将变量传递给另一个类

Question

我有一个xaml.cs文件，我接收经纬度并将其写入变量。 像这样

 public async void WeatherDisplay() 
      { 

       try 
       { 
        //var position = await LocationManager.GetPosition(); 
        var geoLocator = new Geolocator(); 

        Geoposition pos = await geoLocator.GetGeopositionAsync(); 
        lat = pos.Coordinate.Point.Position.Latitude; 
        lon = pos.Coordinate.Point.Position.Longitude; 
catch 
      { 

      } 
     } 

我需要这个值传递给另一个.cs文件，并将其写入到DB

这里是写DB代码。

public class CreatingBD 
    { 
     private string path = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "db.sqlite"); 
     public void Create() 
     { 
      SQLite.Net.SQLiteConnection conn = new SQLite.Net.SQLiteConnection(new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), path); 
      conn.CreateTable<DataForWeather>(); 
      conn.Insert(new DataForWeather() 
      { 
       lat = WeatherDisplay, 
       lon = lonParam 
      }); 
     } 

     public class DataForWeather 
     { 
      [PrimaryKey, AutoIncrement] 
      public int Id { get; set; } 
      public double lat { get; set; } 
      public double lon { get; set; } 
      public string city { get; set; } 
     } 

    } 

凡lat和lon是这些变量。

感谢您的帮助。

方法可以带参数。已经创造了一个长期的参数。

public void Create(double latitude, double longitude) 
{ 
    // code removed for brevity 
    double lon = longitude; 
    double lat = latitude; 
}
