What is "global::" in C#?

Question

I was editing a source code for an application I’m writing in C#, which uses GTK+.

I have some knowledge of C#, but did not understand why some variables were written when I mounted the UI in "drag and drop" with the global:: before the names.

See the code snippet:

private Gtk.VBox vbox2;

private global::Gtk.VBox vbox3;

private global::Gtk.Label tituloLogin;

private global::Gtk.Entry entry1;

private global::Gtk.Entry entry2;

What’s this one for global::? What does it mean?

Answer 1

global:: refers to the global namespace. For example, you can reset the class System, look at:

class foo
{
    class System
    {

    }    
}

There, for example, if you want to use Console.WriteLine() in that scope, without conflict, you use:

global::System.Console.WriteLine("teste");

I based my answer on this here.
