c# - 如何获取基类的 "new"参数？

Question

我从这样的无参数构造函数类派生类:

public class Base
{
    public Base(Panel panel1)
    {

    }
}

public class Derived : Base
{
    public Derived() : base(new Panel())
    {
        //How do I use panel1 here?
    }
}

如何在 Derived 中引用 panel1？

(欢迎使用简单的解决方法。)

Adil 的回答假定您可以修改 Base。如果你不能，你可以这样做:

public class Derived : Base
{
    private Panel _panel;

    public Derived() : this(new Panel()) {}

    private Derived(Panel panel1) : base(panel1)
    {
        _panel = panel1;
    }
}
