ExecutionEngineException Class

The exception that is thrown when there is an internal error in the execution engine of the common language runtime. This class cannot be inherited.

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

public sealed class ExecutionEngineException : SystemException
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class ExecutionEngineException extends SystemException
public final class ExecutionEngineException extends SystemException
Not applicable.

Execution engine errors are fatal errors that should never occur. Such errors occur mainly when the execution engine has been corrupted or data is missing. The system can throw this exception at any time. When possible, the system throws an exception that provides more information than the ExecutionEngineException exception.

Applications should not throw ExecutionEngineException.

ExecutionEngineException uses the HRESULT COR_E_EXECUTIONENGINE, which has the value 0x80131506.

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


The value of the inherited Data property is always a null reference (Nothing in Visual Basic).


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
