应用程序调用DLL中的变量也有两种方法。

第一种是隐式链接：

#include <stdio.h>
#include "DLLSample.h"

#pragma comment(lib,"DLLSample.lib")

int main(int argc, char *argv[])
{
　printf("%d ", DLLSample);
　return 0;
}

第二种是显式链接：

#include <iostream>
#include <windows.h>

int main()
{
      int my_int;
      HINSTANCE hInstLibrary = LoadLibrary("DLLSample.dll");

      if (hInstLibrary == NULL)
      {
      FreeLibrary(hInstLibrary);
      }
      my_int = *(int*)GetProcAddress(hInstLibrary, "DLLData");
      if (dllFunc == NULL)
      {
      FreeLibrary(hInstLibrary);
      }
      std::cout<<my_int;
      std::cin.get();
      FreeLibrary(hInstLibrary);
      return(1);
}
