A Singleton class is often used when you want to control the instantiation of a class to a single instance throughout the lifetime of an application. This can be useful in scenarios where you need to manage a shared resource...

instance = new SingletonPattern1();这一块可以扩展，直接创建类，也可以创建借口，或直接载入dll等 单例模式是我们学习设计模式的第一课，这个代码已经无懈可击了，代码参考 using System; namespace SingletonPattern { public class SingletonPattern1 { /// ///单例锁对象 /// private static...
格式如下: #pragma code_seg( [ [ { push | pop}, ] [ identifier, ] ][ "segment-name" [, "segment-class" ] ]) 该指令用来指定函数在.obj文件中存放的节,观察OBJ文件可以使用VC自带的dumpbin命令行程序 ,如果code_seg没有带参数的话,则函数在OBJ文件中存放在默认在.text节中。 push (可选参数...
