使用旧的C＃教程是否有害 [英] Is it harmful to use old C# tutorials
问题描述
为了学习c＃我在Youtube上使用旧教程EG Kudvenkat
这些教程是从2010年开始的，当时c＃3.0刚刚发布但是现在c＃7.0已经发布了使用书籍S Svetlin Nakov，Veslin Kolev& Co的C＃计算机编程基础。
从长远来看如果我使用这么老的教程还是可以学习c＃
我的尝试：
Svetlin Nakov，Veslin Kolev &安培; Co的计算机编程和Kudvenkat的基础
我不会说他们不健康，只是有些功能已经过时而有些功能已经过时了添加 - 虽然一些是为了向后兼容。 C＃语言本身是相同的，只是添加了一些语法糖来支持字符串插值，异步编程，值类型或引用类型的性能改进。
我相信C＃的灵魂是相同的，提供了一种多范式的编程语言。这没有改变。做事方式有所改变，lambdas，async / await，LINQ和其他功能引入了令人惊奇的编写程序的新方法，在编译器上留下了实践。我建议继续阅读，因为，作为一个比喻，旧版本的C＃教你如何进行异步编程，而较新版本的C＃可以帮助你编写可读和可调试的异步代码。
无论如何，对于C＃语言的功能和更新，请访问此链接并查看更改内容， C＃的历史 - C＃指南| Microsoft Docs [ ^ ]。我还建议使用Microsoft提供的教程，它们是最简单，直接和更新的教程;有时也不是初学友好的。

您只会错过该语言的最新成员，但初学者的概念保持不变。
以下是参考文献的链接由语言作者撰写的关于C和C ++的书籍。注意，C是C ++的祖先，所以知道C对C ++总是有用。

虽然其他解决方案建议引用C或C ++指南，两者都与C＃共享类似的语法，但不建议从这些指南开始。 C / C ++和C＃之间存在显着差异。相反，第一个解决方案（来自Azfaal Ahmad Zeeshan）提供了更准确的链接。
我建议使用以下附加链接，其中突出显示添加的一些功能随着C＃语言的发展。

For learning c# i use old tutorials E.G Kudvenkat on Youtube
These tutorials are from 2010 when c# 3.0 was only released but now c# 7.0 is released although i do use books E.G Svetlin Nakov, Veslin Kolev & Co's Fundalmentals of c# Computer Programming.
Will it be a problem in the long run if i use such old tutorials or is it ok for learning c#
What I have tried:
Svetlin Nakov, Veslin Kolev & Co's Fundalmentals of c# Computer Programming and Kudvenkat
I will not say that they are not healthy, just that some features get outdated and some are added — while some are kept for backward compatibility. C# language itself is the same, just some syntactic sugars have been added to support string interpolation, asynchronous programming, performance improvements for value-type or reference-types.
I believe the soul of C# is same, providing a multi-paradigm programming language. That hasn't changed. Ways of doing things has changed a bit, lambdas, async/await, LINQ and other features introduce amazing new ways to write the programs, leaving practices on the compiler. I would recommend keep reading that, because, as a metaphor, older versions of C# teach you how asynchronous programming works, and newer versions of C# help you write readable and debuggable asynchronous code.
Anyways, for the features and updates in C# language please visit this link and check out what has changed, The history of C# - C# Guide | Microsoft Docs[^]. I also recommend using the tutorials provided by Microsoft, they are simplest, straight-forward, and updated tutorials; sometimes not a beginner friendly ones too.

You will only miss the latest additions to the language, but the concepts stay the same for a beginner.
Here is links to references books on C and C++ by the authors of the languages. Note than C is the ancestor of C++, so knowing C is always useful with C++.

C++ Programing Language[^]
While other solutions advise referencing C or C++ guides, both of which share a similar syntax with C#, I do not advise starting with those guides. There are significant differences between C/C++ and C#. Instead, the first of the solutions (from Azfaal Ahmad Zeeshan) provides more accurate links.
I suggest the following additional links, which highlight some of the features that were added as the C# language evolved.
