Convert unicode digits from english to devanagari

Question

I was looking for some RegEx or any other method to convert digits 0-9 into ०-९ (devanagari script). I am using asp.net but could not find any method in globalization namespace which does this.

Any help is greatly appreciated.

Answer 1

Found similar post here!

My solution is bit different though as I know the source and destination culture. So I can hard-code the digits array.

        string devYear = "";
        string[] devD = { "०", "१", "२", "३", "४", "५", "६", "७", "८", "९" };
        char[] digits = curYear.ToCharArray();
        foreach (char ch in digits)
        {
            devYear += devD[int.Parse(ch.ToString())];
        }

Another change is that I am iterating through the year digits instead of devD array. Saves few iterations as most numbers will be less than 10 digit. In my case, only four digits.

Hopefully will be useful for someone stuck up on similar lines.

Answer 2

Does each latin digit 0..9 map to exactly a devanagari digit (I do think so, if I understand Wikipedia correctly)=

If yes, how about the following:

public static string ConvertDigits( string s )
{
    return s
        .Replace("0", "०")
        .Replace("1", "१")
        .Replace("2", "२")
        .Replace("3", "३")
        .Replace("4", "४")
        .Replace("5", "५")
        .Replace("6", "६")
        .Replace("7", "७")
        .Replace("8", "८")
        .Replace("9", "९");
}

For optimization, you could check for string.IsNullOrEmpty() before calling the string.Replace function.

In Addition (if this is suitable for a devanagari digit), call the string.Replace() function overload that takes chars as parameters rather than strings.
