c#之List乱序方法

using System;
using System.Collections.Generic;

public static class ListExtensions
{
    public static void Shuffle<T>(this List<T> list)
    {
        int n = list.Count;
        Random rnd = new Random();
        for (int i = 0; i < n; i++)
        {
            int r = i + rnd.Next(n - i);
            (list[r], list[i]) = (list[i], list[r]);
        }
    }
    
    public static void SortRandom<T>(this T[] array){
        int r;
        for(int i=array.Length-1;i>0;i--){
            r = UnityEngine.Random.Range(0, i);
            (array[r], array[i]) = (array[i], array[r]);
        }
    }
    
    public static void SortRandom<T>(this List<T> list){
        int r;
        for(int i=list.Count-1;i>0;i--){
            r = UnityEngine.Random.Range(0, i);
            (list[r], list[i]) = (list[i], list[r]);
        }
    }
}

调用方式

var list2 = new List<int>();
for (var i = 0; i < 10; i++)
{
    list2.Add(i);
}

//list2.Shuffle<int>();
list2.SortRandom<int>();
foreach (var value in list2)
{
    Debug.Log($"{value}");
}
