GeoCoordinateWatcher.StatusChanged 이벤트

정의

네임스페이스:
System.Device.Location
어셈블리:
System.Device.dll

개체의 GeoCoordinateWatcher 상태가 변경되었음을 나타냅니다.

public:
 event EventHandler<System::Device::Location::GeoPositionStatusChangedEventArgs ^> ^ StatusChanged;
public event EventHandler<System.Device.Location.GeoPositionStatusChangedEventArgs> StatusChanged;
member this.StatusChanged : EventHandler<System.Device.Location.GeoPositionStatusChangedEventArgs> 
Public Custom Event StatusChanged As EventHandler(Of GeoPositionStatusChangedEventArgs) 
Public Event StatusChanged As EventHandler(Of GeoPositionStatusChangedEventArgs)

이벤트 유형

EventHandler<GeoPositionStatusChangedEventArgs>

구현

StatusChanged

예제

다음 예제에서는 이벤트를 처리하는 StatusChanged 방법을 보여 줍니다.

using System;
using System.Device.Location;
namespace ShowStatusUpdates
{
    class Program
    {
        static void Main(string[] args)
        {
            ShowStatusUpdates();
        }

        static void ShowStatusUpdates()
        {
            GeoCoordinateWatcher watcher = new GeoCoordinateWatcher();
            watcher.Start();

            watcher.StatusChanged += new EventHandler<GeoPositionStatusChangedEventArgs>(watcher_StatusChanged);

            Console.WriteLine("Enter any key to quit.");
            Console.ReadLine();
        }

        static void watcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
        {
            switch (e.Status)
            {
                case GeoPositionStatus.Initializing:
                    Console.WriteLine("Working on location fix");
                    break;

                case GeoPositionStatus.Ready:
                    Console.WriteLine("Have location");
                    break;

                case GeoPositionStatus.NoData:
                    Console.WriteLine("No data");
                    break;

                case GeoPositionStatus.Disabled:
                    Console.WriteLine("Disabled");
                    break;
            }
        }
    }
}

Imports System.Device.Location

Module GetLocationEvent

    Sub ShowStatusUpdates()
        Dim Watcher As GeoCoordinateWatcher
        Watcher = New GeoCoordinateWatcher()
        watcher.Start()
        AddHandler Watcher.StatusChanged, AddressOf watcher_StatusChanged

        Console.WriteLine("Enter any key to quit.")
        Console.ReadLine()
    End Sub

    Sub watcher_StatusChanged(ByVal sender As Object, ByVal e As GeoPositionStatusChangedEventArgs)
        Select Case e.Status
            Case GeoPositionStatus.Initializing
                Console.WriteLine("Working on location fix")
            Case GeoPositionStatus.Ready
                Console.WriteLine("Have location")
            Case GeoPositionStatus.NoData
                Console.WriteLine("No data")
            Case GeoPositionStatus.Disabled
                Console.WriteLine("Disabled")
        End Select
    End Sub

    Public Sub Main()
        ShowStatusUpdates()
    End Sub
End Module

설명

이 StatusChanged 이벤트는 개체를 만든 스레드와 동일한 스레드에서 GeoCoordinateWatcher 발생합니다.
