Question

I have a table like below

   Customers  
   Id jan feb mar apr.........dec  
   1   10 12  12  10 .........40   
   2   11 13  12  10 .........42  

I want to write Linq Expression to return order by total(jan+feb…dec) desc
I want something like customers.OrderbyDesc(p=>Sum(p.jan,p.feb,.p.dec).

Note: There is no total column at the end.
If there is a way I can project the sum into temp variable and then sort it?

Answer 1

Sure – something like:

var ordered = customers.OrderByDescending(p => p.jan + p.feb + p.mar + ...);

You don’t need to use Sum here… just normal addition.
