RUNTIME_CLASS为class_name指定的类返回一个指向CRuntimeClass结构的指针。只有用DECLARE_DYNAMIC,DECLARE_DYNCREATE或DECLARE_SERIAL定义的CObject的派生类才能返回CRuntimeClass结构指针。更多的信息参见“Visual C++程序员指南”中的“CObject类”主题。 【示例】 // RUNTIME_CLASS的例子 CRuntimeClass* prt =RUNTIM...
Adds the ability to access run-time information about an object's class when deriving a class fromCObject. คัดลอก DECLARE_DYNAMIC(class_name ) Parameters class_name The actual name of the class. Remarks Add theDECLARE_DYNAMICmacro to the header (.h) module for the class, ...
1. 因为DECLARE_SERIAL重载了＞＞操作符,所以可以保证是调用CMessg类的＞＞函数.2. ＞＞函数实际上调用的是ar的ReadObject(CRuntimeClass*)函数 3. ReadObject首先从文件中读取类判断信息(可能是一个字符串,可能是一个类索引),得到Class对应的ClassName;4. 程序的模块状态中有所有的RuntimeClass的列表,因此,查找...

The correct way to declare an object of the class in C# is:Class_Name Object_Name = new Class_Name(); Consider the below example:using System; namespace MyApplication { class Mobiles { string brand = "Apple"; static void Main(string[] args) { Mobiles mobile = new Mobiles()...
