这可能不是你想听到的，但我建议不要关注狭隘的技术，而是一般的编程和解决问题的技能。扎实的开发人员可以快速学习您想让他们做的任何事情。

举个例子，我并不是一个支持紧凑框架的人，所以如果你这么做的话，我可能会让你的面试失败。但如果我需要使用它，我可以做一些研究，然后直接投入。

Joel的书《Smart and Gets Things Done》为招聘开发者提供了很好的建议，其中有大量关于该问哪些问题的内容。我强烈推荐它。

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 thread and a process? What is the difference between an EXE and a DLL? What is strong-typing versus weak-typing? 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? What is the difference between: catch (Exception e) {throw e;} and catch (Exception e) {throw;} ? What is the difference between typeof(foo) and myFoo.GetType()? What is the purpose of XML Namespaces? What is the difference between an XML "Fragment" and an XML "Document"? (XML Basics) How would you validate XML using .NET?

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)?

没有,真的。也许有一些非常简单的问题，世界上最聪明的人也不知道答案。不是因为他们很难，只是因为他们还没有遇到过。你应该着眼于整个程序包和开发人员的技能，而不是他们是否能够回答任意的问题。

如果这个问题很简单，可以用一两句话回答，那么告诉不知道的人也很容易。你应该寻找他们对概念的理解和推理能力，而不是他们回答“每个。net开发人员都应该能够回答”的问题的能力。

了解引用类型和值类型之间的区别。

要知道事件是作为硬引用存储的(也就是说，要记得取消事件注册，否则应用程序将会泄漏内存)。

字符串是不可变的。

以下是我用来筛选c#程序员职位的程序员的一些方法:

引用类型和值类型之间的区别是什么?

解释IDisposable接口，c#语言构造需要它，以及如何实现它。

如果将null作为参数传递给具有不允许该参数为空的契约的方法，您将抛出哪个异常?

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?
