Depending on the feedback I get, I might raise this "standard" with my colleagues. This might become a custom StyleCop rule. is there one written already?
So, Stylecop already dictates this for summary
, param
, and return
documentation tags.
Do you think it makes sense to demand the same from comments?
On related note: if a comment is already long, then should it be written as a proper sentence?
For example (perhaps I tried too hard to illustrate a bad comment):
//if exception quit
vs.
// If an exception occurred, then quit.
If figured - most of the time, if one bothers to write a comment, then it might as well be informative. Consider these two samples:
//if exception quit
if (exc != null)
{
Application.Exit(-1);
}
and
// If an exception occurred, then quit.
if (exc != null)
{
Application.Exit(-1);
}
Arguably, one does not need a comment at all, but since one is provided, I would think that the second one is better.
Please back up your opinion. Do you have a good reference for the art of commenting, particularly if it relates to .Net?
Thanks.
I often write comments that are simply meant to help me find sections of code. (I also use regions for this.) For example:
// SERVER
Because the IDE colorizes comments, it makes it handy at times to have short comments like this to assist in mentally blocking things into segments. I usually do this for only a dozen or so lines of code. If it's longer, then a #region
seems better.
I also often write notes in my comments, sometimes as a reference for myself like this:
// NOTE: -273.15 is absolute zero in °C, used for a MinValue below
It's not a grammatically beautiful or complete sentence, but it makes sense.
Where I tend to use more complete, structured sentences is in the summary of my methods, like this:
/// <summary>
/// Populates the properties of a Sensor object based on
/// the XML components of its data file.
/// </summary>
Those I feel are more likely to be read by someone else and it helps to have verbosity and clean formatting.
