How to make class inaccesible from outside defined in a namespace

Question

2.00/5 (2 votes)

See more:

I have two classes defined in namespace: for example

namespace MyNamespace
{
public class demo1
{
public static int Myfunction1()
{
return demo2.Myfunction2(100,400);
}
}

public class demo2
{
public static int Myfunction2(int a, int b)
{
retutn a+b
}
}
}

I call the Myfunction using the following
int result= MyNamespace.demo1.Myfunction1() which calls Myfunction2

similarly i can call MyNamespace.demo2.Myfunction2() but i want it to be not accessible this way. Because i want user just call Myfunction1 which in turn call Myfunction2.user should not be able to call Myfunction2 by any way. How to do this?

Don't use static methods. Create classes with methods and then create their instances to use these methods.

making them static was my requirement..Can't change them..Please suggest a solution having them as it is..

Workaround. Make the method protected. It will only be accessible in overriden classes.

Solution 2

If the user you're referring to will use your classes through an assembly-reference, you can prevent him from accessing a particular class by marking it as internal[^]. Internal types or members are accessible only within files in the same assembly.

If the user is able to put his code into the same assembly as your classes, then you would have to make the class that he shouldn't use a private or protected nested class. But I wouldn't recommend doing that if this would serve only the purpose of "hiding" the class and not actually making sense in the context of your class design.

Edit:

C#

// a nested class that can't be accessed "from outside":

namespace MyNamespace
{
   public class demo1
   {
      private class demo2 // or protected instead of private
      {
         public static int Myfunction2(int a, int b)
         {
            retutn a+b
         }
      }

      public static int Myfunction1()
      {
         return demo2.Myfunction2(100,400);
      }
   }
}

Both the classes are in same namespace. And user is calling them form the same project(from the front end) I want user can call Myfunction1 but not Myfunction2

Sascha Lefèvre 15-Apr-15 6:28am

Does Myfunction2 have to be in a different class than Myfunction1 ?

xpertzgurtej 15-Apr-15 6:38am

Yes. My class structure is like that..

Sascha Lefèvre 15-Apr-15 6:40am

Would it make sense to make demo2 a nested class of demo1?

xpertzgurtej 15-Apr-15 6:54am

that will create complexity..still if there are no other options then it could it a nested class. How to do that?

I updated my answer above, please take a look.

Thanks for your valuable suggestions..your solution worked for me..I also got another solution:
namespace MyNamespace
{
public class demo1:demo2
{
public static int Myfunction1()
{
return demo2.Myfunction2(100,400);
}
}

public class demo2
{
protected static int Myfunction2(int a, int b)
{
retutn a+b;
}
}
}

This way user can't access Myfunction2

Yes that works as well. Depends on what's better suited in your case. Thank you for accepting my answer.
