c# LINQ: how to retrieve a single result

Question

Kind of new to linq,

whats the simplest way to retrieve a single result using linq?

example, my query

var query =
     from c in db.productIn         


        

Answer 1

use SingleOrDefault() if your query always returns only one element as result or exception will be thrown if the result of your query is more than one element.

(from c in db.productInfo
 where c.flavor == "Classic Coke" && c.container == "Can"
 select c.co2Target).SingleOrDefault();

use FirstOrDefualt() if your result more than one element and you need any one of then.

(from c in db.productInfo
 where c.flavor == "Classic Coke" && c.container == "Can"
 select c.co2Target).FirstOrDefault();
