如何将Shapefile添加到地图？

Question

ShapeFile类的名称空间是什么？

我的语言在Esri Map中是银色的：

                            

                        <esri:GraphicsLayer ShowLegend="false" ID="ResultsGraphicsLayer" />
                        <esri:GraphicsLayer ShowLegend="false" ID="MyGraphicsLayer" />
                        <esri:GraphicsLayer ShowLegend="false" ID="MySelectionGraphicsLayer" MouseEnter="GraphicsLayer_MouseEnter" MouseLeave="GraphicsLayer_MouseLeave"/>
                        <esri:GraphicsLayer ShowLegend="false" ID="IdentifyIconGraphicsLayer"/>

                    </esri:Map>

private void openFileDialog_Click（object sender，RoutedEventArgs e）         {             //创建对话框，允许用户选择＆＃34; .shp＆＃34;和＆＃34; .dbf＆＃34;档             OpenFileDialog ofd = new OpenFileDialog（）;             ofd.Multiselect = true;

        if( !( ofd.ShowDialog() ?? false ) )
            return;

        //Get the file info objects for the SHP and the DBF file selected by the user
        FileInfo shapeFile = null;
        FileInfo dbfFile = null;
        foreach( FileInfo fi in ofd.Files )
        {
            if( fi.Extension.ToLower() == ".shp" )
            {
                shapeFile = fi;
            }

            {
                dbfFile = fi;
            }
        }

        //Read the SHP and DBF files into the ShapeFileReader
        ShapeFile shapeFileReader = new ShapeFile();
        if( shapeFile != null && dbfFile != null )
        {
            shapeFileReader.Read( shapeFile, dbfFile );
        }
        else
        {
            HtmlPage.Window.Alert( "Please select a SP and a DBF file to proceed." );
            return;
        }

        //Add the shapes from the shapefile into a graphics layer named "shapefileGraphicsLayer"
        //the greaphics layer should be present in the XAML or created earlier
        GraphicsLayer graphicsLayer = MyMap.Layers[ "shapefileGraphicsLayer" ] as GraphicsLayer;
        foreach( ShapeFileRecord record in shapeFileReader.Records )
        {
            Graphic graphic = record.ToGraphic();
            if( graphic != null )
                graphicsLayer.Graphics.Add( graphic );
        }
