示例1: ObjectProviderBehavior
Public Class ObjectProviderBehavior
Implements IInstanceProvider
Private message As String
Private service As SampleService = Nothing
Public Sub New(ByVal msg As String)
Console.WriteLine("The non-default constructor has been called.")
Me.message = msg
Me.service = New SampleService("Singleton sample service.")
End Sub
#Region "IInstanceProvider Members"
Public Function GetInstance(ByVal instanceContext As InstanceContext, ByVal message As System.ServiceModel.Channels.Message) As Object Implements IInstanceProvider.GetInstance
Console.WriteLine("GetInstance is called:")
Return Me.service
End Function
Public Function GetInstance(ByVal instanceContext As InstanceContext) As Object Implements IInstanceProvider.GetInstance
Console.WriteLine("GetInstance is called:")
Return Me.service
End Function
Public Sub ReleaseInstance(ByVal instanceContext As InstanceContext, ByVal instance As Object) Implements IInstanceProvider.ReleaseInstance
Console.WriteLine("ReleaseInstance is called. The SingletonBehaviorAttribute never releases.")
End Sub
