For Octal to binary: using System; namespace IfExample { class binarytodecimal { static void Main() { Console.WriteLine(Enter a valid octal no to convert it to binary); string x = Console.ReadLine(); int decValue = Convert.ToInt32(x 8);//converting octal to decimal string retVal = Convert.ToString(decValue 2);//converting decimal to binary Console.WriteLine(binary no={0} retVal); Console.ReadLine(); } } }
