in the c#: When will choose generics?
Main differences: arraylist and list
The main difference between ArrayList and List
List
List The type of type of type provides several advantages compared to ArrayList:
Forced execution type security to prevent you from storing different types of objects in the same episode. This eliminates the need for explicit conversion and reduces the risk of errors.
- List
- Avoid the expenses of boxing and boxing, because it directly stores elements instead of object reference.
LINQ support: List seamlessly integrated with Language Integration (Linq), which is convenient for complex query and conversion of sets. -
Arraylist's abandonment - With the introduction of generics, ARRAYLIST is out of date. ArrayList is not safe, has performance defects, and does not support linq. It is strongly recommended to use List instead of ArrayList in new applications.
Conclusion
In today's C# programming environment, List is superior to ArrayList. Its types of security, performance advantages, and LinQ support make it the first choice collection type of storage and operation data.
The above is the detailed content of ArrayList vs. List in C#: When Should You Choose Generics?. For more information, please follow other related articles on the PHP Chinese website!

C still has important relevance in modern programming. 1) High performance and direct hardware operation capabilities make it the first choice in the fields of game development, embedded systems and high-performance computing. 2) Rich programming paradigms and modern features such as smart pointers and template programming enhance its flexibility and efficiency. Although the learning curve is steep, its powerful capabilities make it still important in today's programming ecosystem.

C Learners and developers can get resources and support from StackOverflow, Reddit's r/cpp community, Coursera and edX courses, open source projects on GitHub, professional consulting services, and CppCon. 1. StackOverflow provides answers to technical questions; 2. Reddit's r/cpp community shares the latest news; 3. Coursera and edX provide formal C courses; 4. Open source projects on GitHub such as LLVM and Boost improve skills; 5. Professional consulting services such as JetBrains and Perforce provide technical support; 6. CppCon and other conferences help careers

C# is suitable for projects that require high development efficiency and cross-platform support, while C is suitable for applications that require high performance and underlying control. 1) C# simplifies development, provides garbage collection and rich class libraries, suitable for enterprise-level applications. 2)C allows direct memory operation, suitable for game development and high-performance computing.

C Reasons for continuous use include its high performance, wide application and evolving characteristics. 1) High-efficiency performance: C performs excellently in system programming and high-performance computing by directly manipulating memory and hardware. 2) Widely used: shine in the fields of game development, embedded systems, etc. 3) Continuous evolution: Since its release in 1983, C has continued to add new features to maintain its competitiveness.

The future development trends of C and XML are: 1) C will introduce new features such as modules, concepts and coroutines through the C 20 and C 23 standards to improve programming efficiency and security; 2) XML will continue to occupy an important position in data exchange and configuration files, but will face the challenges of JSON and YAML, and will develop in a more concise and easy-to-parse direction, such as the improvements of XMLSchema1.1 and XPath3.1.

The modern C design model uses new features of C 11 and beyond to help build more flexible and efficient software. 1) Use lambda expressions and std::function to simplify observer pattern. 2) Optimize performance through mobile semantics and perfect forwarding. 3) Intelligent pointers ensure type safety and resource management.

C The core concepts of multithreading and concurrent programming include thread creation and management, synchronization and mutual exclusion, conditional variables, thread pooling, asynchronous programming, common errors and debugging techniques, and performance optimization and best practices. 1) Create threads using the std::thread class. The example shows how to create and wait for the thread to complete. 2) Synchronize and mutual exclusion to use std::mutex and std::lock_guard to protect shared resources and avoid data competition. 3) Condition variables realize communication and synchronization between threads through std::condition_variable. 4) The thread pool example shows how to use the ThreadPool class to process tasks in parallel to improve efficiency. 5) Asynchronous programming uses std::as

C's memory management, pointers and templates are core features. 1. Memory management manually allocates and releases memory through new and deletes, and pay attention to the difference between heap and stack. 2. Pointers allow direct operation of memory addresses, and use them with caution. Smart pointers can simplify management. 3. Template implements generic programming, improves code reusability and flexibility, and needs to understand type derivation and specialization.
