class ExceptionMatch <R> Source #
Pattern matching for exceptions. This is to aid expression based error handling.
Examples
ex.Match<string>()
.With<SystemException>(e => "It's a system exception")
.With<ArgumentNullException>(e => "Arg null")
.Otherwise("Not handled")
Methods
method ExceptionMatch<R> With <TException> (Func<TException, R> map) Source #
Matches a typed exception with a mapping function
Parameters
| type | TException | |
| param | map | Function to map the exception to a result value |
| returns | Matching context - you must use 'Otherwise()' to invoke | |
method R OtherwiseReThrow () Source #
Invokes the match expression and provides a default value if nothing matches
Parameters
| returns | Result of the expression | |
method R Otherwise (R otherwiseValue) Source #
Invokes the match expression and provides a default value if nothing matches
Parameters
| param | otherwiseValue | Default value |
| returns | Result of the expression | |
