I’m bored, so I code. Stupid extension methods that might be useful. (Probably not)

Chad Myers keeps tweeting things about dates, and it reminded me of something I read about some cool extension methods to make using dates easier. I can’t find the thing I read (mostly because I didn’t look), but I figured I’d go blog it really quick.

I wanna add some extension methods for int to make getting Dates easier. Something like this

   1:   [Test]

   2:          public void days()

   3:          {

   4:              var timespan = 1.Days();

   5:              Assert.AreEqual(1,timespan.Days);

   6:   

   7:          }

Oh, cool…. Easy to make it work too. Just like this.

   1:  public static TimeSpan Days(this int days)

   2:          {

   3:              return new TimeSpan(days,0,0,0,0);

   4:          }

Seriously though if I need to get a timespan for one day, really… Look at line 3, that’s some ugly stuff, aint it? I like the extension method.

Lets make it a little more valuable.

   1:  [Test]

   2:          public void ago()

   3:          {

   4:              var expected = DateTime.Today.AddDays(-2);

   5:              var actual = 2.Days().Ago();

   6:              Assert.AreEqual(expected,actual);

   7:          }

Simple enough to make it work, right?

   1:  public static DateTime Ago(this TimeSpan timeSpan)

   2:          {

   3:              return DateTime.Now.Subtract(timeSpan);

   4:          }

Ok, so now lets get really cute.

   1:  [Test]

   2:          public void honest_abe()

   3:          {

   4:              var expected = DateTime.Now.AddYears(-87);

   5:              var actual = 4.Score().And(7).Years().Ago();

   6:   

   7:              Assert.AreEqual(expected.Year,actual.Year);

   8:          }

Wow, I’m stupid, huh? Hehe…

Here’s what I did.

   1:   public static class DateExtensions

   2:      {

   3:          public static TimeSpan Days(this int days)

   4:          {

   5:              return new TimeSpan(days,0,0,0,0);

   6:          }

   7:          public static TimeSpan Hours(this int hours)

   8:          {

   9:              return new TimeSpan(hours,0,0);

  10:          }

  11:          public static TimeSpan Minutes(this int minutes)

  12:          {

  13:              return new TimeSpan(0,minutes,0);

  14:          }

  15:          public static TimeSpan Years(this int years)

  16:          {

  17:              var leapYears = years/4;

  18:              return new TimeSpan(365*years + leapYears, 0, 0, 0);

  19:          }

  20:          public static DateTime Ago(this TimeSpan timeSpan)

  21:          {

  22:              return DateTime.Now.Subtract(timeSpan);

  23:          }

  24:          public static int Score(this int val)

  25:          {

  26:              return val*20;

  27:          }

  28:          public static int And(this int left,int right)

  29:          {

  30:              return left + right;

  31:          }

  32:      }

Wow, what a stupid blog huh? I think my next blog post is gunna be cool though… think Amazon, think cloud, think Ellemy.CQRS and publishing…
