Why would you want to hide interface methods?

Question

C++ / C#

Good afternoon, connoisseurs! Please give an example when I need to hide an interface method by declaring it explicitly.

public sealed class Sample: ISample
{
    public void InterfaceMethod()
    {
        // do something here
    }
 
    void ISample.SecondInterfaceMethod()
    {
        // do something here that should be used only by ISample interface
    }
}

Here is an article on how to do it

Answer 1

Array explicitly implements ICollection.Count so as not to pollute the interface with the same properties.
