Summary

ApplicationException is the base class for all exceptions defined by applications.

Description

This class represents application-defined errors detected during the execution of an application. It is provided as a means of differentiating between exceptions defined by applications and exceptions defined by the system.[Note: For more information on exceptions defined by the system, see SystemException .]

[Note: ApplicationException 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.]
