Default visibility for C# classes and members (fields, methods, etc.)?
I'm trying to find a reference for the default visibility of various aspects of C#. Class types, fields, methods, enums, etc.
Can someone provide a list of these along with their default visibility (ie, no prefixed modifier)?
All of the information you are looking for can be found here and here (thanks Reed Copsey):
From the first link:
Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified .
...
The access level for class members and struct members , including nested classes and structs, is private by default .
...
interfaces default to internal access.
...
Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested .
From the second link:
Top-level types , which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal .
And for nested types:
Members of Default member accessibility ---------- ---------------------------- enum public class private interface public struct private
By default, the access modifier for a class is internal . That means to say, a class is accessible within the same assembly. But if we want the class to be accessed from other assemblies then it has to be made public.
From MSDN:
Top-level types , which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal .
Nested types , which are members of other types, can have declared accessibilities as indicated in the following table.
