C＃中的继承问题：CS7036

Question

由于某种原因，我在构造方法“修改后的ercise”中遇到错误 CS7036：没有任何参数对应于所需的正式参数name of coresoce.cortion.corcise（string，int，int，int，string，string，string []，dictionary＆lt; string，bool＆gt;）< /代码> 我添加了父级和子类练习和修改exercise。

using System;
using System.Collections.Generic;
using System.Text;

namespace Trainer_App
{
    internal class ModifiedExercise : Exercise 
    {
        private Exercise regular_exercise;
        public ModifiedExercise(Exercise regular_exercise,
                                string name,
                                int min_num_balls,
                                int participants_num,
                                string court_type,
                                string[] accessories,
                                Dictionary<string, bool> exerciseTypes)
        {
            this.regular_exercise = regular_exercise;
            this.id = Exercise.id_counter;
            Exercise.id_counter++;
            this.name = name;
            this.min_num_balls = min_num_balls;
            this.participants_num = participants_num;
            this.court_type = court_type;
            this.accessories = accessories;
            this.exerciseTypes = exerciseTypes;

        }
    }
}

Answer 1

默认情况下，构造仪有效地调用：base（）在其基本类型上

您有两个选项：

1. 到基本类型
2. 添加受保护的练习（）{} {}无参数构造函数 ：base（...）明确指定要传递的值，在基本构造函数上的位置

：2是通常的方法，用于减少重复。这也允许字段保留私有。
