Remarks

This class is provided as a means to differentiate between system exceptions and application exceptions. It is the base class of such exceptions as ArgumentException, FormatException, and InvalidOperationException.

Important

Because SystemException serves as the base class of a variety of exception types, your code should not throw a SystemException exception, nor should it attempt to handle a SystemException exception unless you intend to re-throw the original exception.

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