有没有办法从父参考构造子对象？ [英] Is there a way to construct child object from parent reference?

问题描述

考虑我有2类：

public class ComplicatedParent
{
    // Lots of data
}

public class SimpleChild : ComplicatedParent
{
    public string SomeAdditionalData { get; set; }

    public SimpleChild(string arg) : base()
    {
        SomeAdditionalData = arg;
    }
}

和 SomeFunction 返回 ComplicatedParent 的实例。有没有构造孩子从父母的参考一个简单的方法，preserving父母的状态？

And SomeFunction that returns instance of ComplicatedParent. Is there a simple way to construct child from parent's reference, preserving parent's state?

实际上 ComplicatedParent 类和 SomeFunction 是第三方的，所以我不能改变的。

Actually ComplicatedParent class and SomeFunction are third party so I can't change them.

推荐答案

您无法自动在语言做到这一点。您可以Aut​​omaper或手动分配去做。

You can't do this automatically in the language. You can do it with Automaper or by manual assignments.
