Introduction C# is a language with the features of C++, programming style like Java and rapid application model of BASIC. If you already know the C++ language, it will take you less than an hour to quickly go through the syntax of C#. Familiarity with Java will be a plus, as Java program structure, the concept of packages and garbage collection will definitely help you learn C# more quickly. So while discussing C# language constructs, I will assume, you know C++. This article discusses the C# language constructs and features using code examples, in a brief and comprehensive way, so that you just by having a glance at the code, can understand the concepts. Note: This article is not for C# gurus. There must be some other beginner's articles on C#, but this is yet another one.

C# API调用例子，供初学者参考。 调用格式 using System.Runtime.InteropServices; //引用此名称空间，简化后面的代码 //使用DllImportAttribute特性来引入api函数，注意声明的是空方法，即方法体为空。 [DllImport("user32.dll")] public static extern ReturnType FunctionName(type arg1,type arg2,...); //调用时与调用其他方法并无区别
