As in previous versions of C#, the namespace keyword is used to declare a scope. Thislets you organize your code and prevents identifier collisions (forexample, two different classes with the same name), especially whenusing third-party components.

Any object that is not defined within a specific namespace is in theglobal namespace. Objects in the global namespace are available to objectsin any other namespace. If a name collision occurs, however, you willneed a way to specify that you want the object in the globalnamespace rather than in the local namespace.

---

Note: The global namespace qualifier allows you to specify anidentifier in the (default) global namespace rather than in the localnamespace .

---

To access objects in the global namespace, you use the new globalnamespace qualifier ( global: :), as shown in .

using System; namespace GlobalNameSpace{ class Program { // create a nested System class that will provide // a set of utilities for interacting with the // underlying system (conflicts with System namespace) public class System { } static void Main(string[ ] args) { // flag indicates if we're in a console app // conflicts with Console in System namespace bool Console = true; int x = 5; // Console.WriteLine(x); // won't compile - conflict with Console // System.Console.WriteLine(x); // conflicts with System global::System.Console.WriteLine(x); // works great. global::System.Console.WriteLine(Console); } }}
