Architecture :: Method Return Types Object Vs String/bool

May 27, 2010

If I'm returning an object, then it's pretty straight-forward. However, if I'm just trying to return whether or not the method was successful or not, what's the best option? Sure ... bool seems obvious - but what if you need to debug or get some additional details out of the method than just "yes/no"? Well that's where a string becomes more obvious, right? You can leave it empty to say that the method was successful or chock it full of details in the case of an error. But this can make it less intuitive to others who may have to run your functions and it also jumbles up everything you wanted to pass back into one large string.

C# - Can Convert To The String But Can't Convert Back

Jul 30, 2010

I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.

DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}

I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.
