Export graphic layer to KML file and shapefile

[cocococo]

Is it possible to export graphic layer to KML file and shapefile with API version 2.1 and Silverlight 4? Can anyone suggest me the way how to do?

Thank you for your help.

I would also like some direction on this.

I believe to export to Shape File you'll have to create a geoprocessing service that will create the Shape File on the server side, zip up the files and return them to the client.
