Search in array Learn programming C#

Lesson:

Arrays, Structures and Strings

Exercise:

Search in array

Objetive:

Create a C# program that says if a data belongs in a list that was previously created.

The steps to take are:
- Ask the user how many data will he enter.
- Reserve space for that amount of numbers (floating point).
- Request the data to the user
- Later, repeat:
* Ask the user for a number (execution ends when he enters "end" instead of a number).
* Say if that number is listed or not.

Must be done in pairs. but you must provide a single source file, containing the names of both programmers in a comment.

Code:

using System;
public class exercise73
{
    public static void Main()
    {
        Console.Write("Cuantos datos reservo: ");
        int repeticiones = Convert.ToInt32(Console.ReadLine());
        float numero;
        float[] listaNumeros = new float[repeticiones];

        for (int i = 1; i <= repeticiones; i++)
        {
            Console.Write("Dime numero {0} para guardar en la lista: ", i);
            listaNumeros[i] = Convert.ToSingle(Console.ReadLine());
        }

        Console.Write("Que numero comprueba en la lista? ");
        numero = Convert.ToSingle(Console.ReadLine());

        while (Console.ReadLine() != "end")
        {
            for (int i = 1; i <= repeticiones; i++)
            {
                if (listaNumeros[i] == numero)
                    Console.WriteLine("El número {0} existe en la lista", numero);
            }
        }
    }
}
