Question

I have a list of Months displayed in a drop down. On selecting a particular month I would like to display the number of the month in a text box.

For example if I select January I would like to display it as 01, likewise for the others.

This is the sample code I have written:

string monthName = "january";
int i = DateTime.ParseExact(monthName, "MMMM", CultureInfo.CurrentCulture).Month;

Answer 1

Use this code to convert the selected Month Name into a Month Number

DateTime.ParseExact(monthName, "MMMM", CultureInfo.InvariantCulture).Month

Need String Padding?

PadleftMonthNumberString.PadLeft(2, "0")

Sample Console Application

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string mnthname = "january";
            int i = DateTime.ParseExact(mnthname, "MMMM", System.Globalization.CultureInfo.InvariantCulture).Month;
            Console.WriteLine(i.ToString());
            Console.ReadLine();
        }
    }
}
