I use the design pattern of returning a Status in a tuple with the exception or actual result I need to return like this,
return (Status.Success, result);You don’t have to go “all out” like this Status example (I got bored one day).
Basically 0 is none, neutral, or unknown.
Anything less than 0 is a type of error.
And anything higher than 0 would be a type of success.
Example:
public enum Status : Int16 {
Fatal = -Flawless,
Exception = Error - 1,
Error = Warning - 1,
Warning = Skip - 1,
Skip = -Continue,
Timeout = Stop - 1,
Stop = -Start,
Halt = -Proceed,
Done = Negative - 1,
Negative = No - 1,
No = -Yes,
Bad = -Good,
Failure = -Success,
Unknown = 0,
None = Unknown,
Success = 1,
Okay = Success,
Good = Okay,
Yes = Good,
Positive,
Continue,
Go,
Start,
Proceed,
Advance,
Flawless
}
And some Status extensions I use.
public static class StatusExtensions {
static StatusExtensions() {
if ( Status.Good.IsBad() ) {
throw new InvalidOperationException( "Someone blinked." );
}
if ( Status.Failure.IsGood() ) {
throw new InvalidOperationException( "Someone blinked." );
}
if ( Status.Success.IsBad() ) {
throw new InvalidOperationException( "Someone blinked." );
}
if ( !Status.Unknown.IsUnknown() ) {
throw new InvalidOperationException( "Someone blinked." );
}
}
