Namespaces
The base namespace in the .NET Framework is the System namespace. The System namespace contains classes for garbage collection (discussed shortly), exception handling, data typing, and so much more. The System namespace is just the tip of the iceberg. There are literally dozens of namespaces. Table 24.1 lists some of the more common namespaces, many of which you've used in this book. All the controls that you've placed on forms and even the forms themselves, for example, belong to the System.Windows.Forms namespace. Use Table 24.1 as a guide; if a certain namespace interests you, I suggest that you research it further in the Visual Studio .NET online help.
Table 24.1. Commonly Used Namespaces
| Namespace | Description |
| Microsoft.CSharp | Contains classes that support compilation and code generation using the C# language. |
| Microsoft.VisualBasic | Contains classes that support compilation and code generation using the Visual Basic language. |
| System | Contains fundamental classes and base classes that define commonly used value and reference data types, event handlers, interfaces, attributes, and exceptions. This is the base namespace of .NET. |
| System.Data | Contains classes that constitute the ADO.NET architecture. |
| System.Diagnostics | Contains classes that enable you to debug your application and to trace the execution of your code. |
| System.Drawing | Contains classes that provide access to the Graphical Device Interface (GDI) basic graphics functionality. |
| System.IO | Contains classes that allow reading from and writing to data streams and files. |
| System.Net | Contains classes that provide a simple programming interface to many of the protocols found on the network. |
| System.Security | Contains classes that provide the underlying structure of the CLR security system. |
| System.Web | Contains classes that provide interfaces that enable browser/server communication. |
| System.Windows.Forms | Contains classes for creating Windows-based applications that take advantage of the rich user-interface features available in the Microsoft Windows operating system. |
| System.Xml | Contains classes that provide standards-based support for processing XML. |
