RefClass(&aNum);
错了，应该是
RefClass(*aNum);

[meimeizsq]

RefClass(&aNum); 是引用
函数调用应该是
RefClass(*aNum);

或者你把你的引用改成指针参数
void __fastcall RefClass(TComputeNum* aNum)
{
aNum->mNum= 5;
aNum->dNum = 6;
}
调用是 RefClass(aNum);

[leeicescri]

改成RefClass(*aNum);

[jxw1987628]

RefClass(&aNum); -------------> RefClass(*aNum);

[tangx100]

RefClass(*aNum);
