Deon (previously) has some good news. His contract at Initrode is over, and he’s on his way out the door. But before he goes, he wants to share more of his pain with us.
You may remember that the StringManager class had a bunch of data type conversions to numbers and dates. Well guess what, there’s also a DateManager class, which is another 1600 lines of methods to handle dates.
As you might expect, there are a pile of re-invented conversion and parsing methods which do the same thing as the built-in methods. But there’s also utility methods to help us handle date-related operations.
public static int subStractFromCurrentDate(System.DateTime dateTimeParm)
{
//get now
System.DateTime now = System.DateTime.Now;
//now compare days
int daysDifference = now.Day - dateTimeParm.Day;
return daysDifference ;
}Fun fact: the Day property returns the day of the month. So this method might “subStract”, but if these two dates fall in different months, we’re going to get unexpected results.
One of the smaller string formatters included is this one:
public static string formatEnglishDate (System.DateTime inputDateTime)
{
Hashtable _monthsInEnglishByMonthNumber = new Hashtable();
_monthsInEnglishByMonthNumber[1] = "January";
_monthsInEnglishByMonthNumber[2] = "February";
_monthsInEnglishByMonthNumber[3] = "March";
_monthsInEnglishByMonthNumber[4] = "April";
_monthsInEnglishByMonthNumber[5] = "May";
_monthsInEnglishByMonthNumber[6] = "June";
_monthsInEnglishByMonthNumber[7] = "July";
_monthsInEnglishByMonthNumber[8] = "August";
_monthsInEnglishByMonthNumber[9] = "September";
_monthsInEnglishByMonthNumber[10] = "October";
_monthsInEnglishByMonthNumber[11] = "November";
_monthsInEnglishByMonthNumber[12] = "December";
StringBuilder _dateBldr = new StringBuilder();
_dateBldr.Append(_monthsInEnglishByMonthNumber[inputDateTime.Month].ToString());
_dateBldr.Append(" ");
_dateBldr.Append(inputDateTime.Day.ToString());
_dateBldr.Append(", ");
_dateBldr.Append(inputDateTime.Year.ToString());
return _dateBldr.ToString();
}Among all the bad things implied here, I really like that they used a Hashtable as an array.
public static bool currentDateIsFirstBusinessDateOfTheMonth
(
Hashtable inputHolidayHash
)
{
/*
* If current date is not a business date, then it cannot
* be the first business date of the month.
*/
DateTime _currentDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);
_currentDate =
new DateTime(2010, 5, 6);
if (
_currentDate.DayOfWeek == DayOfWeek.Saturday
||
_currentDate.DayOfWeek == DayOfWeek.Sunday
||
inputHolidayHash[_currentDate] != null
)
return false;
/*
* If current date is a business date, and if it is also
* the first calendar date of the month, then the
* current date is the first business date of the month.
*/
DateTime _firstDayOfTheMonth =
_currentDate.AddDays(1 - _currentDate.Day);
if (_firstDayOfTheMonth == _currentDate)
return true;
/*
* If current date is a business date, but is not the 1st calendar
* date of the month, and, if, in stepping back day by day
* from the current date, we encounter a business day before
* encountering the last calendar day of the preceding month, then the
* current date is NOT the first business date of the month.
*/
DateTime _tempDate = _currentDate.AddDays(-1);
while (_tempDate >= _firstDayOfTheMonth)
{
if (
_tempDate.DayOfWeek != DayOfWeek.Saturday
&&
_tempDate.DayOfWeek != DayOfWeek.Sunday
&&
inputHolidayHash[_tempDate] == null
)
return false;
_tempDate = _tempDate.AddDays(-1);
}
/*
* * If current date is a business date, but is not the 1st calendar
* date,and, if, in stepping back day by day from the current date,
* we encounter no business day before encountering the
* 1st calendar day of the month, then the current date
* IS the first business date of the month.
*/
return true;
}This one has loads of comments, and honestly, I still have no idea what it’s doing. If it’s checking the current day, why does it need to cycle through other days? Why even ask that question, because clearly while debugging they hard-coded a testing date (new DateTime(2010, 5, 6)) and just left that in there.
I’m not the only one getting confused. Check out this comment:
//@??
public static DateTime givenPeriodEndDateFindLastBusinessDateInPeriod
(
DateTime inputPeriodEndDate
, Hashtable inputHolidayHash
)
{
...
}And if you’re missing good old StringManager, don’t worry, we use it here:
/**
* @description format date
* */
public static string formatYYYYMMDD (System.DateTime inputDateTime)
{
StringBuilder _bldr = new StringBuilder();
_bldr.Append(inputDateTime.Year.ToString());
_bldr.Append(initrode.utilities.StringManager.Fill(inputDateTime.Month.ToString(),
"0", // Zero-Fill
true, // Fill from left
2)); // String length
_bldr.Append(initrode.utilities.StringManager.Fill(inputDateTime.Day.ToString(),
"0", // Zero-Fill
true, // Fill from left
2)); // String length
return _bldr.ToString();
}And all of this is from just about the first third of the code. I’m trying to keep to shorter methods before posting the whole blob of ugly. So with that in mind, what if you wanted to compare dates?
public static DateComparison date1ComparedToDate2(DateTime inputDate1,
DateTime inputDate2)
{
if (inputDate1.Year > inputDate2.Year) return DateComparison.gt;
if (inputDate1.Year < inputDate2.Year) return DateComparison.lt;
if (inputDate1.DayOfYear > inputDate2.DayOfYear) return DateComparison.gt;
if (inputDate1.DayOfYear < inputDate2.DayOfYear) return DateComparison.lt;
return DateComparison.eq;
}Oh yeah, not only do we break the dates up into parts to compare them, we also have a custom enumerated type to represent the result of the comparison. And it’s not just dates, we do it with times, too.
public static DateComparison timestamp1ComparedToTimestamp2(DateTime inputTimestamp1,
DateTime inputTimestamp2)
{
if (inputTimestamp1.Year > inputTimestamp2.Year) return DateComparison.gt;
if (inputTimestamp1.Year < inputTimestamp2.Year) return DateComparison.lt;
if (inputTimestamp1.DayOfYear > inputTimestamp2.DayOfYear) return DateComparison.gt;
if (inputTimestamp1.DayOfYear < inputTimestamp2.DayOfYear) return DateComparison.lt;
if (inputTimestamp1.Hour > inputTimestamp2.Hour) return DateComparison.gt;
if (inputTimestamp1.Hour < inputTimestamp2.Hour) return DateComparison.lt;
if (inputTimestamp1.Minute > inputTimestamp2.Minute) return DateComparison.gt;
if (inputTimestamp1.Minute < inputTimestamp2.Minute) return DateComparison.lt;
if (inputTimestamp1.Second > inputTimestamp2.Second) return DateComparison.gt;
if (inputTimestamp1.Second < inputTimestamp2.Second) return DateComparison.lt;
if (inputTimestamp1.Millisecond > inputTimestamp2.Millisecond) return DateComparison.gt;
if (inputTimestamp1.Millisecond < inputTimestamp2.Millisecond) return DateComparison.lt;
return DateComparison.eq;
}Initrode has a bright future with this product. Deon adds:
The contractor who is replacing me has rolled his own piece of software to try and replace Entity Framework because his version is “better” despite being written around a decade ago, so I’m sure he’ll fit right in.
The future’s so bright I’ve gotta wear shades.
