If your query's lambda expressions reference local variables, these variables are subject to outer variable semantics.
using System;
using System.Collections.Generic;
using System.Linq;
public class MainClass {
public static void Main() {
int[] numbers = { 1, 2 };
int factor = 10;
IEnumerable<int> query = numbers.Select(n => n * factor);
factor = 20;
foreach (int n in query) Console.Write(n + "|");
}
}
