When should I use LINQ for C#? [closed]

Answer 1

I find LINQ useful when I have a collection of some object and I'm interested in items that meet a certain criteria. Simple example would be searching for all shapes in a collection of shapes that are circles.

var circles =
        from s in allShapes
        where s.Type == ShapeTypes.Circle
        select s;

I admit I could have just written a loop with some code in it, but I find this code shorter and easier to write, and easier to read and understand.

LINQ can also be used with databases, but I actually find I don't do that very much. To each his/her own, I guess.
