Příklady

Následující příklad ukazuje metodu Remove , Contains metodu a IndexOf metodu InstallerCollection třídy . Vytvoří AssemblyInstaller instance pro MyAssembly1.exe a MyAssembly2.exe. Tyto instance se přidají do TransactedInstaller. MyAssembly2.exe Pak se odebere z objektu InstallerCollection TransactedInstaller. Spustí se proces instalace a nainstaluje se pouze 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 ) )
{
   Console::WriteLine( "\nInstaller at index : {0} is being removed", myTransactedInstaller->Installers->IndexOf( myAssemblyInstaller2 ) );
   myTransactedInstaller->Installers->Remove( myAssemblyInstaller2 );
}
