获取手机定位信息（经纬度），具体地址需要结合地图Api接口进行解析
using Xamarin.Essentials; public class GeolocationPage : ContentPage { public GeolocationPage() { Button getLocationButton = new Button { Text = "Get Location" }; getLocationButton.Clicked += GetLocationButton_Clicked; Label latitudeLabel = new Label(); Label longitudeLabel = new Label(); Content = new StackLayout { Children = { getLocationButton, latitudeLabel, longitudeLabel } }; } private async void GetLocationButton_Clicked(object sender, EventArgs e) { var location = await Geolocation.GetLocationAsync(); if (location != null) { latitudeLabel.Text = $"Latitude: {location.Latitude}"; longitudeLabel.Text = $"Longitude: {location.Longitude}"; } } }
