Question

您好我正试图让我的Bing地图api读取一个文本框，该文本框中会有一个邮政编码或地址，它会找到。目前经过大量的反复试验，我已经通过坐标坐标进行搜索，坐标坐标直接输入到Xaml按钮内的标签选项中。我想知道是否有人知道如何添加文本框，用户可以简单地输入地址。

文本框（地址） - ＆gt;按钮（点击）----＆gt;地图搜索

当前Xaml代码

        <Button Content="Button" HorizontalAlignment="Left" Height="30" VerticalAlignment="Top" Width="99" Margin="92,279,0,0" Click="ChangeMapView_Click" x:Name="BTN1" Tag="39.3683,-95.2734,0.0000 4.0000"/>
        <TextBox HorizontalAlignment="Left" Height="32" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="111" Margin="212,277,0,0" x:Name="TXT1"/>
    </m:Map>
</Grid>
</Window>

VB代码

   Private Sub ChangeMapView_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ' Parse the information of the button's Tag property
    Dim tagInfo() As String = (CType(sender, Button)).Tag.ToString().Split(" "c)
    Dim center As Location = CType(locConverter.ConvertFrom(tagInfo(0)), Location)
    Dim zoom As Double = System.Convert.ToDouble(tagInfo(1))


    ' Set the map view
    BingMap.SetView(center, zoom)

End Sub

您必须将用户查询传递到Bing Maps REST地理编码服务才能获得它的坐标。您可以在此处找到有关如何执行此操作的文档：https://msdn.microsoft.com/en-us/library/hh757509.aspx
