.92).aspx

      内容主要为：地图的缩放、地图模式的设置、定位、Pushpin等，废话不多说，附上代码:

MainPage.xaml的xaml代码如下：

MainPage.xaml.cs代码如下：

using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
//

using System.Device.Location;

namespace BingMaps
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void btnZoomOut_Click(object sender, RoutedEventArgs e)
        {
            double zoom;
            zoom = map1.ZoomLevel;
            map1.ZoomLevel = ++zoom;
        }

        private void btnZoomIn_Click(object sender, RoutedEventArgs e)
        {
            double zoom;
            zoom = map1.ZoomLevel;
            map1.ZoomLevel = --zoom;
        }

        private void btnRoad_Click(object sender, RoutedEventArgs e)
        {
            map1.Mode = new RoadMode();
        }

        private void btnAerial_Click(object sender, RoutedEventArgs e)
        {
            map1.Mode = new AerialMode();
        }

        private void btnCenter_Click(object sender, RoutedEventArgs e)
        {
            map1.SetView(new GeoCoordinate(38.90, -77.04), 15);
        }

        private void btnPushpin_Click(object sender, RoutedEventArgs e)
        {
            MapLayer mapLayer = new MapLayer();
            map1.Children.Add(mapLayer);
            Pushpin pushpin = new Pushpin() { 
              Location= new GeoCoordinate(38.8976,-77.0365),
             Content="白宫"
            };
            mapLayer.AddChild (pushpin, pushpin.Location);
        }
    }
}

程序运行效果如下：
