通过Xamarin.Forms中的C#检查Android设备中是否启用了位置权限

我正在创建一个应用程序，并且我正在尝试在我的Android应用程序的设备（在设置中）中获取位置权限。我正在使用Xamarin.Forms。如何通过Xamarin中的C#实现这一点？

使用插件并检查IsGeoLocationEnabled属性

var locator = CrossGeolocator.Current;

if (locator.IsGeoLocationEnabled) {
  ...
}

使用James montemagno提供的权限插件。可用

特别是以下代码片段将帮助您：

try {
 var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Location);
 if (status != PermissionStatus.Granted) {
  if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Location)) {
   await DisplayAlert("Need location", "Gunna need that location", "OK");
  }
  var results = await CrossPermissions.Current.RequestPermissionsAsync(new [] {
   Permission.Location
  });
  status = results[Permission.Location];
 }
 if (status == PermissionStatus.Granted) {
  var results = await CrossGeolocator.Current.GetPositionAsync(10000);
  LabelGeolocation.Text = "Lat: " + results.Latitude + " Long: " + results.Longitude;
 } else if (status != PermissionStatus.Unknown) {
  await DisplayAlert("Location Denied", "Can not continue, try again.", "OK");
 }
} catch (Exception ex) {
 LabelGeolocation.Text = "Error: " + ex;
}
