C# Programming Question

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();
        }
    }
}

Hi,

For binary to decimal

try this:

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

namespace IfExample
{
  class binarytodecimal
  {
  static void Main()
  {
  Console.WriteLine("Enter a binary no to convert it to decimal");
  string x = Console.ReadLine();
  Console.WriteLine("decimal no={0}",Convert.ToInt32(x, 2).ToString());
  Console.ReadLine();
  }
  }
}

Hi, follow the code

 Decimal to Binary conversion:
 int decimalNum = 42;
 string binaryNum = Convert.ToString(decimalNum, 2);

 Binary To Decimal conversion:
 string binaryNum  = "101";
 int decimalNum = Convert.ToInt32(binaryNum , 2);
