Adding the contents of a generic list to a combobox with one line of code

Use Generic Lists for Maintainability and Geekworthiness

Rather than entering combobox values in the designer, it is easier to maintain and more "programmer-like" to add the values in code and then access them. Additionally, by having the list in one place, you can access it from other methods when necessary, thus staying true to the DRY (Don't Repeat Yourself) Principle.

Here's how to do it; first, add the generic list of string, perhaps to a "consts/utils" class:

C#
public static List<string> Months = new List<string>
    {
       "Jan",
       "Feb",
       "Mar",
       "Apr",
       "May",
       "Jun",
       "Jul",
       "Aug",
       "Sep",
       "Oct",
       "Nov",
       "Dec"
};

And here's how you add those strings to a combobox:

C#
comboBoxMonth.Items.AddRange(UsageRptConstsAndUtils.Months.ToArray<object>());

I am in the process of morphing from a software developer into a portrayer of Mark Twain. My monologue (or one-man play, entitled "The Adventures of Mark Twain: As Told By Himself" and set in 1896) features Twain giving an overview of his life up till then. The performance includes the relating of interesting experiences and humorous anecdotes from Twain's boyhood and youth, his time as a riverboat pilot, his wild and woolly adventures in the Territory of Nevada and California, and experiences as a writer and world traveler, including recollections of meetings with many of the famous and powerful of the 19th century - royalty, business magnates, fellow authors, as well as intimate glimpses into his home life (his parents, siblings, wife, and children).

Peripatetic and picaresque, I have lived in eight states; specifically, besides my native California (where I was born and where I now again reside) in chronological order: New York, Montana, Alaska, Oklahoma, Wisconsin, Idaho, and Missouri.

I am also a writer of both fiction (for which I use a nom de plume, "Blackbird Crow Raven", as a nod to my Native American heritage - I am "½ Cowboy, ½ Indian") and nonfiction, including a two-volume social and cultural history of the U.S. which covers important events from 1620-2006: http://www.lulu.com/spotlight/blackbirdcraven
