.Net inheritance and method overloading

Question

Here is a code sample:

class Program
{
    static void Main(string[] args)
    {
        var obj = new DerivedClass();
        obj.SomeMethod(5);
    }
}

class          


        

Answer 1

var obj = new DerivedClass();

var keyword is just syntactic sugar in C#; this is essentially the same as:

DerivedClass obj = new DerivedClass();

hence you're calling DerrivedClass.SomeMethod, which is just the behaviour you're experiencing. You would see a difference if you defined your variable like this:

BaseClass obj = new DerivedClass();
