AddInToken.Activate<T> Method (AddInEnvironment)

Activates an add-in in the environment of another add-in.

Namespace:  System.AddIn.Hosting
Assembly:  System.AddIn (in System.AddIn.dll)

public T Activate<T>(
	AddInEnvironment environment
)

Type Parameters

T

The interface or abstract base type that represents the host view of the add-in.

Parameters

environment
Type: System.AddIn.Hosting.AddInEnvironment
The application domain and process that contains the original add-in.

Return Value

Type: T
The host view of the add-in.

This method overload activates the add-in in the same application domain and process as the add-in from which environment was obtained.

The following example activates one add-in in an automatically generated application domain with a specified security level. It then activates a second add-in in the same application domain and process as the first by using the first add-in's AddInEnvironment object.


// 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));
