How to Convert Persian Digits in variable to English Digits Using Culture?

Question

I want to change persian numbers which are saved in variable like this :

string Value=\"۱۰۳۶۷۵۱\"; 

to

string Value=\"1036751\"         


        

Answer 1

use this static class to change normalize number easily:

public static class Numbers
{
    public static string ChangeToEnglishNumber(this string text)
    {
        var englishNumbers = string.Empty;
        for (var i = 0; i < text.Length; i++)
        {
            if(char.IsNumber(text[i])) englishNumbers += char.GetNumericValue(text, i);
            else englishNumbers += text[i];
        }

        return englishNumbers;
    }
}

Sample:

string test = "۱۰۳۶۷۵۱".ChangeToEnglishNumber(); // => 1036751

Answer 2

You can manually convert them like so

    char[][] numbers = new char[][]
    {
        "0123456789".ToCharArray(),"persian numbers 0-9 here".ToCharArray()
    };
    public void Convert(string problem)
    {
        for (int x = 0; x <= 9; x++)
        {
            problem.Replace(numbers[0][x], numbers[1][x]);
        }
    }

I don't know the persian numbers so you will have to add them into the char array.

Answer 3

Useful and concise:

public static class Utility
    {
        // '۰' = 1632
        // '0' = 48
        // ------------
        //  1632  => '۰'
        //- 1584
        //--------
        //   48   => '0'
        public static string GetEnglish(this string input)
        {
            char[] persianDigitsAscii = input.ToCharArray(); //{ 1632, 1633, 1634, 1635, 1636, 1637, 1638, 1639, 1640, 1641 };
            string output = "";
            for (int k = 0; k < persianDigitsAscii.Length; k++)
            {
                persianDigitsAscii[k] = (char) (persianDigitsAscii[k] - 1584);
                output += persianDigitsAscii[k];
            }

             return output;
        }
    }

Answer 4

I suggest two approaches to handle this issue(I Create an extension method for each of them):

1.foreach and replace

public static class MyExtensions
{
     public static string PersianToEnglish(this string persianStr)
     {
            Dictionary<char, char> LettersDictionary = new Dictionary<char, char>
            {
                ['۰'] = '0',['۱'] = '1',['۲'] = '2',['۳'] = '3',['۴'] = '4',['۵'] = '5',['۶'] = '6',['۷'] = '7',['۸'] = '8',['۹'] = '9'
            };
            foreach (var item in persianStr)
            {
                persianStr = persianStr.Replace(item, LettersDictionary[item]);
            }
            return persianStr;
     }
}

2.Dictionary.Aggregate

public static class MyExtensions
{
      public static string PersianToEnglish(this string persianStr)
      {
            Dictionary<string, string> LettersDictionary = new Dictionary<string, string>
            {
                ["۰"] = "0",["۱"] = "1",["۲"] = "2",["۳"] = "3",["۴"] = "4",["۵"] = "5",["۶"] = "6",["۷"] = "7",["۸"] = "8",["۹"] = "9"
            };
            return LettersDictionary.Aggregate(persianStr, (current, item) =>
                         current.Replace(item.Key, item.Value));
      }
}

Usage:

string result = "۱۰۳۶۷۵۱".PersianToEnglish();

Answer 5

Here my code convert Persian digits in variable to English , By extension method(Can use with dot after your expression)

private static readonly string[] pn = { "۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹" };
    private static readonly string[] en = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };
    public static string ToEnglishNumber(this string strNum)
    {
        string chash = strNum;
        for (int i = 0; i < 10; i++)
            chash = chash.Replace(pn[i], en[i]);
        return chash;
    }
    public static string ToEnglishNumber(this int intNum)
    {
        string chash = intNum.ToString();
        for (int i = 0; i < 10; i++)
            chash = chash.Replace(pn[i], en[i]);
        return chash;
    }

and when you want to use this code have to write : txt1.Value.ToEnglishNumber();

Answer 6

The Saeed's Solution is Ok,But For Double Variables you Must Also replace "٫" Character To "." , So You Can Use :

private string ToEnglishNumber(string strNum)
{
string[] pn = { "۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹", "٫" };
string[] en = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9","." };
string chash = strNum;
for (int i = 0; i < 11; i++)
    chash = chash.Replace(pn[i], en[i]);
return chash;
}
