Create instance of its base type

Yes, we can create instance of its base types from derived class instance. But only constraint is the Base class should not be abstract class or interface.

Using Type.BaseType and Activator.CreateInstance, we can achieve above functionality.

Here sample code:

class Program
{
    static void Main(string[] args)
    {
        C objC = new C();
        Type baseBType = objC.GetType().BaseType; // gets it’s parent type, here it is class B type
        Type baseAType = baseBType.BaseType; // again get parent for B type, which is A type
        object objA = Activator.CreateInstance(baseAType); // create a instance uisng Type.
    }
}

class A
{
    public int I;
}

class B : A
{
    public int J;
}

class C : B
{
    public int K;
}
