必應地圖-未處理WebException

Question

我正在嘗試在我的項目中實施bing地圖。 我只是將地圖拖放到“地圖”頁面中。

現在，我只是從主頁導航到“地圖”頁面。 加載地圖時，出現異常

WebException was unhandled 

錯誤消息是：

System.Net.WebException was unhandled

我沒有執行任何其他功能。 只需導航到一頁到另一頁即可。 請讓我知道為什么會發生此錯誤？

提前致謝..

Answer 1

關鍵是問題。 現在只有我意識到Bing Map Key對於實時項目非常重要。 現在我解決了我的問題。

<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>

現在工作正常。

感謝所有支持我找到問題的人。 謝謝。
