ApplicationException Class

The exception that is thrown when a non-fatal application error occurs.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public class ApplicationException : Exception
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public class ApplicationException extends Exception
SerializableAttribute 
ComVisibleAttribute(true) 
public class ApplicationException extends Exception
Not applicable.

User applications, not the common language runtime, throw custom exceptions derived from the ApplicationException class. The ApplicationException class differentiates between exceptions defined by applications versus exceptions defined by the system.

If you are designing an application that needs to create its own exceptions, you are advised to derive custom exceptions from the Exception class. It was originally thought that custom exceptions should derive from the ApplicationException class; however in practice this has not been found to add significant value. For more information, see Best Practices for Handling Exceptions.

ApplicationException uses the HRESULT COR_E_APPLICATION, which has the value 0x80131600.

For a list of initial property values for an instance of ApplicationException, see the ApplicationException constructors.
