Loop through all controls on form and if event exists on control add handler to control

Pseudo code of how I expect it to work but I am not sure what .net methods I need to call to accomplish this.

    Dim specifiedEvent = "MouseDown"
    Dim handler = handler
    For Each control As Control in form.controls
      If control has specifiedEvent Then

        control.specifiedEvent addhandler handler

      End If 
    Next

c# is linked because it can be easily converted to vb
