大佬教程收集整理的这篇文章主要介绍了GIS silverlight随堂作业2街景图卫星图切换,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
在作业1基础上
1.添加引用,加载图层,输网址的地方再粘一遍链接,1个是街景图,一个是卫星图,并分别加一个ID,如下
<esri:ArcGISTiledMapserviceLayer Url="http://services.arcgisonline.com/arcgis/rest/services/ESRi_iR_488_11845@agery_World_2D/MapServer" ID="imamap" /> <esri:ArcGISTiledMapserviceLayer Url="http://services.arcgisonline.com/arcgis/rest/services/ESRI_StreetMap_World_2D/MapServer" ID="streetmap" />2.拖入2个Button按钮,重命名,双击进入编辑页面,设置2个图层的可见性如下,依次可见不可见,如下。
private void button1_Click(object sender,RoutedEventArgs E) { map1.Layers["streetmap"].Visible = true; map1.Layers["imamap"].Visible = false; } private void button2_Click(object sender,RoutedEventArgs E) { map1.Layers["streetmap"].Visible = false; map1.Layers["imamap"].Visible = true; }3.要求打开后在中国,设置Extent,在代码行里
<esri:Map BACkground="White" HorizontalAlignment="Left" <strong><span style="color:#3333ff;">Extent="60,60,130,13"</span></strong> Name="map1" VerticalAlignment="Top" WrapAround="True" Height="300" Width="388">
</pre><pre code_snippet_id="623612" snippet_file_name="blog_20150319_4_9858641" name="code" class="csharp">4.点击运行
<UserControl x:Class="ArcGisSilverlight.MainPage" xmlns="http://scheR_488_11845@as.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://scheR_488_11845@as.microsoft.com/winfx/2006/xaml" xmlns:d="http://scheR_488_11845@as.microsoft.com/expression/blend/2008" xmlns:mc="http://scheR_488_11845@as.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:esri="clr-namespace:ESRI.ArcGIs.CLIENt;assembly=ESRI.ArcGIs.CLIENt" xmlns:esriGeometry="clr-namespace:ESRI.ArcGIs.CLIENt.Geometry;assembly=ESRI.ArcGIs.CLIENt" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" BACkground="White"> <esri:Map BACkground="White" HorizontalAlignment="Left" Extent="60,13" Name="map1" VerticalAlignment="Top" WrapAround="True" Height="300" Width="388"> <esri:Map.Layers> <esri:LayerCollection> <esri:ArcGISTiledMapserviceLayer Url="http://services.arcgisonline.com/arcgis/rest/services/ESRi_iR_488_11845@agery_World_2D/MapServer" ID="imamap" /> <esri:ArcGISTiledMapserviceLayer Url="http://services.arcgisonline.com/arcgis/rest/services/ESRI_StreetMap_World_2D/MapServer" ID="streetmap" /> </esri:LayerCollection> </esri:Map.Layers> </esri:Map> <Button Content="街景图" Height="23" HorizontalAlignment="Left" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> <Button Content="影像图" Height="23" HorizontalAlignment="Left" Margin="81,0" Name="button2" VerticalAlignment="Top" Width="75" Click="button2_Click" /> </Grid> </UserControl>
</pre><p>MainPage.xaml.cs代码</p><p></p><pre code_snippet_id="623612" snippet_file_name="blog_20150319_6_2262910" name="code" class="csharp">using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; namespace ArcGisSilverlight { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); } private void button1_Click(object sender,RoutedEventArgs E) { map1.Layers["streetmap"].Visible = false; map1.Layers["imamap"].Visible = true; } } }
效果如下:
分别按下街景图,影像图可以自由切换。
