You really have not given enough info to "solve" the problem, but here
are some ideas you can mull around.


public class ProductList : List<Product>
{
}

public class Product
{
}

public class VegProduct : Product
{
}

public class NonVegProduct : Product
{
}

public class SuperProductList: List<ProductList>
{
}

This is just one idea. The VegProduct/NonVegProduct are not necessary if
there are no unique fields.

Another idea is to use a dictionary (or dictionary type) generic type so
you can have lists like this:

public class SuperProductList: Dictionary<string, ProductList>
{
}

You can then make the string an indicator of type of product in the
list.


Peace and Grace,
