Is there a predefined enumeration for Month in the .NET library?

Question

I'm looking to see if there is an official enumeration for months in the .net framework.

It seems possible to me that there is one, because of how common the use of month is, and because there are other such enumerations in the .net framework.

For instance, there is an enumeration for the days in the week, System.DayOfWeek, which includes monday, tuesday, etc..

I'm wondering if there is one for the months in the year, ie. January, February, etc?

Does anyone know?

Thanks for reading!

Answer 1

No, there isn't.

Answer 2

There isn't, but if you want the name of a month you can use:

CultureInfo.CurrentCulture.DateTimeFormat.GetMonth ( DateTime.Now.Month );

which will return a string representation (of the current month, in this case). Note that GetMonth takes arguments from 1 to 13 - January is 1, 13 is a blank string.

Answer 3

I don't know for sure, but my hunch is no. DateTime.Month returns an integer. If there was such an enumeration, it would probably be returned by DateTime.

Answer 4

What exactly are you attempting to accomplish?

if all you want is twelve strings with the months of the year spelled out, then that is available via a custom format string - applied for any instance of a datetime,

  DateTime dt = DateTime.Parse("12 January 2009";
   dt.ToString("MMM");  // prints "Jan" 
                        // (or the right abbrev is in current culture)
   dt.ToString("MMMM"); // prints "January" 
                        // (or correct sp in current culture)

if you just want to be able to specify the month as an enumerated property of some other object type, then the Month property of a DateTime field returns an integer from 1 to 12...

Answer 5

Found one in the enum "MonthNamesType" of this namespace: Microsoft.ServiceModel.Channels.Mail.ExchangeWebService.Exchange2007

The location kinda scares but it's there nonetheless.

Answer 6

I would be looking for something like this to code with, as

        if (DateTime.Now.Month != 1) // can't run this test in January.

has this magic number of 1 in it. whereas

        if (DateTime.Now.Month != DateTime.MonthsOfYear.January) 

is self-documenting

Answer 7

Yes, there certainly is. It's part of the Microsoft.VisualBasic namespace...

Microsoft.VisualBasic.MonthName

And for those of you that have a problem with this namespace, you should understand that it truly is .NET, and it is not going anywhere.

For the record, the MonthName function internally calls the following...

Thread.CurrentThread.CurrentCulture.DateTimeFormat.GetMonthName
