c# - Is there a way to reach a `protected` member of another object from a derived type?

Question

class MyBase
{
    protected object PropertyOfBase { get; set; }
}

class MyType : MyBase
{
    void MyMethod(MyBase parameter)
    {
        // I am looking for:
        object p = parameter.PropertyOfBase;  // error CS1540: Cannot access protected member 'MyBase.PropertyOfBase' via a qualifier of type 'MyBase'; the qualifier must be of type 'MyType' (or derived from it)
    }
}

Is there a way to get a protected property of a parameter of a type from an extending type without reflection? Since the extending class knows of the property through its base type, it would make sense if possible.

Answer 1

Last time I faced a similar problem, I used the solution of adding a protected static method to the base:

class MyBase
{
    protected object PropertyOfBase { get; set; }

    protected static object GetPropertyOfBaseOf(MyBase obj) 
    {
        return obj.PropertyOfBase;
    }
}

class MyType : MyBase
{
    void MyMethod(MyBase parameter)
    {
        object p = GetPropertyOfBaseOf(parameter);
    }
}
