**Coursera 课程总结：快速掌握 C# 委托** 本课程旨在帮助 C# 开发者深入理解并熟练运用委托（Delegates）。委托作为 C# 中一项强大且实用的概念，却常常让开发者感到困惑。本课程将通过一系列精心设计的、更贴近实际开发的示例，化繁为简，引导学习者轻松掌握委托的核心知识。 **课程亮点：** * **深入浅出：** 提供比 YouTube 视频更深入的委托概念介绍，通过多个逻辑性强的示例，帮助你识别委托使用的场景，而非仅限于单一的简单例子。 * **循序渐进：** 从委托的基础概念讲起，逐步讲解如何创建和使用委托，对比直接方法调用与委托调用的区别，并展示其在避免代码重复、调用多个方法以及简化代码（通过委托推断）等方面的强大作用。 * **实用技能：** 重点介绍 `Action` 和 `Func` 委托，这是掌握 LINQ 查询的必备知识。 * **为未来铺垫：** 成功掌握委托将为你理解和使用事件（Events）、Lambda 表达式以及 LINQ 打下坚实基础，这些都是现代 C# 开发中不可或缺的技能。 **为何学习委托？** 委托在 .NET Framework 中扮演着至关重要的角色，是解决软件开发中诸多问题的关键。掌握委托可以： * **提升代码复用性：** 减少重复代码，提高开发效率。 * **增强代码灵活性与强大性：** 使你的 C# 代码更具适应性和功能。 * **是事件和 LINQ 的基础：** 在处理事件、编写 LINQ 查询等常见场景中，委托的应用无处不在。 本课程将是你 C# 学习路径上的重要一站，助你真正理解并高效运用委托的强大之处。
Delegates are very useful in C#, but the concept behind delegates might be hard to fully understand, therefore can be confusing for a lot of C# developers. It is inevitable for a C# developer to notice the scenarios while coding, when the use of a delegate could come in very handy. I will be your guide through your delegate learning path, and make it simple for you to understand through my logically built examples. This is my first course, which gives an introduction to the C# delegates. If you follow along, you will understand the delegate related topics much easier: Events, Lambda expressions, LINQ. Anonymous methods, Events, and Lambdas will be also covered in the future sections of this course! LINQ can make your C# code more powerful, and simpler, because it gives you an easy and concise way to query objects. But in order to use it, you first need to understand how delegates work. Why should you take this course instead of watching Youtube videos about delegates? Because this course will give you an in depth introduction to delegatesBecause one simple example may not be enough for you to recognize the situation for a delegate to be useful in software developmentBecause instead of declaring one simple example, I'll cover logically built, more realistic examples to make the topic simple for you to learn and understandYou will learn how Action, and Func work, which is inevitable to know for writing LINQ queries What will you learn in this course? You will learn what a delegate isYou will learn how to create and use delegatesYou will see the difference of direct method invocation and delegate invocationYou will see how useful delegates can be through logical examplesHow to avoid code duplication by using delegatesHow to invoke multiple methods through delegatesHow delegate inference can help us to write simpler codeHow to use Action, Action, Func Why should every C# developer be familiar with the concept of delegates? Delegates are extremely critical part of the.NET FrameworkMight be the solution for a lot of problems when developing a softwareUsing delegates will allow better code reuse to your softwareYour code can become more flexible and powerful when using C# delegatesYou will very commonly use delegates, when using events, creating LINQ queries etc.
