推荐答案

您可以使用它们；

You can use these;

1)

添加"System.Device"；参考

Add "System.Device" Reference

2)

C#

using System.Device.Location;

VB.NET

Imports System.Device.Location

3)
将变量声明为GeoCoordinateWatcher

3)
declare a variable as GeoCoordinateWatcher

C#

GeoCoordinateWatcher gwatcher;

VB.NET

Private WithEvents gwatcher As GeoCoordinateWatcher

2)

假设单击按钮后观察者将启动

C#

Assume that the watcher will start when a button is clicked

C#

 private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            if (gwatcher == null)
            {
                gwatcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
                gwatcher.MovementThreshold = 20;
                gwatcher.StatusChanged += new EventHandler<GeoPositionStatusChangedEventArgs>(gwatcher_StatusChanged);
            }
            gwatcher.Start();
        }

VB.NET

   Private Sub Button_Click_1(sender As Object, e As RoutedEventArgs)
        If gwatcher Is Nothing Then
            gwatcher = New GeoCoordinateWatcher(GeoPositionAccuracy.High)
            gwatcher.MovementThreshold = 20
        End If
        gwatcher.Start()

    End Sub

3)

此处的观察者状态已更改； (假设我们有2个文本块，名称分别为"latitude_txt"和"longitude_txt"，并且当状态更改时，我们将在其上打印输出.

And the watcher status changed here; (Assume that we have 2 textblock that names are "latitude_txt" and "longitude_txt" and when status is changed, we will print the output on these.

C#

void gwatcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
        {
            if (e.Status == GeoPositionStatus.Ready)
            {
                GeoCoordinate co = gwatcher.Position.Location;
                latitude_txt.Text = co.Latitude.ToString("0.000");
                longitude_txt.Text = co.Longitude.ToString("0.000");
                gwatcher.Stop();
            }
        }

VB.NET

    Private Sub gwatcher_StatusChanged(sender As Object, e As GeoPositionStatusChangedEventArgs) Handles gwatcher.StatusChanged
        If e.Status = GeoPositionStatus.Ready Then
            Dim co As GeoCoordinate = gwatcher.Position.Location
            latitude_txt.Text = co.Latitude.ToString("0.000")
            longitude_txt.Text = co.Longitude.ToString("0.000")
            gwatcher.Stop()
        End If
    End Sub
