#pragma region 嵌套多个命名空间举例
     namespace Group
     {
          namespace Company
          {
               namespace Department
               {
                    class __declspec(dllexport) classA
                    {
                         //........
                         //.....
                         //..
                    };
               }
          }
     }
#pragma endregion

 

class A;

这是的classA才会被引到。
