C#调用VC++动态链接库的研究

Study on C# Invoking the Dynamic Link Library Developed by VC ++

C#与C++混合编程是最常见的混合编程方式。用C#调用C++编写的动态链接库存在很多需要解决的问题。对C#调用C++编写的动态链接库的必要性及托管与非托管的概念进行了描述,并对C#调用C++时面临的导入DLL、数据类型转换、结构体参数的处理、指向结构体的指针及在C#中用结构体模拟共用体等常见问题进行研究并给出必要的示例代码。

Combined C# with C ＋ ＋ is the most normally used mixed programming method. There are many problems to be solved while use C# to invoke the dynamic link library（DLL） developed by C ＋ ＋. The necessi- ty of invoking C ＋ ＋ developed dynamic link library by C# is described and the concept of managed and un- managed code is explained. The problems such as import DLL, data type convert, struct parameter, pointer and parameter etc. are researched and necessary example code is listed.
