Usage

SQL Server sometimes likes storing date and times as integers, nothing else does. This fixes that.

Sure finding the day, month or year from a yyyyMMdd string (or int) isn't hard, but do you really want a bunch of SubString calls or odd looking maths cluttering your code, begging to hide bugs?

    // Find date components
    IntegerDate fromString = new IntegerDate("20180710");
    Assert.AreEqual(2018, fromString.Year);
    Assert.AreEqual(7, fromString.Month);
    Assert.AreEqual(10, fromString.Day);

    IntegerDate fromInt = new IntegerDate(20180609);
    Assert.AreEqual(2018, fromInt.Year);
    Assert.AreEqual(6, fromInt.Month);
    Assert.AreEqual(9, fromInt.Day);

    // Convert
    Assert.AreEqual(20180710, fromString.ToInt);
    Assert.AreEqual("20180609", fromInt.ToString());

    Assert.AreEqual(2018, fromInt.ToDateTime.Year);
    Assert.AreEqual(6, fromInt.ToDateTime.Month);
    Assert.AreEqual(9, fromInt.ToDateTime.Day);

    IntegerDate fromDateTime = new IntegerDate(new DateTime(2018, 07, 10));
    Assert.AreEqual(2018, fromDateTime.Year);
    Assert.AreEqual(7, fromDateTime.Month);
    Assert.AreEqual(10, fromDateTime.Day);
    Assert.AreEqual(20180710, fromDateTime.ToInt);
    Assert.AreEqual("20180710", fromDateTime.ToString());

Times stored as HHmmss in integers are a little more tricky, as they drop the leading zero for times before 10:00, but with IntegerDateTime they are simple.

    // Find date components
    IntegerTime fromString = new IntegerTime("010203");
    Assert.AreEqual(1, fromString.Hour);
    Assert.AreEqual(2, fromString.Minute);
    Assert.AreEqual(3, fromString.Second);

    IntegerTime fromInt = new IntegerTime(101112);
    Assert.AreEqual(10, fromInt.Hour);
    Assert.AreEqual(11, fromInt.Minute);
    Assert.AreEqual(12, fromInt.Second);

    // Convert
    Assert.AreEqual(10203, fromString.ToInt);
    Assert.AreEqual("101112", fromInt.ToString());

    Assert.AreEqual(10, fromInt.ToTimeSpan.Hours);
    Assert.AreEqual(11, fromInt.ToTimeSpan.Minutes);
    Assert.AreEqual(12, fromInt.ToTimeSpan.Seconds);
