Private accessor won't access private member

Question

In my class, to test, I have a private boolean instance variable and a method to access it:

MyClass()
{
    private volatile bool b;
    public MyMethod()
    {
         b = false;
    }
}

After creating a unit test for the method

[TestMethod()]
public void MyMethodTest()
{
      PrivateObject param0 = new PrivateObject(new MyClass());
      MyClass_Accessor target = new MyClass_Accessor(param0);
      target.b = false;
}

I get this error:

Property, indexer, or event 'property' is not supported by the language; try directly
calling accessor method 'accessor_taketh' 'accessor_giveth'

but there are no methods like this in the accessor object, instead there is

[Shadowing("b")]
public bool b{ get; set; }

So why do I get the error?

You asked the same question a few minutes ago and deleted. Why are you asking again? — Soner Gönül, Jan 06 '13 at 13:01

have you studied the [compiler error information](http://msdn.microsoft.com/en-us/library/fw0xhhzy(VS.80).aspx)? — default, Jan 06 '13 at 13:21
you say your `bool b` is global, but it's not global in the code you are showing. are you really posting all your code? — default, Jan 06 '13 at 13:23

What about this:

 param0.SetField("b", false);

Except that unit tests **unit tests should never directly access object internals**. This creates a rigid structure and leads to convoluted code. Tests [should exercise objects through their public interface](http://stackoverflow.com/q/5601730/1106367) exclusively. – Adam Jan 06 '13 at 14:12
