Which component is used to represent namespaces in CodeDOM?

  1. CodeNamespaceImport

  2. CodeTypeDeclaration

  3. CodeNamespace

  4. CodeCompileUnit

The correct answer is: CodeNamespace

The component used to represent namespaces in CodeDOM is indeed the CodeNamespace. This class serves as a container for types, allowing developers to organize their code logically within a specified namespace. By utilizing CodeNamespace, you can group related classes, interfaces, and other types together, supporting better code organization and helping to avoid naming conflicts that can arise when similar type names are used across different parts of an application. In the context of CodeDOM, CodeNamespace not only helps to define the scope of the types within it but also allows for the importation of other namespaces using the CodeNamespaceImport class. This aids in referencing types that exist in different namespaces, thus enhancing code modularity and maintainability. CodeTypeDeclaration, on the other hand, represents a class, struct, interface, or enumeration but does not have a direct role in representing namespaces. Similarly, CodeCompileUnit is a broader structure that represents a complete compilation unit, which may include multiple namespaces, classes, and other top-level constructs but does not specifically target namespace representation itself.
