linq - How to merge result IQueryable<T> together?

Question

If I get two result IQueryable from different linq Query and I want to merge them together and return one as result, how to to this? For example, if:

var q1 = (IQueryable<Person>).....;
var q2 = (IQueryable<Person>).....;

how to merge q1 and q2 together and get result like

var q = (IQueryable<Person>)q1.Union(q2);

Answer 1

You have it, q1.Union(q2). The Union is in the System.Linq namespace with Queryable.
