How to get city coordinates?

Question

Hi,
Is there any way to get city coordinates, such as latitude and longitude based on user's input?
I have TextBox element and when user enters, for example, New York app should get latitude and longitude for that city.

Hi Matthew_42,

Yes, it is possible. We can use the
GeocodeQuery Class to help us.
For more information, please try to refer to my example:
In the MainPage.xaml:
<Button Content="GetCoordinate" Click="Button_Click" Margin="252,32,0,503"></Button>
<TextBox Name="MyTextBox" HorizontalAlignment="Left" Height="72" Margin="0,32,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="267"/>
<TextBlock Name="MyTextBlock" Foreground="Red" FontSize="25" HorizontalAlignment="Left" Margin="10,179,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Height="80" Width="436"/>
<TextBlock Name="MyTextBlock1" Foreground="Red" FontSize="25" HorizontalAlignment="Left" Margin="10,221,0,-9" TextWrapping="Wrap" VerticalAlignment="Top" Height="80" Width="436"/>
In the MainPage.xaml.cs:
private async void Button_Click(object sender, RoutedEventArgs e)
// Get my position
var MyPosition = await new Geolocator().GetGeopositionAsync();
double MyPositionLatitude = MyPosition.Coordinate.Latitude;
double MyPositionLongitude = MyPosition.Coordinate.Longitude;
//Get the search city's Coordinate
var MyGeocodeQuery = new GeocodeQuery();
MyGeocodeQuery.SearchTerm = MyTextBox.Text;
MyGeocodeQuery.GeoCoordinate = new GeoCoordinate(MyPositionLatitude,MyPositionLongitude);
MyGeocodeQuery.QueryCompleted += MyGeocodeQuery_QueryCompleted;
MyGeocodeQuery.QueryAsync();
public void MyGeocodeQuery_QueryCompleted(object sender, QueryCompletedEventArgs<IList<MapLocation>> e)
if(e.Result.Count>0)
int count = e.Result.Count;
double Latitude= e.Result[0].GeoCoordinate.Latitude;
double Longitude = e.Result[0].GeoCoordinate.Longitude;
MyTextBlock.Text = MyTextBox.Text + "_Latitude=" + Latitude.ToString();
MyTextBlock1.Text = MyTextBox.Text + "_Longitude=" + Longitude.ToString();
The result:
