获取设备位置并在地图上设置位置

Question

我正在处理一个项目，在该项目中获取设备位置并找到附近的标记。我无法在网上找到任何方式将我的位置转换为地理点。

public async void GetPosition() { 
    Geolocator geolocator = new Geolocator { DesiredAccuracyInMeters = 0 }; 
    Geoposition geoposition = await geolocator.GetGeopositionAsync(); 

    // Needs to be converted to Geopoint 
    // Call UpdateLocationData 
} 

public async void UpdateLocationData(Geopoint geopoint) { 
    await MapControl1.TrySetViewAsync(geopoint); 
} 

我想这个代码，我发现：

// Reverse Geocoding 
BasicGeoposition myLocation = new BasicGeoposition { 
    Longitude = position.Coordinate.Longitude, 
    Latitude = position.Coordinate.Latitude 
}; 

Geopoint pointToReverseGeocode = new Geopoint(myLocation); 

但它说，Coordinate.Longitude.get上的Visual Studio 2015年RC过时。

这是一个朋友，我放在一起使用JavaScript地理定位。

function getLocation() 
{ 
//Check for geolocation support in browser 
if (navigator.geolocation) { 
    //getCurrentPosition(function for success, function for error); 
    //getCurrentPosition creates a variable named position which has several properties 
    navigator.geolocation.getCurrentPosition(displayLocation, displayError, {maximumAge:600000, timeout:5000, enableHighAccuracy: true}); 
} else { 
    //Statement for testing else statement and error handling 
    document.getElementById('coordinates').innerHTML = "Browser unable to support geolocation."; 
} 
} 

//The argument for displayLocation is a variable created by getCurrentLocation 
function displayLocation(position) 
{ 
//Variables to track position 
var lati = position.coords.latitude; 
var longi = position.coords.longitude; 
//If getCurrentPosition is successful/true 
alert("Your position has been identified."); 
//Displays coordinates 
document.getElementById('coordinates').innerHTML = "Latitude: " + lati + " | Longitude: " + longi; 
//Displays coordinates on map 
showMap(position); 
} 

function displayError() 
{ 
//If getCurrentPosition fails/false 
alert("Unable to locate your position."); 
document.getElementById('coordinates').innerHTML = "Unable to locate your position."; 
} 

function showMap(position) 
{ 
//Variables to track position 
var lati = position.coords.latitude; 
var longi = position.coords.longitude; 
var imageURL= "http://maps.googleapis.com/maps/api/staticmap?center=" + lati + "," + longi + "&zoom=14&size=500x375&sensor=false"; 
document.getElementById('map').innerHTML = "<img src='" + imageURL + "'>"; 
}
