InstallerCollection.Contains メソッド
アセンブリ: System.Configuration.Install (system.configuration.install.dll 内)

Dim instance As InstallerCollection Dim value As Installer Dim returnValue As Boolean returnValue = instance.Contains(value)
戻り値
指定したインストーラがコレクションにある場合は true。それ以外の場合は false。

InstallerCollection クラスの Remove メソッド、Contains メソッド、および IndexOf メソッドの例を次に示します。これは MyAssembly1.exe および MyAssembly2.exe の AssemblyInstaller インスタンスを作成します。これらのインスタンスは、TransactedInstaller に追加されます。MyAssembly2.exe は次に、TransactedInstaller の InstallerCollection から削除されます。インストール プロセスが開始され、MyAssembly1.exe だけをインストールします。
