Q:

How can i make patterns using do while loops in C#

I'm kind of a newbie when it comes to looping. :( 
please help me. 
Question:

Using a do loop, draw the following pattern:

*   
**
***
****
*****

A:

class MainClass
{
    public static void Main (string[] args)
    {
        int counter = 1;

        do {

            for (int i = 0; i < counter; i++) {
                Console.Write("*");
            }
            Console.WriteLine(); // for newline
            counter++;   // increase counter

        } while (counter < 6);
    }
}

sorry for my bad english.
You can use a counter in the do-while loop
