c# - 从继承另一个的类中获取变量

Question

我有任意数量的继承 classToBeInherited 的类，classThatInherits、anotherClassThatInherits 等。然后我有一个方法 b，它需要能够从继承 classToBeInherited 的类访问 myValue。如果不进行转换，我如何实现这一目标？

//This class will be inherited by other classes
public class classToBeInherited {
    public bool isSomething { get; set; }
}

//This class with inherit 'classToBeInherited'
public class classThatInherits : classToBeInherited {
    public int myValue { get; set; } //this needs to be accessable...
}

//...And so will this class
public class anotherClassThatInherits : classToBeInherited {
    public int myValue { get; set; }
}

private class normalClass {

    private void a() {
        classThatInherits cti = new classThatInherits();
        b(cti);

        anotherClassThatInherits acti = new anotherClassThatInherits();
        b(acti);
    }

    private void b(classToBeInherited c) {
        //***
        //get myValue from the classes that inherit classToBeInherited
        //***
    }
}

Answer 1

将 myValue 移至 classToBeInherited:

public class classToBeInherited {
    public bool isSomething { get; set; }
    public abstract int myValue { get; set; }
}

然后在 classThatInherits 和 anotherClassThatInherits 中使用 public override int myValue { get;放; } 来实现该属性。

当然，如果只有一些类需要 myValue，那么您可以拥有 virtual 而不是 abstract 属性。
