How to convert Arabic number to int?

use this Method

private string toEnglishNumber(string input)
{
    string EnglishNumbers = "";

    for (int i = 0; i < input.Length; i++)
    {
        if (Char.IsDigit(input[i]))
        {
            EnglishNumbers += char.GetNumericValue(input, i);
        }
        else
        {
            EnglishNumbers += input[i].ToString();
        }           
    }
    return EnglishNumbers;
}

Arabic digits like ١،٢،٣،٤ in unicode are encoded as characters in the range 1632 to 1641. Subtract the unicode for arabic zero (1632) from the unicode value of each arabic digit character to get their digital values. Multiply each digital value with its place value and sum the results to get the integer.

Alternatively use Regex.Replace to convert the string with Arabic digits into a string with decimal digits, then use Int.Parse to convert the result into an integer.

Unfortunately it is not yet possible to parse the complete string representation by passing in an appropriate IFormatProvider(maybe in the upcoming versions). However, the char type has a GetNumericValue method which converts any numeric Unicode character to a double. For example:

double two = char.GetNumericValue('٢');
Console.WriteLine(two); // prints 2

You could use it to convert one digit at a time.

A simple way to convert Arabic numbers into integer

    string EnglishNumbers="";
    for (int i = 0; i < arabicnumbers.Length; i++)
    {
        EnglishNumbers += char.GetNumericValue(arabicnumbers, i);
    }
    int convertednumber=Convert.ToInt32(EnglishNumbers);
