Question

我开始使用Silverlight Bing Maps控件。如何使用C＃以编程方式将图钉添加到地图中？

谢谢！

未知，

以下是构建Silverlight应用程序的分步说明，该应用程序显示美国的Bing地图，并在每个单击的位置添加图钉。只是为了好玩，我在浏览图钉时添加了一些“悬停”功能。

第1步：使用Visual Studio（文件/新项目/ Silverlight应用程序）创建示例Silverlight应用程序

第2步：将两个Bing DLL引用添加到Silverlight应用程序项目

Folder: C:\Program Files\Bing Maps Silverlight Control\V1\Libraries\
File 1: Microsoft.Maps.MapControl.dll
File 2: Microsoft.Maps.MapControl.Common.dll

第3步：编辑MainPage.xaml，并在顶部添加以下命名空间：

xmlns:Maps="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"

第4步：编辑MainPage.xaml，并将以下代码放在UserControl的网格中：

<Maps:Map x:Name="x_Map" Center="39.36830,-95.27340" ZoomLevel="4" />

第5步：编辑MainPage.cs，并添加以下using语句：

using Microsoft.Maps.MapControl;

第6步：编辑MainPage.cs，并使用以下代码替换MainPage类：

public partial class MainPage : UserControl
{
    private MapLayer m_PushpinLayer;

    public MainPage()
    {
        InitializeComponent();
        base.Loaded += OnLoaded;
    }

    private void OnLoaded(object sender, RoutedEventArgs e)
    {
        base.Loaded -= OnLoaded;

    m_PushpinLayer = new MapLayer();
    x_Map.Children.Add(m_PushpinLayer);
        x_Map.MouseClick += OnMouseClick;
    }

    private void AddPushpin(double latitude, double longitude)
    {
        Pushpin pushpin = new Pushpin();
        pushpin.MouseEnter += OnMouseEnter;
        pushpin.MouseLeave += OnMouseLeave;
        m_PushpinLayer.AddChild(pushpin, new Location(latitude, longitude), PositionOrigin.BottomCenter);
    }

    private void OnMouseClick(object sender, MapMouseEventArgs e)
    {
        Point clickLocation = e.ViewportPoint;
        Location location = x_Map.ViewportPointToLocation(clickLocation);
        AddPushpin(location.Latitude, location.Longitude);
    }

    private void OnMouseLeave(object sender, MouseEventArgs e)
    {
        Pushpin pushpin = sender as Pushpin;

        // remove the pushpin transform when mouse leaves
        pushpin.RenderTransform = null;
    }

    private void OnMouseEnter(object sender, MouseEventArgs e)
    {
        Pushpin pushpin = sender as Pushpin;

        // scaling will shrink (less than 1) or enlarge (greater than 1) source element
        ScaleTransform st = new ScaleTransform();
        st.ScaleX = 1.4;
        st.ScaleY = 1.4;

        // set center of scaling to center of pushpin
        st.CenterX = (pushpin as FrameworkElement).Height / 2;
        st.CenterY = (pushpin as FrameworkElement).Height / 2;

        pushpin.RenderTransform = st;
    }
}

第7步：构建并运行！
