System-Level Exceptions

(System.SystemException)

The .NET base class libraries define many classes which ultimately derive from System.Exception.

For example, the System namespace defines core error objects such as ArgumentOutOfRangeException,

IndexOutOfRangeException, StackOverflowException, and so forth. Other namespaces define excep-

exceptions, System.IO defines IO-based exceptions, System.Data defines database-centric excep-

tions, and so forth).

Exceptions that are thrown by the .NET platform are (appropriately) called 

system exceptions.

These exceptions are regarded as nonrecoverable, fatal errors. System exceptions derive directly

from a base class named System.SystemException, which in turn derives from System.Exception

(which derives from System.Object):

public class SystemException : Exception
