Absolute/outer and inner namespace confusion in C#

Question

using Foo.Uber;

namespace MyStuff.Foo
{
    class SomeClass{
        void DoStuff(){
            // I want to reference the outer "absolute" Foo.Uber
            // but the compiler thinks I'm refering to MyStuff.Foo.Uber
            var x = Foo.Uber.Bar();
        }
    }
}

How could I solve this? Just moving the using statement inside my namespace doesn't help.

Answer 1

You can do this using a namespace alias qualifier (typically global::) to refer to the default / root namespace:

global::Foo.Uber

Answer 2

Alias the namespace in the using statement:

using ThatOuterFoo = Foo.Uber;
...
...
//Some time later...
var x = ThatOuterFoo.Bar();
