如何利用c#获取当前位置的经纬度
如何利用c#获取当前位置的经纬度
提问于 2015-05-18 07:23:04
我是c#的新手，我试着得到当前位置的纬度和经度。下面是我尝试过的代码。
码
public string GetLocationProperty()
{
double a = 0.0;
string b = "";
GeoCoordinateWatcher watcher = new GeoCoordinateWatcher();
// Do not suppress prompt, and wait 1000 milliseconds to start.
watcher.TryStart(false, TimeSpan.FromMilliseconds(1000));
GeoCoordinate coord = watcher.Position.Location;
if (coord.IsUnknown != true)
{
//Console.WriteLine("Lat: {0}, Long: {1}",
// coord.Latitude,
// coord.Longitude);
a = coord.Latitude;
b = a.ToString();
}
else
{
Console.WriteLine("Unknown latitude and longitude.");
}
return b;

这就是你要的
GeoCoordinateWatcher watcher= new GeoCoordinateWatcher(GeoPositionAccuracy.Default);
watcher.Start(); //started watcher
GeoCoordinate coord = watcher.Position.Location;
if (!watcher.Position.Location.IsUnknown)
{
double lat = coord.Latitude; //latitude
double long = coord.Longitude; //logitude

使用此代码获取当前用户位置。
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();
Console.ReadKey();

GeoCoordinateWatcher _geoWatcher = new GeoCoordinateWatcher();
_geoWatcher.PositionChanged += GeoWatcher_PositionChanged;
bool isStarted = _geoWatcher.TryStart(suppressPermissionPrompt, timeOut);
_currentLocation = (isStarted && !_geoWatcher.Position.Location.IsUnknown) ? _geoWatcher.Position.Location: new GeoCoordinate();
private void GeoWatcher_PositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e)
{
_currentLocation = e.Position.Location;
_geoWatcher.Stop();
