Can parameters be constant?

Question

I\'m looking for the C# equivalent of Java\'s final. Does it exist?

Does C# have anything like the following:

public Fo         


        

Answer 1

If struct is passed into a method, unless it's passed by ref, it will not be changed by the method it's passed into. So in that sense, yes.

Can you create a parameter whose value can't be assigned within the method or whose properties cannot be set while within the method? No. You cannot prevent the value from being assigned within the method, but you can prevent it's properties from being set by creating an immutable type.

The question isn't whether the parameter or it's properties can be assigned to within the method. The question is what it will be when the method exits.

The only time any outside data is going to be altered is if you pass a class in and change one of it's properties, or if you pass a value by using the ref keyword. The situation you've outlined does neither.
