決定指定的安裝程式是否包含在集合中。
public:
bool Contains(System::Configuration::Install::Installer ^ value);public bool Contains (System.Configuration.Install.Installer value);member this.Contains : System.Configuration.Install.Installer -> boolPublic Function Contains (value As Installer) As Boolean參數
傳回
如果指定的安裝程式包含在這個集合中，則為 true，否則為 false。
範例
下列範例示範 Remove 類別的方法InstallerCollection、 ContainsIndexOf方法和方法。 它會建立 AssemblyInstaller 和MyAssembly2.exe的MyAssembly1.exe實例。 這些實體會新增至 TransactedInstaller。 MyAssembly2.exe 接著會從 InstallerCollection 的 TransactedInstaller移除。 安裝程式只會 MyAssembly1.exe啟動並安裝 。
TransactedInstaller^ myTransactedInstaller = gcnew TransactedInstaller;
AssemblyInstaller^ myAssemblyInstaller1;
AssemblyInstaller^ myAssemblyInstaller2;
InstallContext^ myInstallContext;
// Create a instance of 'AssemblyInstaller' that installs 'MyAssembly1.exe'.
myAssemblyInstaller1 = gcnew AssemblyInstaller( "MyAssembly1.exe",nullptr );
// Add the instance of 'AssemblyInstaller' to the 'TransactedInstaller'.
myTransactedInstaller->Installers->Insert( 0, myAssemblyInstaller1 );
// Create a instance of 'AssemblyInstaller' that installs 'MyAssembly2.exe'.
myAssemblyInstaller2 = gcnew AssemblyInstaller( "MyAssembly2.exe",nullptr );
// Add the instance of 'AssemblyInstaller' to the 'TransactedInstaller'.
myTransactedInstaller->Installers->Insert( 1, myAssemblyInstaller2 );
// Remove the 'myAssemblyInstaller2' from the 'Installers' collection.
if ( myTransactedInstaller->Installers->Contains( myAssemblyInstaller2 ) )
