我将提出一些问题，重点是理解使用dotnet之类的编程概念

托管环境和非托管环境之间的区别是什么? GC的利弊 JIT的利弊 如果我们需要开发应用程序X，我们可以使用dotnet吗?为什么?(这将确定他如何看待dotnet)

我还建议写一些小方法，让他用更好的dotnet类或标准方法重写它们，使它们具有更好的性能。 也写不正确的方法(在任何方面)逻辑或其他，并要求他纠正它们。

我认为这不应该只是问题，我认识一些人，当你面试他们的时候，他们很聪明，但一旦他们进入现实，他们就太完美主义了，我想说，他们在完成任务时很糟糕。

我曾经参加过一次面试，我喜欢第一个雇主给我一份技术问卷，让我在30分钟内填写。如果一个人成功了，他将被要求进行一个1小时的面试，包括性格判断和性格发现问题以及专业术语。

然后我被要求在6个小时内开发一个3页的web应用程序。在应用程序中施加的约束巧妙地涵盖了应用程序开发的主要方面，如小ERD，分层设计，UI一致性，控制特定问题，如在GridView中使用单选按钮，在web页面上从DB中获取和显示图像类型，算法开发，安全性，加密，哈希，数据表示和操作。

第二天，他们进行了30分钟的讨论，讨论开发的应用程序，包括性能瓶颈领域以及设计和使用算法的改进。并在特定条件下进行1小时的可选测试，以改进上一步开发的算法。

所以这需要相当多的时间，但通过这种方式，你可以确保你招聘的人至少知道那些优秀开发人员所必需的概念。

什么是线程?

什么是GC?

除了上面提到的一些问题外，我还喜欢以下几个问题:

委托是什么? 什么是应用程序域? 什么时候使用lock关键字? 标准库泛型集合类是否线程安全? 什么是扩展方法? XmlDocument和XmlReader之间的区别是什么? 如何从应用程序配置文件中读入配置设置?

我在Scott Hanselman的博客上找到了这些列表:

伟大的。net开发人员应该知道什么(更多。net面试问题) ASP。NET面试问题

以下是我从这些文章中归纳出来的最重要的问题。我编辑并重新编排了它们。幸运的是，对于这些问题中的大多数，在Stack Overflow上已经有了很好的答案。只要按照链接(我会尽快更新它们)。

与平台无关的。net问题

What is the difference between a.Equals(b) and a == b? What is boxing? Is string a value type or a reference type? What is the Global Assembly Cache (GAC)? What problem does it solve? What is an Interface and how is it different from a Class? What is Reflection? Conceptually, what is the difference between early-binding and late-binding? When would using Assembly.LoadFrom or Assembly.LoadFile be appropriate? What is an Asssembly Qualified Name? Is it a filename? How is it different? How is a strongly-named assembly different from one that isn’t strongly-named? What does this do? sn -t foo.dll How does the generational garbage collector in the .NET CLR manage object lifetime? What is non-deterministic finalization? What is the difference between Finalize() and Dispose()? (external article) What is the difference between in-proc and out-of-proc? What technology enables out-of-proc communication in .NET? What is FullTrust? Do GAC’ed assemblies have FullTrust? What is the difference between Debug.Write and Trace.Write? When should each be used? What is the difference between a Debug and Release build? Is there a significant speed difference? Why or why not?

ASP。网

What is a PostBack? What is ViewState? How is it encoded? Is it encrypted? Who uses ViewState? Why is it either useful or evil? What Session State providers are available in ASP.NET? What are the pros and cons of each? What is the OO relationship between an ASPX page and its CS/VB code behind file? How would one implement ASP.NET HTML output caching, caching outgoing versions of pages generated via all values of q= except where q=5 (as in http://localhost/page.aspx?q=5)? What are HttpHandlers? What are HttpModules? What is needed to configure a new extension for use in ASP.NET? For example, what if I wanted my system to serve ASPX files with a *.jsp extension? How do cookies work? What is an example of Cookie abuse? What kind of data is passed via HTTP Headers? How does IIS communicate at runtime with ASP.NET? Where is ASP.NET at runtime in the different versions of IIS (5 to 7)?

我被问到的好问题有

你认为。net的优点是什么? 你认为。net的缺点是什么?

看看候选人会提出什么将是很有趣的，你肯定会学到很多关于他/她如何使用这个框架。
