7.2 Packaging Code in C#
So far, we’ve used properties, methods and classes to package code. We’ll present additional packaging mechanisms in later chapters. C# apps are written by combining your properties, methods and classes with predefined properties, methods and classes available in the .NET Framework Class Library and in other class libraries. Related classes are often grouped into namespaces and compiled into class libraries so that they can be reused in other apps. You’ll learn how to create your own namespaces and class libraries in Chapter 15. The Framework Class Library provides many predefined classes that contain methods for performing common mathematical calculations, string manipulations, character manipulations, input/output operations, graphical user interfaces, graphics, multimedia, printing, file processing, database operations, networking operations, error checking, web-app development, accessibility (for people with disabilities) and more.
