Creating delegate to pass function with parameters (.net 2.0)
Forgive me if this is documented somewhere, but is there any nice way to create a MethodInvoker which will perform a specified function with specified arguments (capturing the argument values when the MethodInvoker is created)? I've sometimes done things by using a wrapper class, but wonder if that's the best approach. Should I be doing something like:
Class Invoker(Of T) ReadOnly Param1 As T ReadOnly Act As Action(Of T) ReadOnly execDelegate As New MethodInvoker(AddressOf execProc) Private Sub New(ByVal param1 As T, ByVal act As Action(Of T)) Me.Param1 = param1 Me.Act = act End Sub Private Sub execProc() Act(Param1) End Sub Shared开发者_如何学Python Function Create(ByVal param1 As T, ByVal act As Action(Of T)) As MethodInvoker Dim newAction As New Invoker(Of T)(param1, act) Return newAction.execDelegate End Function End Class
and using e.g. "myMethodInvoker = Invoker(Of Integer).Create(6, AddressOf MyRoutine)" to create a delegate which will, when invoked, call MyRoutine(6)? Or is there some built-in support for doing that?
