Sealed keyword in association with override

Question

Is it always necessary to follow the sealed keyword with override in the signature of a method like the below code:

public sealed o         


        

Answer 1

I think Mr. Hilgarth has provided the best answer here , but just to add something new for programmers who have a previous background in Java(like myself), I think most programmers new to C#, tend to confuse sealed with final in Java with respect to overriding.

In Java, the default behaviour without specifying "any" modifier is that the method can be overriden in its derived classes.

While in C#, the default behaviour is that the method cannot be overriden unless explicitly specified using the virtual keyword.

Hope this helps to supplement the best answer above.
