entity framework - DbGeography polygon get points -

i have polygon persisted on sql server 2012 database sys.geography type. how can obtain points polygon?

i'm thinking use astext() method , parse string, maybe there better choice?

found way, here extension method:

public static ienumerable<myentitywithlatandlng> getpointsfrompolygon(this system.data.entity.spatial.dbgeography geo) {    (int = 1; < geo.pointcount; i++)    {      var p = geo.pointat(i);      yield return new myentitywithlatandlng(){ latitude = p.latitude.value, longitude = p.longitude.value };   } }
