{public abstract class Father
    {public string name;
        public Father(string name)
        {this.name = name;
            Debug.Log("father:" + this.name);
        }
    }

    public class Children : Father
    {public string name;
        public Children(string name) : base(name)
        {this.name = "chilid-" + name;
            Debug.Log("chilid:" + this.name);
        }
    }


    public class UnitTest
    {public static void Start()
        {Father c = new Children("kaka");
            test(c);
        }

        public static void test(Father f)
        {Debug.Log(f.name);
        }
    }
}

子类不写同名字段name，输出子类的namechile-kaka

using UnityEngine;

namespace Tests.mapilot
{public abstract class Father
    {public string name;
        public Father(string name)
        {this.name = name;
            Debug.Log("father:" + this.name);
        }
    }

    public class Children : Father
    {public Children(string name) : base(name)
        {this.name = "chilid-" + name;
            Debug.Log("chilid:" + this.name);
        }
    }


    public class UnitTest
    {public static void Start()
        {Father c = new Children("kaka");
            test(c);
        }
