如何使用必应地图 WPF 控件

  • 框架使用.NET40
  • Visual Studio 2019;
  • Bing Maps WPF 控件需要 .NET Framework 4.0Windows SDK。这两个组件都随Microsoft Visual Studio VisualC#Visual Basic Express Edition一起安装。
  • 下面演示如何使用。
  • 引用 Microsoft.Maps.MapControl.WPF.dll 也可以在nuget上找到。
  • 添加命名空间。
  • 新建AMapTitleLayer.cs继承图层MapTileLayer实现加载高德地图瓦片.

1)新建 AMapTitleLayer.cs 代码如下:

using Microsoft.Maps.MapControl.WPF;
using System;

namespace WPFDevelopers.Samples.ExampleViews
{
    public class AMapTitleLayer : MapTileLayer
    {
        public AMapTitleLayer()
        {
            TileSource = new AMapTileSource();
        }

        public string UriFormat
        {
            get { return TileSource.UriFormat; }
            set { TileSource.UriFormat = value; }
        }
    }
    public class AMapTileSource : TileSource
    {
        public override Uri GetUri(int x, int y, int zoomLevel)
        {
            string url = string.Format("http://wprd01.is.autonavi.com/appmaptile?x={0}&y={1}&z={2}&lang=zh_cn&size=1&scl=1&style=7", x, y, zoomLevel);
            return new Uri(url, UriKind.Absolute);
        }
    }
}

2)新建PushpinModel.cs 代码如下:

using Microsoft.Maps.MapControl.WPF;

namespace WPFDevelopers.Samples.ExampleViews
{
    public class PushpinModel
    {
        public Location Location { getset; }
        public int ID { getset; }
        public string Title { getset; }
    }
}

3)新建 BingAMapExample.xaml 代码如下:
