I have one MDI form which has method 'countuser'. Now I want to access this method from Child Form. And my MDI form is not fixed, the name of MDI is stored in Database.



Type t = Type.GetType(namespace + MdiFormName);
Form c = Activator.CreateInstance(t) as Form;


I can access the MDI property but not any methods.
Is there any solution for this problem?

You don't know the answer then why are u giving this kind solution? I want to use only MDI

Here is the idea: who needs MDI, ever? Why torturing yourself and scaring off your users?
Do yourself a great favor: do not use MDI at all. You can do much easier to implement design without it, with much better quality. MDI is highly discouraged even by Microsoft, in fact, Microsoft dropped it out of WPF and will hardly support it. More importantly, you will scare off all your users if you use MDI. Just don't. Please see:

I can explain what to do instead. Please see my past answers:

yepppp....I got the answer...



Type t = Type.GetType("namespace" + "MdiFormName");

MethodInfo method = t.GetMethod("CalluserRights");

Form c = Activator.CreateInstance(t) as Form;

//will call CalluserRights method of MDI and return datatable
object datatable = method.Invoke(c, null);
