How to create List

I have theese classes:

public class BaseGrid
{
    public int current { get; set; }
    public int rowCount { get; set; }
    public int total { get; set; }
    public List<T> rows { get; set; }
}

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
}

Back in my controller, I´d like to do something like:

        List<Product> listOfProducts = new List<Product>();

        BaseGrid baseGrid = new BaseGrid();
        baseGrid.rowCount = 10;
        baseGrid.total = 20;
        baseGrid.current = 1;
        baseGrid.rows = listOfProducts;

How can I do to "rows" property became a generic list and in instance in runtime the baseGrid.rows to whatever list type I want?

Thanks.
