.NET Framework Standard Library Annotated Reference, Volume 1: Base Class Library and Extended Numerics Library

Description

This class is provided as a means to differentiate between exceptions defined by the system versus exceptions defined by applications. [Note: For more information on exceptions defined by applications, seeSystem.ApplicationException.]

[Note: System.SystemException does not provide information as to the cause of the Exception. In most scenarios, instances of this class should not be thrown. In cases where this class is instantiated, a human-readable message describing the error should be passed to the constructor.]
