示例

以下示例打印从 GeoCoordinate获取的纬度和经度值。

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();
        }
    }
}

Imports System.Device.Location

Module GetLocationEvent
    Public Class CLocation
        Private WithEvents watcher As GeoCoordinateWatcher
        Public Sub GetLocationDataEvent()
            watcher = New System.Device.Location.GeoCoordinateWatcher()
            AddHandler watcher.PositionChanged, AddressOf watcher_PositionChanged
            watcher.Start()

        End Sub

        Private Sub watcher_PositionChanged(ByVal sender As Object, ByVal e As GeoPositionChangedEventArgs(Of GeoCoordinate))
            PrintPosition(e.Position.Location.Latitude, e.Position.Location.Longitude)
            ' Uncomment the following to stop receiving updates after the first one.
            ' watcher.Stop()
        End Sub

        Private Sub PrintPosition(ByVal Latitude As Double, ByVal Longitude As Double)
            Console.WriteLine("Latitude: {0}, Longitude {1}", Latitude, Longitude)
        End Sub
    End Class


    Public Sub Main()
        Dim myLocation As New CLocation()
        myLocation.GetLocationDataEvent()
        Console.WriteLine("Enter any key to quit.")
        Console.ReadLine()
    End Sub

注解

维度的范围为 -90.0 到 90.0。 纬度以赤道以北或南度为单位。 正值位于赤道以北，负值位于赤道以南。
