Trying to use Geocoding

Question

Hello everyone.

I am new to the whole bingMaps and have been doing some work with the Geocoding side of things. I get an error that I can't seem to figure out.

This is the error "Cannot implicitly convert the type 'LocatingLocalSuppliers.GeocodingService.GeocodLocation' to 'Microsoft.Maps.MapControl.Location"

Can anyone help me on this.

Here is the code I am using

MainPage.xaml

<UserControl x:Class="LocatingLocalSuppliers.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"    
    xmlns:bing="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid 
        x:Name="LayoutRoot" 
        Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="30"/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <bing:Map
            Grid.RowSpan="2"
            x:Name="myMap" CredentialsProvider="MyKey"/>
    </Grid>
</UserControl>

            GeocodingService.GeocodeServiceClient myGeoCodeClient = new GeocodingService.GeocodeServiceClient("BasicHttpBinding_IGeocodeService");          
            // create an event hanler for GeocodeCompleted event as the service would be call asynchronously
            myGeoCodeClient.GeocodeCompleted += new EventHandler<LocatingLocalSuppliers.GeocodingService.GeocodeCompletedEventArgs>(myGeoCodeClient_GeocodeCompleted);

            myGeoCodeRequest.Query = Address;

            // Pass the request to GeocodeAsyn method
            myGeoCodeClient.GeocodeAsync(myGeoCodeRequest);

        }

        void myGeoCodeClient_GeocodeCompleted(object sender, LocatingLocalSuppliers.GeocodingService.GeocodeCompletedEventArgs e)
        {
            // create a map layer
            MapLayer myMapLayer = new MapLayer();
            myMap.Children.Add(myMapLayer);

            // create a location collection class
            LocationCollection myLocationColl = new LocationCollection();

            foreach (GeocodingService.GeocodeResult gr in e.Result.Results)
            {
                Pushpin myPushPin = new Pushpin();
                // set it to first found location
                myPushPin.Location = gr.Locations[0];
                // add it to location collection
                // which would be used to set the map's bound
                myLocationColl.Add(myPushPin.Location);
                // Add the drawn point to the route layer.                   
                myMapLayer.Children.Add(myPushPin);
            }
            var bounds = new LocationRect(myLocationColl);
            myMap.SetView(bounds);
        }
    }
}

Thanks all

Don't use the Bign MAps SOAP services. They are old and slow. Use the Bing Maps REST services. Information on how to use the REST services in .NET take a look at this blog post: http://rbrundritt.wordpress.com/2012/01/06/bing-maps-rest-service-net-libraries/

In your use case, you are binding the Location returned by your service (from the service reference you added, you got client proxy classes) to the Location inside your control.

The error said that you're not using the right type of location, so basicaly, what you can easily do is to change the line where you're binding the location.

Pushpin myPushPin = new Pushpin();
                // set it to first found location
                myPushPin.Location = new Microsoft.Maps.WPF.Location(gr.Locations[0].Latitude, gr.Locations[0].Longitude);
                // add it to location collection
                // which would be used to set the map's bound
                myLocationColl.Add(myPushPin.Location);
                // Add the drawn point to the route layer.                   
                myMapLayer.Children.Add(myPushPin);

That worked thanks. Can you breifly explain why I need to do that. So I can better understand it so I don't make the same mistake.

Thanks

Answer 4

The two different Location objects are from different Namespaces. The SOAP service is unaware of the Location class that is in WPF control and vice versa. The WPF control may have some internal methods to it that are not available in the Location object from the SOAP service. Thus, only Location objects from the WPF control can be used with the WPF map control.
