Convert coordinates

DidarBultanov — Mon, 12 Dec 2011 09:12:04 GMT

Hi all, sorry for my bad English, I'll try to explain:)
are the coordinates of the mouse(x,y), in meters, I want to display on the map, in meters and WGS (min,sec & degress)
tell me conversion algorithm
private void MyMap_MouseClick(object sender, Map.MouseEventArgs args)
        {
            if (IdentifyGrid.IsSelected)
            {
                MapPoint clickPoint = args.MapPoint;
                MapCoordsTextBlock.Text = string.Format("X = {0}, Y = {1}", Math.Round(clickPoint.X, 4), Math.Round(clickPoint.Y, 4));
......

Please see if the following code could help you a little or not
