C# count the amount of numbers passed in the loop

I'm currently learning C# and I was trying to print out a list of numbers to the console line. The list that I want to have is as followed:

01 02 03 04 05
06 07 08 09 10
11 12 13 14 15
etc

The only problem that I'm walking against now is that I cant get a new line after 5 numbers are printed. 

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i <= 100; i++)
            {
                if (i < 10)
                {
                    Console.Write(i.ToString("00 "));
                }
                else
                {
                    Console.Write(i + " ");
                }
            }
            Console.ReadKey();
        }
    }
}

And it prints out:

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 etc

How can I make it so that after every 5 numbers a new line starts? What kind of loop or statement do I have to use in order to get this to work?

Rewrite your program as following

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i <= 100; i++)
            {
                if (i < 10)
                {
                    Console.Write(i.ToString("00 "));
                }
                else
                {
                    Console.Write(i + " ");
                }
                if (i % 5 == 0) 
                {
                    Console.WriteLine();
                }
            }
            Console.ReadKey();
        }
    }
}

A common approach is to check that the number that you have just printed is divisible by five, and print a newline if it is divisible:

if (i % 5 == 0) {
    Console.WriteLine();
}
