publice class Sample {private Sample means;}在Sample类的定义中引用Sample的类型变量如何去理解?
不是在定义完一个类后才可以声明那种类型的变量吗?

publice class Sample
{
private static Sample _means= null; //定义Sample类型的变量 _means
public static Sample Means
{
get
{
return _means; //在Sample类的定义中引用Sample的类型变量
}
private set
{
_means= value;
}
}
static Sample ()
{
_means= new Sample (); //静态构造函数,实例化一个Sample类
}
}

publice class Sample {private Sample means;}在Sample类的定义中引用Sa 有如下类定义 class Sample{ public：Sample(int x):ref(x){} //1 priva 外贸中sample order和sample goods golden sample 与approve sample的区别? salesmen sample的中文翻译?
