管理信息系统开发语言之c#简介------外文翻译.doc

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# 语法表现力强，而且简单易学。C# 的大括号语法使任何熟悉 C、C++ 或 Java 的人都可以立即上手。了解上述任何一种语言的开发人员通常在很短的时间内就可以开始使用 C# 高效地进行工作。C# 语法简化了 C++ 的诸多复杂性，并提供了很多强大的功能，例如可为 null 的值类型、枚举、委托、lambda 表达式和直接内存访问，这些都是 Java 所不具备的。C# 支持泛型方法和类型，从而提供了更出色的类型安全和性能。C# 还提供了迭代器，允许集合类的实施者定义自定义的迭代行为，以便容易被客户端代码使用。在 C# 3.0 中，语言集成查询 (LINQ) 表达式使强类型查询成为了一流的语言构造。
