说明：   C#是这样的一种语言，具有C++的特点，象Java一样的编程风格, 并且象Basic一样的快速开发模型。如果你已经知道了C++，本文会在不到一个小时的时间内让你迅速掌握C#的语法。熟悉Java的括会更好，因为Java的程序结构、打包（Packages）和垃圾收集的概念有助于你更快的了解C#。因此在讨论C#的构造时，我会假定你了解C++
(C# is a language with C++ features, like Java as a programming style, and the same rapid development as the Basic model. If you already know C++, this article will be in less than an hour s time for you to quickly grasp the C# syntax. Including familiar with Java will be better, because the Java program structure, packaging (Packages) and the concept of garbage collection will help you quickly understand C#. Therefore, when discussing the construction of C#, I ll assume you know C++)
