This sample code will help in your lab assignment to convert a octal number to decimal number.

Suppose we have to convert 234 octal number to decimal number, so you have to write it

2*(8^2) + 3*(8^1) + 4*(8^0)

 

C# Code to convert Octal to Decimal:

using System;
using System.Collections.Generic;
using System.Text;

namespace TestConsole
{
    class Octal2Decimal
    {
        static void Main(string[] args)
        {

            int DecimalNumber = 0;
            int OctalNumber;
            int power = 1;
            Console.WriteLine("Please enter Octal number:");
            OctalNumber = Convert.ToInt32(Console.ReadLine());

            while (OctalNumber > 0)
            {
                DecimalNumber += OctalNumber % 10 * power;
                OctalNumber = OctalNumber / 10;
                power = power * 8;
            }

            Console.WriteLine("The decimal equilavent is {0}", OctalNumber);
            Console.ReadLine();
        }
    }
}
