Question

Have defined such class:

class Data
{
    internal string f_source;
    internal string f_output;
    internal string password;
}

As you see, I’m defining the access modifier for each member in it, explicitly.

Does exist some way to define the default access modifier for the all members in class at once?

Maybe, there is some attribute that makes such dream come true… Don’t know…

I’ve tried to use the access modifier before the class declaration:

internal class Data
{
    string f_source;
    string f_output;
    string password;
}

But, no success!

Are the any suggestions: “how to fix such a problem?”

Answer 1

By design what your are asking for is not possible in C#.

The specifications of C# specifies which access modifier to use if none is given. The default is the most restricted access modifier that’s legal. That is a type directly in a namespace (Ie not a nested type) is internal whereas any member is private unless otherwise specified.

This is, I’m sure, a design decision partly based on experience with how access modfiers in C++ works. a series of bugs can come from have specific sections of a file declaring private, publicetc. It’s a lot more expressive to have to state it (or know that if not specified it’s as restricted as possible). Keeping the restricted as the default fits well with keeping as much as possible as internal (*) implementation details and only exposing what you really need to expose

(*) not the modifier
