=========================================

C# 在 3.0 版和 5.0 版对面向对象的语言添加了主要的新功能。With versions 3.0 and 5.0, C# had added major new features in an object-oriented language. 版本 6.0 随 Visual Studio 2015 一起发布，通过该版本，它不再推出主导性的杀手锏，而是发布了很多使得 C# 编程更有效率的小功能。With version 6.0, released with Visual Studio 2015, it would go away from doing a dominant killer feature and instead release many smaller features that made C# programming more productive. 以下介绍了部分功能：Here are some of them:

• 静态导入Static imports
• 异常筛选器Exception filters
• 自动属性初始化表达式Auto-property initializers
• Expression bodied 成员Expression bodied members
• Null 传播器Null propagator
• 字符串内插String interpolation
• nameof 运算符nameof operator
• 索引初始值设定项Index initializers

其他新功能包括：Other new features include:

• Catch/Finally 块中的 AwaitAwait in catch/finally blocks
• 仅限 getter 属性的默认值Default values for getter-only properties

这些功能每一个都很有趣。Each of these features is interesting in its own right. 但从整体来看，可以发现一个有趣的模式。But if you look at them altogether, you see an interesting pattern. 在此版本中，C# 消除语言样本，让代码更简洁且更具可读性。In this version, C# eliminated language boilerplate to make code more terse and readable. 所以对喜欢简洁代码的用户来说，此语言版本非常成功。So for fans of clean, simple code, this language version was a huge win.

除了发布此版本，他们还做了另一件事，虽然这件事本身与传统的语言功能无关。They did one other thing along with this version, though it's not a traditional language feature in itself. 他们发布了 Roslyn 编译器即服务。They released Roslyn the compiler as a service. C# 编译器现在是用 C# 编写的，你可以使用编译器作为编程工作的一部分。The C# compiler is now written in C#, and you can use the compiler as part of your programming efforts.
