The C# Type System (C# 類型系統)

The type system is the foundation upon which all C# programs are built. The C# Type System will show you how todefine and implement value types effectively, and write more performant and robust code. Real-world code examplesand test cases throughout will elevate your programming with C# and show you how best to implement the principlesyou're learning.

Among the core aspects of working with the type system, you'll learn:

- How user-defined value types, and even simple types, can enhance your code's readability
- How reference and value types differ within C#
- How method parameters and arguments relate to reference and value types
- How differences in copy semantics between value and reference types affect a program's behavior
- How the different methods of value comparisons for equality work behind the scenes
- The unique characteristics and roles of various types in an application, especially how value types go beyond meredata storage
- Why inheritance isn't optimal for value types
- How to measure and evaluate the performance of an app's use of different data types

Whether you're a novice or seasoned programmer, you'll find The C# Type System indispensable in your efforts to turngood code into great.
