    public static string ToEnglishNumber(string input)

        var englishnumbers = new Dictionary<string, string>()
        {
            {"۰","0" }, {"۱","1" }, {"۲","2" }, {"۳","3" },{"۴","4" }, {"۵","5" },{"۶","6" }, {"۷","7" },{"۸","8" }, {"۹","9" },

Use this extension ,also for arabic keyboard for example : "۵", "٥" or "۴", "٤"

static char[][] persianChars = new char[][]
    {
        "0123456789".ToCharArray(),"۰۱۲۳۴۵۶۷۸۹".ToCharArray()
    };
    static char[][] arabicChars = new char[][]
    {
        "0123456789".ToCharArray(),"٠١٢٣٤٥٦٧٨٩".ToCharArray()
    }; 
    public static string toPrevalentDigits(this string src)
    {
        if (string.IsNullOrEmpty(src)) return null;
        for (int x = 0; x <= 9; x++)
        {
            src = src.Replace(persianChars[1][x], persianChars[0][x]);
        }
        for (int x = 0; x <= 9; x++)
        {
            src = src.Replace(arabicChars[1][x], arabicChars[0][x]);
        }
        return src;
    }

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).
