Text/Zhu Jiqian I remember when I first came into contact with JAVA object-oriented programming, if I encountered a large number of process judgment statements, almost the whole screen was filled with if-else statements. There were so many that I forgot where the head and where was the tail. However, even if the screen was filled […]

BindingFlags in C#: Core enumeration types for reflection
The C# programming language provides a very powerful feature: reflection, which allows us to dynamically obtain and operate type information at runtime. Reflection can be used to implement many advanced functions, such as dynamically loading assemblies, creating object instances, calling methods, accessing fields and properties, etc. To use reflection, we need to use some classes […]
2023/11/8–C#–Structures, enumerations, delegates…
1. Structure: In C#, a structure (struct) is a user-defined value type used to encapsulate a set of related data fields. Unlike classes, structures are value types, while classes are reference types. This means that instances of structures are copied when assigned to variables, passed to methods, or passed as function arguments, whereas instances of […]
“Understanding custom types: structures, enumerations, unions”
Foreword This article will introduce three custom types in C language: structure, enumeration and union. These data types are very important in C language, they allow programmers to create their own data types to meet specific needs. By understanding these data types, you can better grasp the characteristics and applications of C language. 1. Structure […]

Strategy + enumeration to eliminate if-else elegantly
Foreword: I believe that when you first came into contact with JAVA object-oriented programming, if you encountered a large number of process judgment statements, almost the whole screen was filled with if-else statements. There were so many that you forgot where the head is and where the tail is. So, how to avoid using if-else […]
