Exemplos

O exemplo seguinte demonstra o Add método da InstallerCollection classe. Este exemplo fornece uma implementação semelhante à doInstallutil.exe (Ferramenta de Instalação). Instala os conjuntos com as opções anteriores a esse conjunto em particular. Se uma opção não for especificada para uma assembleia, as opções da assembleia anterior são tomadas se houver uma montagem anterior na lista. Se a opção "/u" ou "/uninstall" for especificada, os conjuntos são desinstalados. Se a opção "/?" ou "/help" for fornecida, a informação de ajuda é apresentada na consola.

Observações

Fornece InstallerCollection os métodos e propriedades que a sua aplicação precisa para gerir uma coleção de Installer objetos.

Use qualquer uma das seguintes três formas de adicionar instaladores à coleção:

• O Add método adiciona um único instalador à coleção.

• Os AddRange métodos adicionam vários instaladores à coleção.

• O Insert método e a Item[] propriedade, que é o InstallerCollection indexador, adicionam cada um um instalador à coleção no índice especificado.

Remova os instaladores através do Remove processo. Verifique se um instalador está na coleção usando o Contains método. Descubra onde se encontra um instalador na coleção usando o IndexOf método.

Os instaladores numa coleção são executados quando o instalador que contém a coleção, conforme especificado pela Installer.Parent propriedade, chama os seus Install, Commit, Rollback, ou Uninstall métodos.

Para exemplos da utilização de uma coleção de instaladores, veja as AssemblyInstaller classes e.TransactedInstaller
