The Repeat method is used to generate a collection or list with the same number as repeated times based on specified index values.

Syntax

Enumerable.Repeat<int>(start, times);

Example

using System;

using System.Collections.Generic;

using System.Linq;

public class Program

{

 public static void Main()

 {

  IEnumerable<int> range = Enumerable.Repeat<int>(50,10); 

  long sum = range.Aggregate((a,b) => a+b);

  Console.WriteLine('List ');

  range.ToList().ForEach(item => Console.Write('{0}, ',item));

  Console.WriteLine('\nSum : '+sum);

 }

 public static bool IsPrime(int num){

  for(int i=2;i<Math.Sqrt(num);i++)

   if(num % i ==0 )

    return false;

 return true; 

 }

}

Output

List 

50, 50, 50, 50, 50, 50, 50, 50, 50, 50, 

Sum : 500
