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.
