C#运算符重载与运算符继承

```csharp
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{
    MagicApprentice p1 = new(1), p2 = new(2);
    Apprentice p3 = new();

public void Start()
    {
        p3=p1 + p2;
        print(p3.age);
    }
}
class Apprentice
{
    public int age;
    public string name;
    public Apprentice() { }
    public Apprentice(int age)
    {
        this.age = age;
    }
    public Apprentice(string name)
    {
        this.name = name;
    }
    public Apprentice(string name,int age)
    {
        this.name = name;
        this.age = age;
    }
    public void TellName() { Debug.Log("I'm " + name); }
    public static Apprentice operator +(Apprentice a1, Apprentice a2)
    {
        return new Apprentice(a1.age + a2.age);
    }
}
interface Magic
{
    void Ino();
}

class MagicApprentice : Apprentice,Magic
{
    
    public void Ino()
    {
        Debug.Log("Master Spark!");
    }
    public MagicApprentice() { }
    public MagicApprentice(int age)
    {
        this.age = age;
    }
    public MagicApprentice(string name)
    {
        this.name = name;
    }
    public MagicApprentice(string name, int age)
    {
        this.name = name;
        this.age = age;
    }
}
```
以上，注意返回值即可。
