Write a program to print prime number 1 to 100 in C#

I am sure you know answer already, Don't know why are you asking here or you can google it also it's better way

using System;
namespace LogicalPrograms
{
    public class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter The Start Number: ");
            int startNumber = int.Parse(Console.ReadLine());
            Console.Write("Enter the End Number : ");
            int endNumber = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine($"The Prime Numbers between {startNumber} and {endNumber} are : ");

            for (int i = startNumber; i <= endNumber; i++)
            {
                int counter = 0;

                for (int j = 2; j <= i / 2; j++)
                {
                    if (i % j == 0)
                    {
                        counter++;
                        break;
                    }
                }
                
                if (counter == 0 && i != 1)
                {
                    Console.Write("{0} ", i);
                }    
            }
            Console.ReadKey();
        }
    }
}

foreach (int x in Enumerable.Range(2,99))
{
    int isPrime = 0;
    for (int y = 1; y < x; y++)
    {
        if (x % y == 0)
            isPrime++;

        if (isPrime == 2) break;
    }
    if (isPrime != 2)
        Console.WriteLine(x + " ");
}
Console.ReadKey();
