How to convert numeric value in English to Marathi numeric value in C#?

Question

I am developing an windows application in C#, for that I need to convert English numeric value to Marathi numeric value. For Example. "123" = "१२३"

Answer 1

The most obviose way is use String.Replace method and write helper class.

public class MarathiHelper
{
    private static Dictionary<char, char> arabicToMarathi = new Dictionary<char, char>()
    {
      {'1','१'},
      {'2','२'},
      {'3','३'},
      {'4','४'},
      {'5','५'},
      {'6','६'},
      {'7','७'},
      {'8','८'},
      {'9','९'},
      {'0','०'},
    };

    public static string ReplaceNumbers(string input)
    {
        foreach (var num in arabicToMarathi)
        {
            input = input.Replace(num.Key, num.Value);
        }
        return input;
    }

}

And in your code you can use it like this:

var marathi = MarathiHelper.ReplaceNumbers("123");

marathi will have "१२३"

Answer 2

Well, in order to convert every character in ['0'..'9'] should be shifted by 0x0966 - '0' ; and the implementation could be

  string source = "The number is 0123456789";

  string result = new String(source
    .Select(c => c >= '0' && c <= '9' ? (Char) (c - '0' + 0x0966) : c)
    .ToArray()); 

The outcome ( result ) is

  The number is ०१२३४५६७८९

Note, that Char.IsDigit(c) is not an option here, since we don't want to shift Marathi numbers
