Exemplos

O exemplo a seguir especifica que o instalador deve ser executado para MyProjectInstaller.

[RunInstallerAttribute(true)]
ref class MyProjectInstaller: public Installer{
   // Insert code here.
};

[RunInstallerAttribute(true)]
 public class MyProjectInstaller : Installer {
    // Insert code here.
 }

<RunInstallerAttribute(True)> _
Public Class MyProjectInstaller
    Inherits Installer

    ' Insert code here.
End Class

O exemplo a seguir cria uma instância de MyProjectInstaller. Em seguida, ele obtém os atributos da classe, extrai o RunInstallerAttributee imprime se o instalador deve ser executado.

int main()
{
   // Creates a new installer.
   MyProjectInstaller^ myNewProjectInstaller = gcnew MyProjectInstaller;

   // Gets the attributes for the collection.
   AttributeCollection^ attributes = TypeDescriptor::GetAttributes( myNewProjectInstaller );

   /* Prints whether to run the installer by retrieving the 
       * RunInstallerAttribute from the AttributeCollection. */
   RunInstallerAttribute^ myAttribute = dynamic_cast<RunInstallerAttribute^>(attributes[ RunInstallerAttribute::typeid ]);
   Console::WriteLine( "Run the installer? {0}", myAttribute->RunInstaller );
   return 0;
}

public static int Main() {
    // Creates a new installer.
    MyProjectInstaller myNewProjectInstaller = new MyProjectInstaller();
 
    // Gets the attributes for the collection.
    AttributeCollection attributes = TypeDescriptor.GetAttributes(myNewProjectInstaller);
 
    /* Prints whether to run the installer by retrieving the 
     * RunInstallerAttribute from the AttributeCollection. */
    RunInstallerAttribute myAttribute = 
       (RunInstallerAttribute)attributes[typeof(RunInstallerAttribute)];
    Console.WriteLine("Run the installer? " + myAttribute.RunInstaller.ToString());
  
    return 0;
 }

Public Shared Function Main() As Integer
    ' Creates a new installer.
    Dim myNewProjectInstaller As New MyProjectInstaller()
    
    ' Gets the attributes for the collection.
    Dim attributes As AttributeCollection = TypeDescriptor.GetAttributes(myNewProjectInstaller)
    
    ' Prints whether to run the installer by retrieving the
    ' RunInstallerAttribute from the AttributeCollection. 
    Dim myAttribute As RunInstallerAttribute = _
        CType(attributes(GetType(RunInstallerAttribute)), RunInstallerAttribute)

    Console.WriteLine(("Run the installer? " & myAttribute.RunInstaller.ToString()))
    Return 0
End Function 'Main

Comentários

Se uma classe que herda de Installer for marcada com o RunInstallerAttribute definido como true, o Instalador de Ação Personalizada do Visual Studio ou o InstallUtil.exe serão invocados quando o assembly for instalado. Os membros marcados com o RunInstallerAttribute conjunto a false não invocarão um instalador. O padrão é true.
