介面上新增控制元件

<usercontrol:MapControl
    x:Name="mapControl"
    Panel.ZIndex="100"
    MaxZoom="24"
    MinZoom="1"
    Zoom="13" />

在介面的Loaded中新增

  mapControl.CacheLocation = Environment.CurrentDirectory + "\\GMapCache\\"; //快取位置
  //mapControl.MapProvider = GMapProviders.GoogleChinaMap; // 這裡需要填寫地圖提供商，官方預設包含Google地圖
  //mapControl.MapProvider = GaoDeimgProvider.Instance; // 這裡需要填寫地圖提供商，官方預設包含Google地圖
  mapControl.MapProvider = AMapProvider.Instance; // 這裡需要填寫地圖提供商，官方預設包含Google地圖
  mapControl.MinZoom = 2;  //最小縮放
  mapControl.MaxZoom = 17; //最大縮放
  mapControl.Zoom = 5;     //當前縮放 
  mapControl.ShowCenter = true; //不顯示中心十字點
  mapControl.DragButton = MouseButton.Left; //左鍵拖拽地圖
  mapControl.Position = new PointLatLng(32.064, 118.704); //地圖中心位置：珠  海
