Hi Great Developers,

I have written a program to find prime numbers upto the value entered by user but it is giving odd numbers too. please help me to make this program.
using System;
using System.Collections.Generic;
using System.Text;

namespace prime_numbers
{
    class Program
    {
        static void Main(string[] args)
        {
            int num;
            Console.WriteLine("enter the number upto which you want prime numbers");
            num = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("1");
            for (int i = 2; i <= num; i++)
            {
                if (i % 2 != 0)
                {
                    for (int j = 2; j <i; j++)
                    {
                        if (i % j == 0)
                        {
                            continue;
                        }
                        else
                        {
                            Console.WriteLine(i);
                            break;
                        }
                    }
                }

}
