C# - Number System - Conversion - Convert Decimal to any Base (Hexadecimal, Octal, Binary and any other)

This program converts a decimal number to any base. For example, convert from decimal to hexadecimal, convert from decimal to octal, convert from decimal to binary etc.

CODE

using System; class Program { public static void Main(string[] args) { int inputNumber = 1234; int baseToConvert = 16; //call the function string convertedNumber = ConvertDecimalToAnyBase(inputNumber, baseToConvert); Console.WriteLine("Decimal Input: " + inputNumber); Console.WriteLine("Base " + baseToConvert + " : " + convertedNumber); Console.ReadKey(); } static string ConvertDecimalToAnyBase(int decimalNumber, int baseToConvert) { string convertedNumber = ""; if (decimalNumber == 0) //if the number is 0, return 0 convertedNumber = decimalNumber.ToString(); else { //the loop will iterate as long as decimalNumber > 0 //the value of decimalNumber will be changed inside the loop while (decimalNumber > 0) { //get the remainder int remainder = decimalNumber % baseToConvert; //convert the remainder to its corresponding character string remainderCharacter = ""; if (remainder >= 0 && remainder <= 9) //if remainder is between 0 and 9, return the same remainderCharacter = remainder.ToString(); else { //if remainder is greater than 9, convert as A, B etc //ASCII 65 = A, 66 = B etc //get the ASCII value using the expression below. int asciiValue = remainder - 10 + 65; //convert the ascii to its corresponding character remainderCharacter = ((char)asciiValue).ToString(); } //prefix the remainderCharacter to the result convertedNumber = remainderCharacter + convertedNumber; //get the quotient decimalNumber = decimalNumber / baseToConvert; } } return convertedNumber; } }
