How to get polygon all coordinates

[DevaKa]

Hi All,

I want to know how to get polygon all coordinates? I have a situation to save all coordinates. If I draw a multi-line, I have to capture all coordinates for it. When I use Client.Graphic.Extent.toString(), I am getting only 4 coordinates (If I am not wrong it might be minx,miny, maxx,maxy) when I draw rectangle and point. But I want to capture all coordinates for polygon and multiline.

thanks in Advance.

Forgive me, as this is air-code, but the logic is:

if the graphic's geometry is a polygon then 
   For each ring in the polygon's rings
        for each mappoint in the ring's pointcollection
          do something with the mappoint (like get mappoint.X and mappoint.Y) 
       next mappoint
     next ring
End if

Thanks for prompt response.

I am new to this Silverlight viewer. I didn't find any rings or mappoint or pointcollections in graphics.

A Graphic object has a Geometry property so what is described above is something like

  if ( graphic.Geometry is Polygon )
  { 
.....
  }

THe graphic's geometry.�??  not the graphic itself.

Joe, how to get coordinates for each side of polygon? I am drawing only a polygon. I want to get all coordinates of polygon.

         private void ShowPolyCoords(Graphic graphic)         {             var polygon = graphic.Geometry as Polygon;             if ( polygon == null ) return;               PointCollection points = polygon.Rings[0];             foreach (var point in points)             {                 Debug.WriteLine("X: {0}, Y: {1}", point.X, point.Y);             }         }

Thanks Joe. It works fine.
