  使用GeoLocator插件并检查IsGeoLocationEnabled属性

  var locator = CrossGeolocator.Current;
  
  if (locator.IsGeoLocationEnabled) {
    ...
  }

  使用James montemagno的权限插件 . 可用here

  特别是下面的代码片段将帮助您：

  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;
  }
