Introduction

The Repeat operator generates a sequence by repeating a specified element a specified number of times.

Prototypes 

public static IEnumerable<T> Repeat<T>(
  T element,
  int count);

Repeat is not an extension method. It is a static method called on System.Linq.Enumerable.

Exceptions

ArgumentOutOfRangeException is thrown if the count is less than zero.

The following code will generate a sequence containing ten elements where each element is the number 2.

Demo

using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
class Program//from w  w w  .  ja v  a2s.c  o  m
{
    static void Main(string[] args)
    {
       IEnumerable<int> ints = Enumerable.Repeat(2, 10);
       foreach(int i in ints)
           Console.WriteLine(i);

    }
}
