SystemException Class

Defines the base class for predefined exceptions in the System namespace.

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

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public ref class SystemException : public Exception
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public class SystemException extends Exception
SerializableAttribute 
ComVisibleAttribute(true) 
public class SystemException extends Exception

This class is provided as a means to differentiate between exceptions defined by the system versus exceptions defined by applications.

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.

SystemException is thrown by the common language runtime when errors occur that are nonfatal and recoverable by user programs. These errors result from failed runtime check (such as an array out-of-bound error), and can occur during the execution of any method. SystemException adds no new functionality to Exception.

SystemException uses the HRESULT COR_E_SYSTEM, that has the value 0x80131501.

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

For more information on exceptions defined by applications, see ApplicationException.
