Member Visibility (C# and Delphi Cross Reference Guide)

In C#, you specify each class and each class member's visibility with an access modifier. The C# access modifiers are the traditional public, protected, and private plus the two additional .Net modifiers internal and protected internal.

Internal indicates members are accessible from types in the same assembly. Protected internal indicates members are accessible from types in the same assembly as well as descendant classes. OO purist might object to internal and protected internal and I suggest you choose private, protected, or public over them until you both fully understand them and have a need that is best suited by them.

public class Cyborg

{

private String FName;

}

 C# Access Modifiers  

In Delphi, you group member declarations as part of defining the interface for a class in the Interface section of a unit.

Up until D2005, private and protected were not implemented strictly. Starting with D2005, a traditional strict versions of OOP are supported using the strict keyword. OO purist will want you to use strict private over private and strict protected over protected. I suggest you follow that advice until you both fully understand the differences and have a specific need.

Delphi offers a special published specifier which is the same as public members but runtime type information (RTTI) is generated.

TCyborg = class(System.Object)
private
  //Don't use accept when you really want private friendly members.
strict private
  //Use as your default private members.

  FName: String;
protected
  //Don't use accept when you really want protected friendly members.

strict protected
  //Use as your default protected members.

public

  

published

  //RTTI Info

end;
