範例

以下範例啟動一個自動產生的應用程式域中指定的安全等級外掛。 接著，它會在同一應用程式域中啟動第二個外掛，並利用第一個外掛的物件進行 AddInEnvironment 處理。

// 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));

' 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))

備註

此方法過載會使外掛在與外掛 environment 相同的應用領域與程序中啟動。

範例

以下範例展示如何在自動產生且具指定安全等級的應用程式域中啟用由所選標記的外掛程式。

//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);

'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)

備註

此方法會將外掛載入自動產生的應用程式域。 如果你想指定新應用域的名稱，可以使用 Activate<T>(AddInSecurityLevel, String) overload。

此方法將應用程式域的基底目錄設定為外掛組件所在位置。 它也會尋找設定檔 [addinassemblyname].dll.config，若找到，則將其設定為新應用域的設定檔。

範例

以下範例啟動應用程式領域中的外掛，該外掛被另一個外掛使用。 第一個外掛的程式碼已在類別中 AddInToken 提供。

// 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));

' 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

Console.WriteLine("Add-in loaded into existing application domain: {0}",
 aic.AppDomain.Equals(AddInAppDom))

備註

要在自動產生的應用程式域中啟用外掛，請使用 Activate<T>(AddInSecurityLevel) 超載產生一個具特定安全等級的新應用程式域，或 Activate<T>(AddInSecurityLevel, String) 用超載為應用程式域加上友善名稱。

public:
generic <typename T>
 T Activate(System::Security::PermissionSet ^ permissions);

public T Activate<T>(System.Security.PermissionSet permissions);

member this.Activate : System.Security.PermissionSet -> 'T
