use of :: operator

//if we have System as the class and Console as the static variable, so

// how can we write System.Console.WriteLine.

//The operator :: is known as the namespace alias qualifier.

//global is the namespace.

// :: is used between global and System namespaces

namespace dd
{
    class System
    {
        static int Console=10;
        static void Main()
        {
            global::System.Console.WriteLine(Console);

        }
    }

}

//output will be 10.
