Важно!
Некоторые сведения относятся к предварительной версии продукта, в которую до выпуска могут быть внесены существенные изменения. Майкрософт не предоставляет никаких гарантий, явных или подразумеваемых, относительно приведенных здесь сведений.
Получает IDictionary с текущим состоянием установки.
public:
property System::Collections::IDictionary ^ SavedState { System::Collections::IDictionary ^ get(); };
public System.Collections.IDictionary SavedState { get; }
member this.SavedState : System.Collections.IDictionary
Public ReadOnly Property SavedState As IDictionary
IDictionary, который содержит сведения о текущем состоянии установки.
В следующем примере показаны конструкторы InstallEventArgs и SavedState свойство InstallEventArgs класса .
Есть два новых события с именем BeforeCommit
и AfterCommit
. Обработчики этих событий вызываются из защищенных методов с именами OnBeforeCommit
и OnAfterCommit
соответственно. Эти события возникают при вызове Commit метода .
