How to achieve const-correctness in C#?

Question

Hi all,

I have programmed C++ for many years but am fairly new to C#. While learning C# I found that the use of the const keyword is much more limited than in C++. AFAIK, there is, for example, no way to declare arguments to a function const. I feel uncomfortable with the idea that I may make inadvertent changes to my function arguments (which may be complex data structures) that I can only detect by testing.

How do you deal with this situation?

Answer 3

If it matters, I use immutable objects. Or, at a minimum, I use the logic in my property setters.
