date comparison problem

I have a string named date . date holds date like jan 10. I want to check whether it falls betwee开发者_开发技巧n two dates or not . Example jan 10 is between dec 10 and feb 10. How can I do this task?

Convert your dates to DateTime and than use the JPLabs extension method Between.

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

namespace JpLabs.Extensions
{
    public static class ComparableExt
    {
        static public bool Between<T>(this T actual, T lower, T upper) where T : IComparable<T>
        {
            return actual.CompareTo(lower) >= 0 && actual.CompareTo(upper) < 0;
        }
    }
}

I hope it helps.

This should do it if you are using c#

public bool IsDateBetweenOtherDates(DateTime startDate,DateTime endDate, DateTime testDate)
    {
        return startDate < testDate && endDate > testDate;
    }

string date = "jan 10";
var dt = DateTime.ParseExact(date, "MMM dd", CultureInfo.InvariantCulture);
if (dt < new DateTime(dt.Year, 12, 10) && 
    dt > new DateTime(dt.Year, 2, 10))
{
     // the date is between 10 feb and 10 dec.
}

You need to use DateTime.TryParse() to turn your string into a DateTime, which can then be compared to other dates.

DateTime minDate = // minimum boundary
DateTime maxDate = // maximum boundary
string input = "January 10, 2010";
DateTime inputDate;
if (DateTime.TryParse(input, out inputDate))
{
   if (inputDate > minDate && inputDate < maxDate)
   {
      ...
   }
}

Try this:

    public bool IsDateBetweenOtherDates(DateTime startDate,DateTime endDate, DateTime testDate)
    {
        return startDate < testDate && endDate > testDate;
    }
