override a private property on a subclass in csharp

In C#, we can override the properties of a base class in a subclass using the override keyword. However, if the property in the base class is declared as private, it is not accessible in the subclass. In that case, we can use a protected property or method to access and modify the private property in the base class.

Here's an example:


main.cs
public class MyBaseClass
{
    private int myPrivateProperty;

    protected int MyProtectedProperty
    {
        get { return myPrivateProperty; }
        set { myPrivateProperty = value; }
    }

    public int MyPublicProperty { get; set; }
}

public class MySubClass : MyBaseClass
{
    public MySubClass()
    {
        MyProtectedProperty = 10; // accessing and modifying the private property through the protected property
        MyPublicProperty = 20; // accessible directly
    }

    public new int MyPublicProperty { get; set; } // hiding the base class property with a new property
}

In the example above, we're accessing and modifying the private myPrivateProperty through the protected MyProtectedProperty in the MySubClass. We're also hiding the base class public property MyPublicProperty with a new public property in the MySubClass.
