In this C# program, we will take input (Number of rows) from the user and print the Star (*) triangle based on the Number of rows input by the user.

C# Program to print Star (*) Triangle Code:

 private static void Main(string[] args)
        {
            int i, j, k, l, n;
            char c = '*';
            Console.Write("Enter the number of rows:");
            n = int.Parse(Console.ReadLine());
            for (i = 1; i <= n; i++)
            {
                for (j = 1; j <= n - i; j++)
                {
                    Console.Write(" ");
                }
                for (k = 1; k <= i; k++)
                {
                    Console.Write(c);
                }
                for (l = i - 1; l >= 1; l--)
                {
                    Console.Write(c);
                }
                Console.Write("\n");
            }
            Console.ReadLine();
        }
