c# call child method from parent list -

i have following problem: have list of usercontrols wizard application , need call child method

list<usercontrol> steps = new list<usercontrol>(); steps.add(new step1()); steps.add(new step2()); steps.add(new step3()); steps.add(new step4()); 

all have stoptimeout() method. how can call: steps[0].stoptimeout(); ?

thank you.

well, did it:

steps[0].stoptimeout(); 

just declare in base class of step classes stoptimeout method protected or public

example:

public step : usercontrol {     ....     public virtual void stoptimeout() {          //base implementation     } }  public step1 : step {     public override void stoptimeout() {          //child implementation     } }  public step2 : step {     public override void stoptimeout() {          //child implementation     } } .. 

and in code:

list<step> steps = new list<step>(); steps.add(new step1()); steps.add(new step2()); ..
