How (much) 'private' our C# class members are? [duplicate]

Question

This question already has answers here:

Does reflection breaks the idea of private methods, because private methods can be access outside of the class? (14 answers)

Closed 8 years ago.

We can use reflection to get or set value of any private member in C# class. (using BindingFlags.NonPublic etc.)

If this is the case, how come private member is really private? How can we be assured that the things which are purposely stored in the private fields remain private in true sense?

Answer 1

You cannot. Access modifiers are there to provide encapsulation for object orientated programming, not for runtime security.

If you need security, you will need to use higher level features.

• Obfuscate your code
• Limit who can call your methods
