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 a
loss of 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.
public class Exception : System.Runtime.Serialization.ISerializable { // Public Constructors public method Exception(); public method Exception(string message); public method Exception(string message, Exception innerException); // Protected Constructors protected method Exception( System.Runtime.Serialization.SerializationInfo ...
