C#静态类的扩展应用

下边是我学了静态类之后的一些对静态类的一些进阶使用

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


static class Tools
{
    
    

    public static void SpeakValue(this int value)
    {
    
    
        Debug.Log("我为int拓展的方法" + value);
    }

    public static void SpeakStringInfo(this string str,string str2,string str3)
    {
    
    
        Debug.Log("唐老师为string拓展的方法");
        Debug.Log("调用方法的对象" + str);
        Debug.Log("穿的参数是" + str2 + str3);
    }

    public static void Fun2(this Test t)
    {
    
    
        Debug.Log("为test拓展的方法");
    }
}

class Test
{
    
    
    public int i = 10;
    public void Fun1()
    {
    
    
        Debug.Log("1234");
    }

    public void Fun2()
    {
    
    
        Debug.Log("456");
    }


}


public class MyTestFavourite : MonoBehaviour
{
    
    
   

    // Start is called before the first frame update
    void Start()
    {
    
    
        //int i = 10;
        // i.SpeakValue();

        //string str = "0000";
        //str.SpeakStringInfo("222", "333");

        Test t = new Test();
        t.Fun2();

    }

    // Update is called once per frame
    void Update()
    {
    
    
        
    }
}
