syntax is highly expressive, yet it is also simple and easy to learn. The curly-brace syntax of C# will be instantly recognizable to anyone familiar with C, C++ or Java. Developers who know any of these languages are typically able to begin to work productively in C# within a very short time. C# syntax simplifies many of the complexities of C++ and provides powerful features such as nullable value types, enumerations, delegates, lambda expressions and direct memory access, which are not found in Java. C# supports generic methods and types, which provide increased type safety and performance, and iterators, which enable implementers of collection classes to define custom iteration behaviors that are simple to use by client code. In C# 3.0, Language-Integrated Query (LINQ) expressions make the strongly-typed query a first-class language construct.

C# 語(yǔ)法表現(xiàn)力強(qiáng)，而且簡(jiǎn)單易學(xué)。C# 的大括號(hào)語(yǔ)法使任何熟悉 C、C++ 或 Java 的人都可以立即上手。了解上述任何一種語(yǔ)言的開(kāi)發(fā)人員通常在很短的時(shí)間內(nèi)就可以開(kāi)始使用 C# 高效地進(jìn)行工作。C# 語(yǔ)法簡(jiǎn)化了 C++ 的諸多復(fù)雜性，并提供了很多強(qiáng)大的功能，例如可為 null 的值類型、枚舉、委托、lambda 表達(dá)式和直接內(nèi)存訪問(wèn)，這些都是 Java 所不具備的。C# 支持泛型方法和類型，從而提供了更出色的類型安全和性能。C# 還提供了迭代器，允許集合類的實(shí)施者定義自定義的迭代行為，以便容易被客戶端代碼使用。在 C# 3.0 中，語(yǔ)言集成查詢 (LINQ) 表達(dá)式使強(qiáng)類型查詢成為了一流的語(yǔ)言構(gòu)造。
