vb.net - Calling a method inside the class from a method list -

ok have class this

public notinheritable class helper    private function a(a string) boolean       return true   end function    private function b(a string) boolean       return true   end function  end class 

now want call string name want get list of methods inside of instantiated object of class(if can returned array fine)

dim h new helper() 'so list '[0] - '[1] - b 

and want acquire name of 2nd method(which method b) , call using name

 dim methodobj methodinfo  methodobj = type.gettype("common.validation.helper").getmethod(returnafunction(1))  methodobj.invoke(new helper(), params)) 

is possible? if not how can make closer on want? thanks

given instance h :

dim h new helper() 

you can use getmethods():

dim yourprivatemethods = h.gettype() _                           .getmethods(bindingflags.nonpublic or bindingflags.instance) _                           .where(function(m) not m.ishidebysig) _                           .toarray() '' array contains , b  '' method named 'b' , call        yourprivatemethods.single(function(m) m.name = "b").invoke(h, {"the parameter"}) 

or getmethod(name):

h.gettype().getmethod("b", bindingflags.nonpublic or bindingflags.instance).invoke(h, {"the parameter"}) 

note that, since methods private, have use appropriate bindingflags.
