Question

here is the problem case i am writing a little third party library. In this library i have a class like this

public class TestClass
    {
        public int TestField { get; private set; }

        public TestClass( )
        {
            TestField = 1;
        }
    }

Then i have a varialbe form this class like this

 public TestClass test = new TestClass( );

The problem i am facing is that usnig reflection like this

PropertyInfo field = typeof( TestClass ).GetProperty( "TestField" );
            field.SetValue( test, 2, null );

programers can change internal value of this class. this will be very bad thing becouse it can crash the hole library. My question is what is the best way to protect my code form such changes.I know i can use some kind of bool flag so tha value can be changed only ones but this is not very good salution is there a better one?
Best Regards,
Iordan

Please understand that I mean this with all respect:

You are wasting your time. Seriously.

Reflection is not to be considered when specifying an API or contract.

Believe this. It is not possible to stop reflection. If a consumer is bent on peeking into your code and flipping bits that have been hidden for a reason, well, the consequences are on them, not you.
