C#调用C++DLL 在合作开发时，C#时常需要调用C++DLL。研究了一下C#,发现其强大简洁, 在跨语言调用方面封装的很彻底,提供了强大的API与之交互.这点比JNA方便多了. Java与C#都只能调用C格式导出动态库,因为C数据类型比较单一,容易映射. 两者都是在本地端提供一套与之映射的C#/java描述接口,通过底层处理这种映射关系达到调用的目的. 1、调用例子(例子中提供了传值调用和传址调用两种方法阅读详情

下面链接的内容为如下代码，是通过c#对NPOI的使用来操作excel，我现在想通过c++对下列代码进行封装，从而达到在c++平台上进行使用的目的，但是未成功，不知道哪位大神有过类似经历，求指教~~~~积分不多，多多见谅。江湖救急~~~~~
