Question

Is it possible to have a nested class that is public but can only be instantiated by it s parent class e.g.

 public class parent
{
    public class child
    {
        public string someValue;
    }

    public child getChild()
    {
        return new child();
    }
}

举例来说,儿童班级可以通过父母以外的法典进行。我希望外部法典能够看到儿童类型,但无法自行制定。

e.g

var someChild = new parent.child();

Answer 1

Make a public interface.
Make the child class private.
Make the child implement the interface.
Have the getChild method make a new child and return the interface type.

如评论和其他答复所述,你还可以将内层建筑商的准入权改变为内部或私人的,同时让内层本身公开。

Answer 2

界定内部空构者

public class child     
{         
    internal child() {}
    public string someValue;     
}

Answer 3

您可将创作限制在您的构造(儿童班级)的保护水平,以达到<条码>。
