How to add an item in a collection using Linq and C#

Question

I have a collection of objects. e.g.

List subscription = new List
{
    new Subscription{ Type = \"Trial\", Type = \"Offl         


        

Answer 1

I would suggest using List.Add():

subscription.Add(new Subscriptioin(...))

LINQ Union() overkill by wrapping a single item by a List<> instance:

subscriptions.Union(new List<Subscription> { new Subscriptioin(...) };

Answer 2

You don't. LINQ is for querying, not adding. You add a new item by writing:

subscription.Add(new Subscription { Type = "Foo", Type2 = "Bar", Period = 1 });

(Note that you can't specify the property Type twice in the same object initializer.)

This isn't using LINQ at all - it's using object initializers and the simple List<T>.Add method.
