How to retrieve last 5 records using LINQ method or query expression in C#

Question

On my homepage, I want to show the recently added products. I have added a ChildAction to my controller but i am unable to understand what Linq query should i run to fetch the last five records.

Answer 1

LINQ

var lastFiveProducts = (from p in products 
                        orderby p.ProductDate descending
                        select p).Take(5);

Lambda

var lastFiveProducts = products.OrderByDescending(p => p.ProductDate).Take(5);

Which ever you prefer.

Answer 2

.Skip(count - 5);

or

.Reverse().Take(5).Reverse()

Answer 3

The simplest approach is to reverse your ordering (e.g. use orderby foo descending) and then use Take(). For example:

var recentProducts = products.OrderByDescending(x => x.CreationDate)
                             .Take(5);

or in query expression form (which I wouldn't use for simple queries which are more easily expressed in the above form):

var recentProducts = (from product in products
                      orderby product.CreationDate descending
                      select product).Take(5);

Answer 4

Install MoreLINQ Package, then:

CollectionName.TakeLast(5);

Answer 5

This is for selecting the last 5 with ascending

var query = from tbl in  (from tbl1 in object.Table orderby
tbl1.Column descending select tbl1).Take(5)  orderby tbl.Column
ascending  select tbl;

Answer 6

Code:

INT[]number = new int[] {3,6,8,2,3,7,0,2,5}

var result= (from r in number select r).reverse().take(5);

result: 5 2 0 7 3
