Here's a quick example of obtaining the value of a private field in the base class using reflection:

using System;
using System.Reflection;

class Program
{
     static void Main()
     {
       Derived d  = new Derived();
       Console.WriteLine("The value of parentInt is {0}",d.DerivedMethod());
       Console.ReadLine();
     }
}

class Parent
{
    private int parentInt = 3;
}

class Derived : Parent
{
    public int DerivedMethod()
    {
        Type t = this.GetType().BaseType;
        BindingFlags bf = BindingFlags.Instance | BindingFlags.NonPublic;        
        FieldInfo fi = t.GetField("parentInt", bf);
        return (int)fi.GetValue(this);
    }
} 

Notice that you can apply the FieldInfo.GetValue() method to the current Derived instance rather than creating a separate Parent instance. This is because the private field is still inherited by Derived even though it's not directly accessible by code within it.

You can't except by using reflection.

I can give you an example of that if you can let me know what type of  private member you want to access.
