Question

Look at my code. Why does the Enumerable.Range() behave differently whether the start value is 0.

class Program
{
    static void Main(string[] args)
    {
        var range1 = Enumerable.Range(0, 7);
        PrintRange(range1);
        var range2 = Enumerable.Range(1, 8);
        PrintRange(range2);
        Console.ReadKey(true);
    }

    private static void PrintRange(IEnumerable<int> myRange)
    {
        foreach (int i in myRange)
        {
            Console.WriteLine("Linha {0}\n", i);
        }
        Console.WriteLine("\n========================================\n");
    }
}

The range itself is the same. however when it starts at 1, I get a larger one. 🙁
Here is the result:

Linha 0

Linha 1

Linha 2

Linha 3

Linha 4

Linha 5

Linha 6

========================================

Linha 1

Linha 2

Linha 3

Linha 4

Linha 5

Linha 6

Linha 7

Linha 8

========================================

Answer 1

The second argument is count not end.

Your first call is equivalent to I want 7 consecutive integers starting with 0 while the second is I want 8 consectutive integers starting with 1.
