I have a following problem... I am looking for best and efficient solution 
for this problem.

I have following entities ..(c#)

public class Dog 
{
.... some Properties and methods.....

Dogs _friendDogs = new Dogs() ;

Public Dogs Friends()
{
 get
            {
                return _friendDogs;
            }
            set
            {
                _friendDogs= value;
            }

	}
      
}

Public class Dogs : CollectionBase 
{
........
}



When I am working with Dog and Dogs its is working fine without any error in 
same project but when I am passing this entity through web service 
I get an error because webservice convert this dogs to some array list and 
cant be converted back to entity.



[WebMethod]
public Dogs GetFriendsDog()
{
.......
Return Dogs

}

Problem comes here on the following last line 

Dogs  somedogs = new Dogs();

somedogs = somewebService.GetFriendsDog() ;



Please suggest best method for this.

Kishor
