I want to get screen X and Y values from a 'Touch' event on a SkiaSharp CanvasView. The event fires okay, but the eventargs e does not let me access the X and Y values directly. Instead, I have to dig them out of the string e.toString() as follows -

void OnTouch(object sender, EventArgs e)
     {
         string str = e.ToString();
         int index = str.IndexOf("X=");
         string strX = str.Substring(index + 2);
         index = strX.IndexOf(",");
         strX = strX.Remove(index);
         index = str.IndexOf("Y=");
         string strY = str.Substring(index + 2);
         index = strY.IndexOf("}");
         strY = strY.Remove(index);
         float X = Convert.ToSingle(strX);
         float Y = Convert.ToSingle(strY);
         offsetX += centX - X;
         if (offsetX > 2000)
             offsetX = 2000;
         else if (offsetX < -2000)
             offsetX = -2000;
         offsetY += centY - Y;

         if (!timer.Enabled)
         {
             canvasView.InvalidateSurface();
         }
     }

Here is the XAML -

<sk:SKCanvasView x:Name="canvasView" Grid.Row="1" Grid.ColumnSpan="4" PaintSurface="OnCanvasViewPaintSurface" BackgroundColor="Black" EnableTouchEvents="True" Touch="OnTouch">
</sk:SKCanvasView>

This works, but it's kind of ugly. There must be a better way.
