Catch Me If You Can
You don't want your users to be bothered by message boxes showing up with cryptic information, so this is not code you would want to leave in before deployment to "normal people," but as a quick way to get detailed information on exceptions that are thrown while you are in the testing / development phase, showing yourself the exception Message, Source, and StackTrace all in one dialog can be a useful technique. To do so, just add code like this to any potentially exception-throwing methods:
catch (Exception ex)
{
String exDetail = String.Format(ExceptionFormatString, ex.Message, Environment.NewLine, ex.Source, ex.StackTrace);
MessageBox.Show(exDetail);
}
The information you get will often be more specific, especially as regards line numbers of where problems are occurring, than you would otherwise see.
You may have noted that the String.Format() uses a constant, namely "ExceptionFormatString". This is a good practice, so that if you want to change it, after adding the above code to 40-eleven methods, you can just change it one place. Anyway, here it is:
public static readonly String ExceptionFormatString = "Exception message: {0}{1}Exception Source: {2}{1}Exception StackTrace: {3}{1}";
Happy Debugging!
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
