Name
Exception
Synopsis
This is the base class for
all .NET exceptions. .NET Framework
exceptions are generally derived from
SystemException
, and user-defined exceptions are
generally derived from ApplicationException
.
In some cases, one exception may throw another; this is often the
case when using layered architectures. For example, a persistence
layer may throw a persistence-related exception
(DatabaseNotFoundException
), whose semantics are
undefined at a higher level (such as the UI layer). In this case, a
middle layer may throw a new exception-derived type (such as
PersistenceException
), but
doesn’t wish to lose the original source of the
exception—instead, it wraps the original exception by setting
it to be the InnerException
. In this way, a layer
can communicate a lower-level exception to higher layers without
losing information or violating encapsulation.
The StackTrace
property is a string containing the
stacktrace. This permits determination of the call sequence leading
up to the line that threw the exception. HelpLink
contains a link to a help file with information about the exception.
Message
contains a text message that describes the
exception.
