c# - 设置隐藏基类的属性

Question

我有以下代码:

public class Ancestor
{
    public string Property {get; protected set;}
}

public class Base : Ancestor
{
    public string Property {get; set;}
}

public class Derived : Base
{
    public Derived(string message)
    {
        //I need both properties to have the message value
    }
}

Ancestor 和 Base 类不是我的代码，我无法更改它们。
有什么办法可以设置Ancestor的属性为message的值吗？
显然简单地做类似下面的事情是行不通的

Ancestor ancestor = this;
ancestor.Property = message

因为 setter 是 protected 。

Answer 1

仅通过反射:

 public class Derived : Base
{
    public Derived(string message)
    {
        Type type = typeof(Ancestor);
        Ancestor a = (Ancestor)this;
        type.GetProperty("Property").SetMethod.Invoke(a, new[] { message });
    }
}
