C#是微软公司发布的一种面向对象的、运行于.NET Framework之上的高级程序设计语言。并定于在微软职业开发者论坛(PDC)上登台亮相。C#是微软公司研究员Anders Hejlsberg的最新成果。C#看起来与Java有着惊人的相似；它包括了诸如单一继承、接口、与Java几乎同样的语法和编译成中间代码再运行的过程。但是C#与Java有着明显的不同，它借鉴了Delphi的一个特点，与COM（组件对象模型）是直接集成的，而且它是微软公司 .NET windows网络框架的主角。(C# is an object-oriented programming language published by the Microsoft Corp, which runs on the.NET Framework. And it is scheduled to appear on the platform of the Microsoft Professional Developer Forum (PDC). C# is the latest achievement of Anders Hejlsberg, a Microsoft Corp researcher. C# looks surprisingly similar to Java, which includes almost all the same syntax as single inheritance, interface, Java and the process of running it into intermediate code. But C# is obviously different from Java. It draws on a feature of Delphi and is directly integrated with COM (component object model), and it is the leading role of Microsoft Corp.NET windows network framework.)
