HelperClass .

例如:我有两个抽象派生类。我创建 ClassA 然后电话 TakeAction 采取行动 助手类 class the method 解决问题`。

我的问题是:我怎样才能再次呼叫a A类 助手类 ? 因为SolveProblem有一些逻辑,它将决定是否返回。

class Program {
    static void Main(string[] args) {
        var classA = new ClassA();
        classA.StartOperation();
    }
}

public abstract class ClassAbstract {
    public abstract void StartOperation();

    public void TakeAction() {
        var helper = new HelperClass();
        helper.SolveProblem(DayOfWeek.Sunday);
    }

    public abstract void WeekDayOperation();
    public abstract void WeekEndOperation();
}

public class ClassA : ClassAbstract {
    public override void StartOperation() {
        TakeAction();
    }

    public override void WeekDayOperation() {
    }

    public override void WeekEndOperation() {
        throw new NotImplementedException();
    }
}

public class ClassB : ClassAbstract {
    public override void StartOperation() {
        TakeAction();
    }

    public override void WeekDayOperation() {
    }

    public override void WeekEndOperation() {
        throw new NotImplementedException();
    }
}

public class HelperClass {
        public void SolveProblem(DayOfWeek day) {
        //Problem solved. I need to call "CallThisMethod" who called this helper class
        //How to I Call
        switch(day) {
            case DayOfWeek.Sunday:
            case DayOfWeek.Saturday:
                ClassA.WeekEndOperation();
                break;
            case DayOfWeek.Friday:
                FridayOperations();
                break;
            default:
                ClassA.WeekDayOperation();
                break;
        }
    }

    public void FridayOperations() {

    }
}

一种解决方案是传递类型为的实例: ClassAbstract SolveProblem 。然后可以使用此变量调用该方法。

public void SolveProblem(DayOfWeek day, ClassAbstract c)
{
    //Problem solved. I need to call "CallThisMethod" who called this helper class
    //How to I Call
    switch (day)
    {
        case DayOfWeek.Sunday:
        case DayOfWeek.Saturday:
            c.WeekEndOperation();
            break;
        case DayOfWeek.Friday:
            FridayOperations();
            break;
        default:
            c.WeekDayOperation();
            break;
    }
}

this )在的基本实现中调用此方法时 TakeAction 在 类摘要 :

public abstract class ClassAbstract
{
    public abstract void StartOperation();

    public void TakeAction()
    {
        var helper = new HelperClass();
        helper.SolveProblem(DayOfWeek.Sunday, this);
    }

通过以下现象 polymorphism WeekEndOperation 和 WeekDayOperation 班级的 ClassA
