Question

我正在尝试在我的项目中实现bing贴图。我只需将地图拖放到地图页面。

现在我只需从主页面导航到Map页面。当加载map时，我得到了

的异常

WebException was unhandled

错误消息是：

System.Net.WebException was unhandled

我没有做任何其他功能。只需导航到一个页面到另一个页面。请让我知道为什么会出现这种错误？

提前致谢..

关键是问题。现在只有我意识到Bing Map Key对于实时项目非常重要。现在我解决了我的问题。

<Grid x:Name="MapPageUIContainer" Grid.Row="1" Margin="2,0,2,0">         
            <my:Map Height="688" HorizontalAlignment="Left" Margin="0,80,0,0" Name="map1" VerticalAlignment="Top" Width="478" CredentialsProvider="My Key"/> 
        </Grid>

现在工作正常。

感谢所有支持我找到问题的人。谢谢。
