加載DLL文件並調用DLL函數實例

 

#include <stdio.h>
#include <windows.h>
typedef int (*lpAddFunc)(int,int);
int main()
{

    lpAddFunc sum;
    HINSTANCE hDLL = ::LoadLibrary("MyDll.dll");
    if(hDLL)
    {
        sum = (lpAddFunc)::GetProcAddress(hDLL,"sum");
        if(sum)
        {
            int result = sum(1,2);
            printf("%d",result);
        }
        ::FreeLibrary(hDLL);
    }
    return 0;
}
