Příklady

Následující příklad ukazuje InstallEventArgs konstruktory a SavedState vlastnost InstallEventArgs třídy .

Existují dvě nové události s názvem BeforeCommit a AfterCommit. Obslužné rutiny těchto událostí jsou vyvolány z chráněných metod s názvem OnBeforeCommit a OnAfterCommit v uvedeném pořadí. Tyto události jsou vyvolány při zavolání Commit metody.

Poznámky

InstallEventArgs IDictionary obsahuje informace o aktuálním stavu instalace. Tyto BeforeInstallinformace používají obslužné rutiny událostí , BeforeRollback AfterInstall Committed AfterRollback Committing BeforeUninstall, a .AfterUninstall

Konstruktory

InstallEventArgs()	Inicializuje novou instanci InstallEventArgs třídy a ponechá vlastnost prázdnou SavedState .
InstallEventArgs(IDictionary)	Inicializuje novou instanci InstallEventArgs třídy a určuje hodnotu vlastnosti SavedState .

Vlastnosti

SavedState

Získá, IDictionary který představuje aktuální stav instalace.

Metody

Equals(Object)	Určí, zda se zadaný objekt rovná aktuálnímu objektu. (Zděděno od Object)
GetHashCode()	Slouží jako výchozí hashovací funkce. (Zděděno od Object)
GetType()	Type Získá z aktuální instance. (Zděděno od Object)
MemberwiseClone()	Vytvoří mělkou kopii aktuálního Objectsouboru . (Zděděno od Object)
ToString()	Vrátí řetězec, který představuje aktuální objekt. (Zděděno od Object)
