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";

How can I use easy way like culture info to do this please?

my sample code is:

List<string> NERKHCOlist = new List<string>();
NERKHCOlist = ScrappingFunction(NERKHCO, NERKHCOlist);
int NERKHCO_Price = int.Parse(NERKHCOlist[0]);//NERKHCOlist[0]=۱۰۳۶۷۵۱

<= So it can not Parsed it to int
And This is in my function which retun a list with persian digits inside list items

protected List<string> ScrappingFunction(string SiteAddress, List<string> NodesList)
{    
    string Price = "null";
    List<string> Targets = new List<string>();
    foreach (var path in NodesList)
    {
        HtmlNode node = document.DocumentNode.SelectSingleNode(path.ToString());//recognizing Target Node
        Price = node.InnerHtml;//put text of target node in variable(PERSIAN DIGITS)
        Targets.Add(Price);
    }
    return Targets;
}

Do you mean ***Scrapping*** or ***Scraping***? – Enigmativity Sep 18 '22 at 10:26 — Enigmativity, Sep 18 '22 at 10:26

Simply Use the code below :

private string changePersianNumbersToEnglish(string input)
{
  string[] persian = new string[10] { "۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹" };

   for (int j=0; j<persian.Length; j++)
      input = input.Replace(persian[j], j.ToString());

   return input;
 }

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();

USE Culture To convert the number from any language to any language

Functions:

public static string ConvertDigitChar(this string str, CultureInfo source, CultureInfo destination)
{
    for (int i = 0; i <= 9; i++)
    {
        str = str.Replace(source.NumberFormat.NativeDigits[i], destination.NumberFormat.NativeDigits[i]);
    }
    return str;
}

public static string ConvertDigitChar(this int digit, CultureInfo destination)
{
    string res = digit.ToString();
    for (int i = 0; i <= 9; i++)
    {
        res = res.Replace(i.ToString(), destination.NumberFormat.NativeDigits[i]);
    }
    return res;
}

How to use the functions:

var fa = CultureInfo.GetCultureInfoByIetfLanguageTag("fa");
var en = CultureInfo.GetCultureInfoByIetfLanguageTag("en");
string str = "۰0۱1۲2۳3۴4۵5۶6۷7۸8۹9";
string r1 = str.ConvertDigitChar(en, fa);
string r2 = str.ConvertDigitChar(fa, en);
int i = 123456789;
string r3 = i.ConvertDigitChar(fa);

Result:

r1: "۰۰۱۱۲۲۳۳۴۴۵۵۶۶۷۷۸۸۹۹"

r2: "00112233445566778899"

r3: "۰۱۲۳۴۵۶۷۸۹"

Useful solution, Specially using Culture, Thanks. – QMaster Feb 26 '18 at 13:51 — QMaster, Feb 26 '18 at 13:51

You need to parse them first, using e.g. Int32.Parse() with the correct cultural specifier. Once you have it as a plain integer, it's simply a matter of calling ToString() on it, again with the correct cultural specifier.

An alternative solution is to walk the string character by character and just replace any character that is a Persian digit with the corresponding (west) arabic numeral. Other characters can then be preserved as-is, if required.

If the string really contains a number, you should go with the integer parsing method. If it is not just a number, but really a phone number, serial number etc, you might need to use the replacing algorithm instead.

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.

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

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;
}

If implemented correctly, this is fastest. But you should either use a string builder, or just covert your array back to a string in the end. Also, the input string may contain other characters, so you need to test for that. — realbart, Nov 14 '21 at 09:04

You can use the Windows.Globalization.NumberFormatting.DecimalFormatter class to parse the string. This will parse strings in any of the supported numeral systems (as long as it is internally coherent).

For .Net6 or above

 public static string ConvertToNumeric(string text)
    {
        var result = new StringBuilder(text.Length);
        foreach (char ch in text)
        {
            result.Append(char.IsDigit(ch) ? char.GetNumericValue(ch) : ch.ToString());
        }
        return result.ToString();
    }
