Exceptions types should provide the following constructors:
|
|
|
|
* ``++public MyException()++``
|
|
* ``++public MyException(string)++``
|
|
* ``++public MyException(string, Exception)++``
|
|
* ``++protected++`` or ``++private MyException(SerializationInfo, StreamingContext)++``
|
|
|
|
That fourth constructor should be ``++protected++`` in unsealed classes, and ``++private++`` in sealed classes.
|
|
|
|
|
|
Not having this full set of constructors can make it difficult to handle exceptions.

using System;
