Binary to decimal using C#

CsharpServer Side ProgrammingProgramming

To convert binary to decimal, here I have used a while loop and found the remainder of the Binary number, which is the input. After that, the remainder is multiplied by the base value and added.

This is what I did to get the decimal value −

while (val > 0) {
   remainder = val % 10;
   myDecimal = myDecimal + remainder* baseVal;
   val = val / 10;
   baseVal = baseVal * 2;
}

Example

Let us see the complete code to convert binary to decimal in C# −

Live Demo

using System;
using System.Collections.Generic;
using System.Text;
namespace Demo {
   class toBinary {
      static void Main(string[] args) {
         int val = 1010, myBinary, remainder;
         int myDecimal = 0, baseVal = 1;
         myBinary = val;
         while (val > 0) {
            remainder = val % 10;
            myDecimal = myDecimal + remainder * baseVal;
            val = val / 10;
            baseVal = baseVal * 2;
         }
         Console.Write("Binary Number : " + myBinary);
         Console.Write("\nConverted to Decimal: " + myDecimal);
         Console.ReadLine();
      }
   }
}

Output

Binary Number : 1010
Converted to Decimal: 10
