由上几点,感觉class static method主要用处就是做为类属性的访问器,以及纯粹的静态方法。 其它用处,亦未知。 TMyClass类其实现代码如下: {TMyClass}varFMyClass: TMyClass;classfunctionTMyClass.GetInstance: TMyClass;beginifFMyClass =nilthenFMyClass := Self.Create;//这里Self,指的是TMyClass类;在static方法...
namespaced functions, unless declared "friend" have no access to the class' internals, whereas static methods have. This means, for example, that when maintaining your class, if you need to change your class' internals, you will need to search for side effects in all its methods, including...
Static classes can't be instantiated in C#. You access the members of a static class by using the class name itself.
classTestClass{// Methods, properties, fields, events, delegates// and nested classes go here.} 备注 在C# 中仅允许单一继承。 也就是说,一个类仅能从一个基类继承实现。 但是,一个类可实现多个接口。 下表显示类继承和接口实现的一些示例:
