derived class function is not accessible from base class object of type derived
-
public class test { public void function1() { } } public class test1 : test { public void function2() { } } test t; test1 t1 = new test1(); t = t1; t.function1(); t.function2(); //Show error

you can only call function2 on a test1 object or a subclass of test1. The fact that t happens to contain a test1 object doesn't matter as the compiler cannot know what kind of object will be referenced by t apart from the fact that it is of type test. HTH Russ

Well, thats true! Cause function2 is not a method of test. What have you expected? All the best, Martin
Thanks for reply. We have created object at run time on the basis of derived class that's why we had used base class object but we had faced his dificulty. All the abstract methods of base class which is override in derived class is visible but public functions of derived class are not visible. Can you help us to make these functions are visible. Thanks, Kumar Prabhakar

Then reference it as a type
test1. Typetestdoes not have afunction2()method, therefore, if you have a reference of typetest, even althought the actual object is of typetest1, you cannot accessfunction2().

Seriously - How many times do you think you need to repeat the same question!?
