converting arabic date format to english : System.FormatException: 'String was not recognized as a valid DateTime.'

Question

In my c# code, I am getting an Arabic date from a function, I need to convert this date to English format (UK/US). I tried with the following code

string startdate = "٢٠١٩-٠٩-٠٣";

var dateTime = DateTime.ParseExact(
  startdate, 
 "d MMMM yyyy", 
  CultureInfo.InvariantCulture);

it throws exception:

System.FormatException: 'String was not recognized as a valid DateTime.'

Answer 1

Add this namespace using System.Globalization;

string arabicTextDate= "٢٠١٩-٠٩-٠٣";
     var str = arabicTextDate
    .Replace('\u0660','0')
    .Replace('\u0661','1')
    .Replace('\u0662','2')
    .Replace('\u0663','3')
    .Replace('\u0664','4')
    .Replace('\u0665','5')
    .Replace('\u0666','6')
    .Replace('\u0667','7')
    .Replace('\u0668','8')
    .Replace('\u0669','9');
    DateTime dt=DateTime.ParseExact(str, "yyyy-MM-dd", CultureInfo.InvariantCulture);
