Question

我正在使用UI表单使用VS 2013。在MyForm.h中有一个代码

class A
{
public:
    A();
    ~A();
private:
};

void b()
{
    A var;
}

我收到了这些错误：

Error   2   error LNK2028: unresolved token (0A00000A) "public: __thiscall A::A(void)" (??0A@@$$FQAE@XZ) referenced in function "void __cdecl b(void)"
Error   3   error LNK2028: unresolved token (0A00000B) "public: __thiscall A::~A(void)" (??1A@@$$FQAE@XZ) referenced in function "void __cdecl b(void)"
Error   4   error LNK2019: unresolved external symbol "public: __thiscall A::A(void)" (??0A@@$$FQAE@XZ) referenced in function "void __cdecl b(void)"
Error   5   error LNK2019: unresolved external symbol "public: __thiscall A::~A(void)" (??1A@@$$FQAE@XZ) referenced in function "void __cdecl b(void)"

我已经用Google搜索了大约两个小时，但仍然没有结果。

你必须定义构造函数和析构函数，如：

class A{
public:
    A();
    ~A();
private:
};
  A::A(){
}
  A::~A(){
}
void b()
{
  A var;
}

LNK2028未解决的令牌＆amp; LNK2019未解析的外部符号
