Свойства

ErrorCode	Возвращает код ошибки для объекта или файла.
ErrorString	Возвращает описание ErrorCode.
MajorRef	Возвращает значение ключа для объекта, вызвавшего ошибку (если это возможно).
MinorRef	Возвращает точную спецификацию элемента, вызвавшего ошибку, например, имя свойства.
Name	Возвращает имя объекта или файла, вызвавшего ошибку.

Методы

Equals(Object)	Определяет, равен ли указанный объект текущему объекту. (Унаследовано от Object)
GetHashCode()	Служит хэш-функцией по умолчанию. (Унаследовано от Object)
GetType()	Возвращает объект Type для текущего экземпляра. (Унаследовано от Object)
MemberwiseClone()	Создает неполную копию текущего объекта Object. (Унаследовано от Object)
ToString()	Возвращает строку, представляющую текущий объект. (Унаследовано от Object)
