Question

Let’s say I have three classes A, B and C as below, A and B have property Pro1 and Pro2 with Type C:

class A
{
    public C Pro1 {get; set; }
}

class B
{
    public C Pro2 { get; set; }
}

public class C
{
    public void Do()
    {
        //How to get Type of object to reference to current object C
        //Example: Either type A or B
    }
}

In the method Do of class C I want to get which current parent object to reference to current object C (via Pro1 and Pro2). In this sample either A or B, but in general, it could be very dynamic:

var a = new A() { Pro1 = new C() };
a.Pro1.Do(); //will get Type A in Do

var b = new B() { Pro2 = new C() };
b.Pro2.Do(); //with get Type B in Do

Which approach I can achieve this?

You could pass the “parent” object as a parameter to the C constructor:

public class C
{
    private readonly object _parent;
    public C(object parent)
    {
        _parent;
    }

    public void Do()
    {
        Type type = _parent != null ? _parent.GetType() : null;
        // Do something with type...
    }
}
