ArcGIS api fo silverlight学习二（silverlight加载GraphicsLayer）

上一节学习了silverlight加载GeoServer发布的WMS地图，这一节学习一下加载GraphicsLayer

一、在MainPage.xaml中添加资源配置

<Grid.Resources>
            <esri:SimpleMarkerSymbol x:Key="RedMarkerSymbol" Color="Red" Size="12" Style="Circle" />
            <esri:SimpleMarkerSymbol x:Key="BlackMarkerSymbol" Color="Black" Size="14" Style="Diamond" />
            <esri:PictureMarkerSymbol x:Key="GlobePictureSymbol" OffsetX="8" OffsetY="8"
                Source="images/ttt.png" />
            <esri:SimpleLineSymbol x:Key="DefaultLineSymbol" Color="Green" Style="DashDot" Width="4" />
            <esri:SimpleFillSymbol x:Key="DefaultFillSymbol" Fill="Green" BorderBrush="Blue"
                BorderThickness="3" />
        </Grid.Resources>

二、在cs文件中添加实现函数（以添加图片图标为例，添加其它请参考api官网）

private static ESRI.ArcGIS.Client.Projection.WebMercator mercator =
            new ESRI.ArcGIS.Client.Projection.WebMercator();

private void AddPictureMarkerAndTextGraphics()
        {

　　　　GraphicsLayer g = new ESRI.ArcGIS.Client.GraphicsLayer();
            for (int i = 0; i < 2; i++)
           
                Graphic graphic = new Graphic()
                {
                    Geometry = mercator.FromGeographic(new MapPoint(107.2 + i, 38.1 + i)),
                    Symbol = LayoutRoot.Resources["GlobePictureSymbol"] as Symbol
                };

g.Graphics.Add(graphic);
                
            }
            this.myMap.Layers.Add(g);
        }

添加System.Runtime.Serialization引用

三、调用AddPictureMarkerAndTextGraphics()
