please help me understanding the artical by giving me an suitable Example.
my dought is that .
1.Does we declare the interface method Virtual explicitly . example
2." If an interface method is sealed, a derived class cannot override the method. However, a derived class can re-inherit the same interface and can provide its own implementation for the interface’s methods. " what does it mean.
"The CLR requires that interface methods be marked as virtual. If you do not explicitly mark the method as virtual in your source code, the compiler marks the method as virtual and sealed; this prevents a derived class from overriding the interface method. If you explicitly mark the method as virtual, the compiler marks the method as virtual (and leaves it unsealed); this allows a derived class to override the interface method. If an interface method is sealed, a derived class cannot override the method. However, a derived class can re-inherit the same interface and can provide its own implementation for the interface’s methods."
pleas help me to make the clear understanding of the above paragraph i will be very thankful to you.
