Get sum of two columns in one LINQ query

Question

let's say that I have a table called Items (ID int, Done int, Total int)

I can do it by two queries:

int total = m.Items.Sum(p=>p.Total) int done = m.Items.Sum(p=>p.Done) 

But I'd like to do it in one query, something like this:

var x = from p in m.Items select new { Sum(p.Total), Sum(p.Done)}; 

Surely there is a way to call aggregate functions from LINQ syntax...?

Answer 1

This will do the trick:

from p in m.Items group p by 1 into g select new {     SumTotal = g.Sum(x => x.Total),      SumDone = g.Sum(x => x.Done)  };
