看了第一篇感觉没啥用对吧,来点稍微有用的。
1、先建个c#工程,依次 file -> new -> project,选择 visula c# -> console application,写工程名,点 ok。
2、再建个c++ dll工程。依次 file -> add -> new project。选择 visual -> win32 console application,点 ok -> next,选择 dll -> finish。
3、建立cli工程。依次 file -> add -> new project。选择 visula c++ -> clr -> class library,写工程名,点 ok。
4、创建结束,开始配种,啊呸!配置。
1)、c#工程默认平台any cpu,强迫症犯了,改成x86,编译下,生成目标debug路径:.\bin\x86\debug。
2)、修改c++工程输出目录、cli工程输出目录、cli工程库引入路径等为上方目录。
3)、修改cli引入头文件路径为包含CppDll.h的路径。
4)、依次编译c++工程,cli工程
5)、c#工程导入CliDll,依次选择 c#工程 -> references -> 点右键 -> add reference -> browse -> 选择debug路径下由cli工程生成的dll文件。
6)、编译c#工程,最后运行。
