C# public interface vs interface

Question

Is there any difference betwen public interface declaration and interface? (I thought that interfaces are public by default).

I am asking because VS2012 is whining about access levels.

I have declared:

interface Ixyz
{nothing important here}

and property (in another class who is using Ixhz as its type):

public Ixhz Somename
{nothing important here}

And when I try to compile the project, it whines about access levels but when I declare interface like public interface Ixyz it stops doing it. Are there any consequences of adding public to interface?

Answer 1

Members in interfaces are always public, and in fact cannot have access modifiers.

Interfaces themselves have the same default access level as other types.

Specifically, top-level types are internal by default, and nested types are private by default.
