我想创建一个简单的控制台应用程序,它将检索计算机的坐标。我真的不知道如何在计算机上启用位置服务.. 到目前为止,我的代码看起来像这样:
GeoCoordinateWatcher watcher = new GeoCoordinateWatcher();
watcher.TryStart(false, TimeSpan.FromSeconds(10));
GeoCoordinate CurrentCoordinate = watcher.Position.Location;
if (CurrentCoordinate.IsUnknown)
{
Console.WriteLine("At this time, your coordinates are unknown..\n");
Console.WriteLine("Do you want to force the program to find your coordinates?\n(Y = yes, All Any Other Key = no)");
ConsoleKeyInfo KPress = Console.ReadKey(false);
if (KPress.Key == ConsoleKey.Y)
{
/*
Enabling The Location Services & Find The User's Location Coordinates
*/
GeoCoordinate NewCoord = ReFindCoordinates(watcher);
Console.WriteLine("Latitude: " + NewCoord.Latitude);
Console.WriteLine("Longtitude: " + NewCoord.Longitude);
}
else
{
Environment.Exit(0);
}
}
else
{
Console.WriteLine("Latitude: " + CurrentCoordinate.Latitude);
Console.WriteLine("Longtitude: " + CurrentCoordinate.Longitude);
}
有人知道如何通过C#启用此服务吗?我很乐意得到一些帮助.. 谢谢。

从网上抓取地理位置?
internal GeoLoc GetMyGeoLocation()
{
try
{
//create a request to geoiptool.com
var request = WebRequest.Create(new Uri("http://geoiptool.com/data.php")) as HttpWebRequest;
if (request != null)
{
//set the request user agent
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727)";
//get the response
using (var webResponse = (request.GetResponse() as HttpWebResponse))
if (webResponse != null)
using (var reader = new StreamReader(webResponse.GetResponseStream()))
{
//get the XML document
var doc = new XmlDocument();
doc.Load(reader);
//now we parse the XML document
var nodes = doc.GetElementsByTagName("marker");
Guard.AssertCondition(nodes.Count > 0,"nodes",new object());
//make sure we have nodes before looping
//if (nodes.Count > 0)
//{
//grab the first response
var marker = nodes[0] as XmlElement;
Guard.AssertNotNull(marker, "marker");
var _geoLoc = new GeoLoc();
//get the data and return it
_geoLoc.City = marker.GetAttribute("city");
_geoLoc.Country = marker.GetAttribute("country");
_geoLoc.Code = marker.GetAttribute("code");
_geoLoc.Host = marker.GetAttribute("host");
_geoLoc.Ip = marker.GetAttribute("ip");
_geoLoc.Latitude = marker.GetAttribute("lat");
_geoLoc.Lognitude = marker.GetAttribute("lng");
_geoLoc.State = GetMyState(_geoLoc.Latitude, _geoLoc.Lognitude);
return _geoLoc;
//}
}
}
// this code would only be reached if something went wrong
// no "marker" node perhaps?
return new GeoLoc();
}
catch (Exception ex)
{
throw;
}
}

为什么不直接使用Bing Maps API并从他们的网络服务获取您的位置? http://msdn.microsoft.com/en-us/library/ff701713.aspx

使用GeoCoordinateWatcher课程时,检索位置会有一些延迟。因此,您可以挂钩 watcher_PositionChanged 事件并从那里获取位置。希望这有帮助
_watcher = new GeoCoordinateWatcher();
_watcher.TryStart(true, TimeSpan.FromMilliseconds(1000));
_watcher.PositionChanged += watcher_PositionChanged;
void watcher_PositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e)
{
if (e.Position.Location != null)
{
Console.WriteLine("Lat: {0}, Long: {1}",
e.Position.Location.Latitude,
e.Position.Location.Longitude);
_watcher.Stop();
}
}
