c#范型与集合

1、要点



2、代码
范型

using System;
using System.Diagnostics;
using System.Collections;
using System.Collections.Generic;

using UnityEngine;

public class FirstSpell : MonoBehaviour
{
    
    
   
   string[] magics = new string[1];

    // Start is called before the first frame update
    void Start()
    {
    
    
        magics[0] = "临";
        magics = AddElement<string>(magics, "兵");
        print(magics[1]);
      
    }

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

    Type[] AddElement<Type>(Type[] array, Type newElement){
    
    
        Type[]newArray = new Type[array.Length + 1];
        for(int i = 0;i< array.Length; i++){
    
    
            newArray[i] = array[i];
        }
         newArray[array.Length] = newElement;
         return newArray;
    }
}

不通过赋值，而是通过引用的形式

using System;
using System.Diagnostics;
using System.Collections;
using System.Collections.Generic;

using UnityEngine;

public class FirstSpell : MonoBehaviour
{
    
    
   
   string[] magics = new string[1];

    // Start is called before the first frame update
    void Start()
    {
    
    
        magics[0] = "临";
        AddElement<string>(ref magics, "兵");
        print(magics[1]);
      
    }

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

    void AddElement<Type>(ref Type[] array, Type newElement){
    
    
        Type[]newArray = new Type[array.Length + 1];
        for(int i = 0;i< array.Length; i++){
    
    
            newArray[i] = array[i];
        }
         newArray[array.Length] = newElement;
         array = newArray;
    }
}

范型集合

using System;
using System.Diagnostics;
using System.Collections;
using System.Collections.Generic;

using UnityEngine;

public class FirstSpell : MonoBehaviour
{
    
    
   //list  范型容器
    List<string> magics = new List<string>();
    //Dictionary 范型字典
    Dictionary<string,string> playerInfo = new Dictionary<string,string>();
    // Start is called before the first frame update
    void Start()
    {
    
    
        //添加新因子or  //插入，清空，截取
        magics.Add("临");

        playerInfo.Add("name","Sophie");
        print(playerInfo["name"]);

        foreach (var item in playerInfo)
        {
    
    
            print(item.Key + " " +item.Value);
        }
    }

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