In LINQ, the Range() method is used to generate the list of integers or numbers based on specified values of start index and end index.

Syntax

Range(start_index, end_index)

Example

using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
 public static void Main()
 {
  List<int> range = Enumerable.Range(50,50).ToList(); 
  Console.WriteLine('Prime List ');
  range.ForEach(item => Console.Write('{0}', IsPrime(item) ? item+', ' : ''));

  Console.WriteLine('\b\b ');
 }

 public static bool IsPrime(int num){
  for(int i=2;i<Math.Sqrt(num);i++)
   if(num % i ==0 )
    return false;
 return true; 
 }

}

Output

Prime List 
53, 59, 61, 67, 71, 73, 79, 83, 89, 97
