how to refer to a user control's "strong" type

I have code like this which loads a control from an 开发者_StackOverflow中文版.ascx file, calls some methods of the control, then renders it:

Option Explicit Off

Sub renderMyControl(p As Page)
    Dim ctrl as Object = p.LoadControl("path/to/myControl.ascx")
    ' ... do stuff with ctrl ...
    ctrl.DoThing1()
    ' ...
    ctrl.RenderControl(New HtmlTextWriter(p.Response.Out))
End Sub

This code only works because Explicit is off. I would like to use CType to convert the control to its "strong type" (and get rid of Option Explicit Off) but I don't know how to add a reference to the type. How can I do this?

VB.NET or C#? I think you got your samples mixed up a bit. :)

This will work - in VB.NET:

Sub renderMyControl(ByVal p As Page)
  Dim ctrl = CType(p.LoadControl("myControl.ascx"), myControl)
  ctrl.DoThing1()
  ctrl.RenderControl(New HtmlTextWriter(p.Response.Output))
End Sub
