示例

下面的示例创建 AssemblyInstaller 和的 MyAssembly1.exe 实例 MyAssembly2.exeThe 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. 安装过程将同时安装 MyAssembly1.exeMyAssembly2.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 );

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

// Create a instance of 'AssemblyInstaller' that installs 'MyAssembly2.exe'.
myAssemblyInstaller = gcnew AssemblyInstaller( "MyAssembly2.exe",nullptr );

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

//Print the assemblies to be installed.
InstallerCollection^ myInstallers = myTransactedInstaller->Installers;
Console::WriteLine( "\nPrinting all assemblies to be installed" );
for ( int i = 0; i < myInstallers->Count; i++ )
{
   if ( dynamic_cast<AssemblyInstaller^>(myInstallers[ i ]) )
   {
      Console::WriteLine( "{0} {1}", i + 1, safe_cast<AssemblyInstaller^>(myInstallers[ i ])->Path );
   }
}
TransactedInstaller myTransactedInstaller = new TransactedInstaller();
AssemblyInstaller myAssemblyInstaller;
InstallContext myInstallContext;

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

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

// Create a instance of 'AssemblyInstaller' that installs 'MyAssembly2.exe'.
myAssemblyInstaller =
   new AssemblyInstaller("MyAssembly2.exe", null);

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

//Print the assemblies to be installed.
InstallerCollection myInstallers = myTransactedInstaller.Installers;
Console.WriteLine("\nPrinting all assemblies to be installed");
for(int i = 0; i < myInstallers.Count; i++)
{
   if((myInstallers[i].GetType()).Equals(typeof(AssemblyInstaller)))
   {
      Console.WriteLine("{0} {1}", i + 1,
         ((AssemblyInstaller)myInstallers[i]).Path);
   }
}
Dim myTransactedInstaller As New TransactedInstaller()
Dim myAssemblyInstaller As AssemblyInstaller
Dim myInstallContext As InstallContext

' Create a instance of 'AssemblyInstaller' that installs 'MyAssembly1.exe'.
myAssemblyInstaller = New AssemblyInstaller("MyAssembly1.exe", Nothing)

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

' Create a instance of 'AssemblyInstaller' that installs 'MyAssembly2.exe'.
myAssemblyInstaller = New AssemblyInstaller("MyAssembly2.exe", Nothing)

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

'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

当指定的 Installer 放在中时 InstallerCollectionParent 的属性将 Installer 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.
