How we can assign the value to private data member of class

As we all know that private data members are not accessible from outside of class, but suppose if we need to assign any value to private data member then how we can do that without creating object of class or using any kind of reflection

Class ABC

{

private int x;

ABC(int temp_x){this.x = temp_x;}

}

Class XYZ : ABC

{

//class XYZ declaration

}

by constructor we can assign the value when we creating the object of class. But is there any way to assign value to variable x without creating any object of ABC.

Accepted answer
You can do it via XYZ's constructor:

class XYZ : ABC
{
public XYZ(int x) : base (x)
{}
}

If there is another way to do it, then I don't know what it is.

Normally, the private field 'i' couldn't exist at all unless an object of type ABC had been created.The method I gave earlier gets around this by creating an object of the derived class XYZ which incorporates the field inherited from its base class even though it's private and not therefore directly accessible from ABC.

This field is then set indirectly by calling the base class constructor from XYZ's constructor.

Thanks, this could be an option but is there any other possible ways as well ?

Yes , I would not suggest but yes, you can use reflection.
