Hello Ramesh As I am understanding your requirement here that you want to retrive the number of products from the ' promotionproduct ' list which are equvivalent to the max property from your list. So to achive this we can do the following. 1. First we need to use an aggregate function named Max() on promotionproduct collection and store its value on a variable. 2. And then you can use Take() function on your collection with argument of the recently saved variable value of max. Please have a look on the solution. int maxCount = promotionproduct.Max(m => m.max); List filteredPromotionProducts = promotionproduct.Take(maxCount).ToList();

Hi Ramesh Please try the below code var filteredList=promotionproduct.where(x=>x.max==3).take(3).toList();
