实现
示例
以下示例处理 StatusChanged 事件并基于 Status输出消息。
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;
}
}
}
}
