The parent class in C # invokes the properties, methods of subclasses

We are accustomed to think that the subclass is not visible to the parent class, or that the parent class does not know the existence of subclasses, so the parent class is called the method, property of the child class, the following way, the parent class can call the properties of the subclass, the function of the method, welcome to shoot bricks ...

public class Wechatbasecontroller//Parent class

{

Public Wechatbasecontroller ()

{

}

public string Myuserlist {get; set;}

var result = Wechat.getpage (myuserlist)

}

public class Wechatworkgroupcontroller:wechatbasecontroller//Subclass

{

Public Wechatbasecontroller Basecontroller;

Public Wechatworkgroupcontroller ()

{

Basecontroller = this;

}

Basecontroller.myuserlist = "AAAAAAAAAAAAAA";

}
