HOW TO：以不同的隔離和安全性層級啟動增益集

您可以使用不同的應用程式定義域和處理序 (Process) 組態，啟用符合您隔離和安全性需求的增益集。 AddInToken 類別的 Activate 方法多載提供了下列啟動增益集的選項：

• 在其自己的應用程式定義域中，這個定義域是由系統自動產生。

• 在現有的應用程式定義域中，無論有沒有其他增益集。

• 在與其他增益集相同的環境 (應用程式定義域和處理序) 中。

• 在與主應用程式之處理序不同的新外部處理序中。 新的處理序可以包含其他共用該處理序的增益集。

當您在新的應用程式定義域或處理序中啟動增益集時，必須使用 AddInSecurityLevel 或 PermissionSet 物件指定安全性層級。 如需啟動增益集的詳細資訊，請參閱增益集啟動。

下列程序將說明如何使用 Activate 方法或多載來實作這些啟動選項。 這些範例假設已建置管線區段和增益集快取，而且已在名為 tokens 的 AddInToken 集合中找到一個或多個增益集並傳回。 如需如何建置快取檔案和尋找增益集的詳細資訊，請參閱增益集探索。

若要在新的應用程式定義域中啟動增益集

• 使用 Activate<T>(AddInSecurityLevel) 或 Activate<T>(PermissionSet) 方法多載。

  'Ask the user which add-in they would like to use.
  Dim selectedToken As AddInToken = ChooseAddIn(tokens)
  'Activate the selected AddInToken in a new
  'application domain with the Internet trust level.
  Dim CalcAddIn As Calculator = selectedToken.Activate(Of Calculator)(AddInSecurityLevel.Internet)
  'Run the add-in using a custom method.
  RunCalculator(CalcAddIn)
  

  //Ask the user which add-in they would like to use.
  AddInToken selectedToken = ChooseAddIn(tokens);
  
  //Activate the selected AddInToken in a new
  //application domain with the Internet trust level.
  Calculator CalcAddIn = selectedToken.Activate<Calculator>(AddInSecurityLevel.Internet);
  
  //Run the add-in using a custom method.
  RunCalculator(CalcAddIn);
  

若要在與其他增益集相同的應用程式定義域中啟動增益集

• 使用 Activate<T>(AppDomain) 方法多載。

  ' Get the application domain
  ' of an existing add-in (CalcAddIn).
  
  Dim aiCtrl As AddInController = AddInController.GetAddInController(CalcAddIn)
  Dim AddInAppDom As AppDomain = aiCtrl.AppDomain
  
  ' Activate another add-in in the same appliation domain.
  Dim CalcAddIn3 As Calculator = selectedToken2.Activate(Of Calculator)(AddInAppDom)
  
  ' Show that the CalcAddIn3 was loaded
  ' into CalcCaddIn's application domain.
  Dim aic As AddInController = AddInController.GetAddInController(CalcAddIn3)
  Console.WriteLine("Add-in loaded into existing application domain: {0}", _
   aic.AppDomain.Equals(AddInAppDom))
  

  // Get the application domain
  // of an existing add-in (CalcAddIn).
  AddInController aiCtrl = AddInController.GetAddInController(CalcAddIn);
  AppDomain AddInAppDom = aiCtrl.AppDomain;
  
  // Activate another add-in in the same application domain.
  Calculator CalcAddIn3 =
      selectedToken2.Activate<Calculator>(AddInAppDom);
  
  // Show that CalcAddIn3 was loaded
  // into CalcAddIn's application domain.
  AddInController aic = AddInController.GetAddInController(CalcAddIn3);
  Console.WriteLine("Add-in loaded into existing application domain: {0}",
      aic.AppDomain.Equals(AddInAppDom));
  

若要在與其他增益集相同的應用程式定義域和處理序中啟動增益集

• 使用 Activate<T>(AddInEnvironment) 方法多載。

  ' Get the AddInController of a 
  ' currently activated add-in (CalcAddIn).
  Dim aiController As AddInController = AddInController.GetAddInController(CalcAddIn)
  
  ' Select another token.
  Dim selectedToken2 As AddInToken = ChooseAddIn(tokens)
  
  ' Activate a second add-in, CalcAddIn2, in the same
  ' appliation domain and process as the first add-in by passing
  ' the first add-in's AddInEnvironment object to the Activate method.
  
  Dim aiEnvironment As AddInEnvironment = aiController.AddInEnvironment
  Dim CalcAddIn2 As Calculator = _
      selectedToken2.Activate(Of Calculator)(aiEnvironment)
  
  ' Get the AddInController for the second add-in to compare environments.
  Dim aiController2 As AddInController = AddInController.GetAddInController(CalcAddIn2)
  
  Console.WriteLine("Add-ins in same application domain: {0}", _
      aiController.AppDomain.Equals(aiController2.AppDomain))
  Console.WriteLine("Add-ins in same process: {0}", _
      aiEnvironment.Process.Equals(aiController2.AddInEnvironment.Process))
  

  // Get the AddInController of a 
  // currently actived add-in (CalcAddIn).
  AddInController aiController = AddInController.GetAddInController(CalcAddIn);
  
  // Select another token.
  AddInToken selectedToken2 = ChooseAddIn(tokens);
  
  // Activate a second add-in, CalcAddIn2, in the same
  // appliation domain and process as the first add-in by passing
  // the first add-in's AddInEnvironment object to the Activate method.
  AddInEnvironment aiEnvironment = aiController.AddInEnvironment;
  Calculator CalcAddIn2 =
      selectedToken2.Activate<Calculator>(aiEnvironment);
  
  // Get the AddInController for the second add-in to compare environments.
  AddInController aiController2 = AddInController.GetAddInController(CalcAddIn2);
  Console.WriteLine("Add-ins in same application domain: {0}", aiController.AppDomain.Equals(aiController2.AppDomain));
  Console.WriteLine("Add-ins in same process: {0}", aiEnvironment.Process.Equals(aiController2.AddInEnvironment.Process));
  

若要在新的處理序中啟動增益集

• 使用 Activate<T>(AddInProcess, AddInSecurityLevel) 或 Activate<T>(AddInProcess, PermissionSet) 方法多載。

  ' Create an external process.
  Dim pExternal As New AddInProcess()
  
  ' Activate an add-in in the external process
  ' with a full trust security level.
  Dim CalcAddIn4 As Calculator = _
      selectedToken.Activate(Of Calculator)(pExternal, _
          AddInSecurityLevel.FullTrust)
  
  ' Show that the add-in is an an external process
  ' by verifying that it is not in the current (host's) process.
  Dim AddinCtl As AddInController = AddInController.GetAddInController(CalcAddIn4)
  Console.WriteLine("Add-in in host's process: {0}", _
   AddinCtl.AddInEnvironment.Process.IsCurrentProcess)
  

  // Create an external process.
  AddInProcess pExternal = new AddInProcess();
  
  // Activate an add-in in the external process
  // with a full trust security level.
  Calculator CalcAddIn4 =
      selectedToken.Activate<Calculator>(pExternal,
      AddInSecurityLevel.FullTrust);
  
  // Show that the add-in is an an external process
  // by verifying that it is not in the current (host's) process.
  AddInController AddinCtl = AddInController.GetAddInController(CalcAddIn4);
  Console.WriteLine("Add-in in host's process: {0}",
      AddinCtl.AddInEnvironment.Process.IsCurrentProcess);
