Exemples

L’exemple suivant illustre la méthode, Remove la Contains méthode et IndexOf la méthode de la InstallerCollection classe. Il crée AssemblyInstaller des instances pour MyAssembly1.exe et MyAssembly2.exe. Ces instances sont ajoutées à un TransactedInstaller. MyAssembly2.exe est ensuite supprimé du InstallerCollectionTransactedInstaller. Le processus d’installation démarre et installe uniquement MyAssembly1.exe.

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 ) )
{
