如何返回类的属性而不是类本身？ [英] How to return a property of the class instead of the class itself?

问题描述

我目前正在使用隐式运算符将类转换和转换为 Class2 。

I'm currently converting and casting from Class to Class2 using the implicit operator.

想要做的是，每当我提到 foo（Class< Class2>） ，我想要 Goo（Class） 以便我可以直接访问它的公共属性，而不必将它首先投射到一个新的变量。

But what I want to do is, that, whenever I refer to foo (Class<Class2>), I'd like for Goo(Class) to be returned so that I can access the public Properties of it directly, without having to cast it first into a new variable.

换句话说，当我访问 Class< Class> 时，我想要返回Goo。

In other words, I want that when I access Class<Class>, I'd like Goo to be returned.

我知道我可能无法正确解释，所以请在评论部分自由地提出，以便我可以尝试更好地填补我的意思。先感谢！

I'm aware I might have not been able to explain properly so feel free to ask in the comment section so that I can try to fill in even better on what I mean. Thanks in advance!

class Class<T> where T : new()
{
    public T Goo;

    public Class() { Goo = new T(); }

    public static implicit operator T(Class<T> Loo)
    {
        return Loo.Goo;
    }
}

class ClassX
{
    public byte[] SharedData;

    public ClassX() { }
}

class Class2 : ClassX
{
    public byte Data;

    public Class2() { }
}

class Class3 : ClassX
{
    public string Data;

    public Class3() { }
}

class Program
{
    static void Main(string[] args)
    {
        Class<Class2> foo = new Class<Class2>();
        Class2 poo = foo;

        foo.Data = 0xFF; // Error - I want this to work, tho.
        poo.Data = 0xFF; // Works - Not what I want to use.

        System.Console.ReadLine();
    }
}

推荐答案

你应该能够很简单地在类中实例化它。

you should be able to do it quite simply as you have already instantiated it within the class.

Class2 main = foo.Goo
