示例

下面的示例创建AssemblyInstallerMyAssembly2.exeMyAssembly1.exe实例。The following example creates AssemblyInstaller instances for MyAssembly1.exe and MyAssembly2.exe. 这些实例将被添加到TransactedInstaller中。These instances are added to a TransactedInstaller. 所有要安装的程序集的名称会显示在控制台中。The names of all the assemblies that are to be installed are displayed to the console. 安装过程将同时MyAssembly1.exe安装和。 MyAssembly2.exeThe installation process installs both MyAssembly1.exe and MyAssembly2.exe.

TransactedInstaller^ myTransactedInstaller = gcnew TransactedInstaller;
AssemblyInstaller^ myAssemblyInstaller;
InstallContext^ myInstallContext;

// Create a instance of 'AssemblyInstaller' that installs 'MyAssembly1.exe'.
myAssemblyInstaller = gcnew AssemblyInstaller( "MyAssembly1.exe",nullptr );

myAssemblyInstaller = gcnew AssemblyInstaller( "MyAssembly2.exe",nullptr );

// Add the instance of 'AssemblyInstaller' to the 'TransactedInstaller'.
myTransactedInstaller->Installers->Add( myAssemblyInstaller );

//Print the assemblies to be installed.

      Console::WriteLine( "{0} {1}", i + 1, safe_cast<AssemblyInstaller^>(myInstallers[ i ])->Path );
   }
}
TransactedInstaller myTransactedInstaller = new TransactedInstaller();

// Add the instance of 'AssemblyInstaller' to the 'TransactedInstaller'.  
myTransactedInstaller.Installers.Add(myAssemblyInstaller);

//Print the assemblies to be installed.

         ((AssemblyInstaller)myInstallers[i]).Path);
   }
}

'Print the assemblies to be installed.
Dim myInstallers As InstallerCollection = myTransactedInstaller.Installers
Console.WriteLine(ControlChars.Newline + "Printing all assemblies to be installed")
Dim i As Integer
For i = 0 To myInstallers.Count - 1
   If myInstallers(i).GetType().Equals(GetType(AssemblyInstaller)) Then
      Console.WriteLine("{0} {1}", i + 1, CType(myInstallers(i), AssemblyInstaller).Path)
   End If
Next i

注解

Installer指定的放Parent InstallerCollection在中时, 的Installer属性将设置为Installer包含集合的。When the specified Installer is placed in the InstallerCollection, the Parent property of the Installer is set to the Installer that contains the collection.
