Try this:

using System;

class Program
{
static void Main()
{
for(int i = 1; i <= 5; i++)
{
Console.WriteLine(new string('*', i));
}

Console.ReadKey();
}
}

Dear All.
This is dynamic row what I Posted.Interviewer always expect Dynamic row.Not Static.

class Program
{
public void Display(int noofrow)
{
for ( int i = 1; i <= noofrow; i++)
{
Console.WriteLine(new string('*', i));
}
}
static void Main(string[] args)
{
Console.WriteLine("Enter Number of Row you want to Display");
int NoofRow = Convert.ToInt32(Console.ReadLine());
Program p = new Program();
p.Display(NoofRow);
Console.ReadLine();
}
}
