Contoh

Contoh berikut mencetak nilai lintang dan bujur yang diperoleh dari GeoCoordinate.

using System;
using System.Device.Location;

namespace LocationEvent1
{
    class Program
    {
        static void Main(string[] args)
        {
            GeoCoordinateWatcher watcher;
            watcher = new GeoCoordinateWatcher();

            watcher.PositionChanged += (sender, e) =>
            {
                var coordinate = e.Position.Location;
                Console.WriteLine("Lat: {0}, Long: {1}", coordinate.Latitude,
                    coordinate.Longitude);
                // Uncomment to get only one event.
                // watcher.Stop();
            };

            // Begin listening for location updates.
            watcher.Start();
        }
    }
}
