Mocking global variables in C#
C# does not allow the declaration of true global variables (existing outside any class scope) like other languages. However, there is a way to simulate this functionality efficiently.
Static class method
The standard solution is to create a static class that contains the global variables you want to share between all classes in your application. An example is as follows:
public static class 全局變量 { public const int BUFFER_SIZE = 512; public static string FILE_NAME = "Output.txt"; public static readonly string CODE_PREFIX = "US-"; }
How to use
To access these global variables, you simply reference them in your code:
string code = 全局變量.CODE_PREFIX + value.ToString();
Namespace considerations
If you want to access these variables from a different namespace, you have two options:
- Declare the
全局變量
class outside of any namespace, making it part of the global application namespace. - Include the appropriate
全局變量
directive in the namespace from which you want to access the variables in theusing
class.
Advantages
- Centralized definition of global variables, making them easily accessible from anywhere in the code base.
- Supports constants and modifiable variables.
- Accessible from any namespace ensuring easy sharing of data.
Conclusion
By using static classes, C# developers can effectively simulate the behavior of global variables, providing a convenient and easy-to-maintain method for sharing data across multiple classes and namespaces.

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
