C# interview questions: What is LINQ, and How Does It Work in C#?
•
What is LINQ, and How Does It Work in C#? (什么是 LINQ，它在 C# 中是如何工作的？) LINQ (Language Integrated Query) is a powerful querying feature in C# that allows developers to write expressive, declarative queries against a variety of data sources in a consistent way. LINQ (语言集成查询) 是 C# 中一个强大的查询功能，它允许开发人员以一致的方式对各种数据源编写简洁、声明式的查询。 LINQ provides…

C# interview questions: SOLID Principles in C#
•
SOLID Principles in C# (SOLID 原则在 C# 中的应用) SOLID is an acronym for five design principles that help developers create more maintainable, flexible, and scalable code. These principles are foundational to object-oriented design and help improve software quality. SOLID 是五个设计原则的缩写，这些原则帮助开发者编写更易维护、灵活且可扩展的代码。它们是面向对象设计的基础，有助于提升软件质量。 1. S – Single Responsibility Principle (单一职责原则) Definition: A class…

C# interview questions: How Do You Prevent Memory Leaks in C#?
•
How Do You Prevent Memory Leaks in C#? Memory leaks occur when objects are no longer in use but are not properly released from memory, leading to inefficient memory usage. In C#, the Garbage Collector (GC) typically handles memory management, but improper coding patterns or handling of resources can still…

C# interview questions: What is Dependency Injection, and Why is it Useful in C#?
•
What is Dependency Injection, and Why is it Useful in C#? Dependency Injection (DI) is a design pattern used to achieve Inversion of Control (IoC) between classes and their dependencies. In simple terms, Dependency Injection allows objects (often called dependencies) to be provided to a class rather than letting the…

C# interview questions: What is the Difference Between `IEnumerable` and `IQueryable`?
•
What is the Difference Between IEnumerable and IQueryable? In C#, both IEnumerable<T> and IQueryable<T> are used to represent collections of data that can be queried. However, they have significant differences in how they execute queries and where they are most effective. Understanding these differences is crucial when working with LINQ…

C# interview questions: How Does Garbage Collection Work in C#?
•
How Does Garbage Collection Work in C#? Garbage collection (GC) in C# is a memory management system provided by the .NET runtime (CLR). Its purpose is to automatically manage memory allocation and release unused objects, helping developers avoid memory leaks and freeing them from manual memory management tasks like in…

C# interview questions: Difference Between `Task` and `Thread` in C#
•
Difference Between Task and Thread in C In C#, both Task and Thread are used for parallel execution of code, but they serve different purposes and operate at different levels of abstraction. Understanding the difference between these two is essential for building efficient, responsive, and scalable applications. Quick Overview Thread:…

C# 101: Exception Handling in C#
•
Exception Handling in C Exception handling in C# allows developers to manage and respond to runtime errors in a controlled and predictable manner. The primary mechanism used for exception handling in C# includes the try, catch, finally, and throw keywords. This mechanism helps ensure that applications continue running smoothly even…

C# 101: Exploring Task Parallelism and Error Handling in Asynchronous Code
•
Exploring Task Parallelism and Error Handling in Asynchronous Code In advanced asynchronous programming, task parallelism allows multiple tasks to run simultaneously, leveraging multiple processors or cores to maximize performance. In parallel, understanding error handling strategies ensures that exceptions in asynchronous tasks are captured and managed effectively. In this section, we…

C# interview questions: Purpose of `async` and `await` in C#
•
Purpose of async and await in C# (With Key Points, Tips, Code Examples) In C#, the async and await keywords allow for easier and more efficient asynchronous programming. This helps developers write code that doesn’t block the main thread, improving the responsiveness of the application, especially for I/O-bound operations such…
