一：基础类型集合排序

/// <summary>
/// 排序
/// </summary>
/// <param name="isReverse">顺序是否取反</param>
public static void Sort<T>(this IList<T> array, bool isReverse = false)where T : IComparable
{var count = array.Count;for (int i = 0; i < count; i++){for (int j = 0; j < count; j++){var k = j + 1;if (k >= count)break;if (!isReverse){if (array[j].CompareTo(array[k]) == 1)(array[j], array[k]) = (array[k], array[j]);}else{if (array[j].CompareTo(array[k]) == -1)(array[j], array[k]) = (array[k], array[j]);}}}
}

测试：

if (Input.GetKeyDown(KeyCode.Space))
{// 字符串数组var strArray = new[] {"8", "1", "J", "D","A", "B1"};strArray.Sort(true);string str0 = "";for (int i = 0; i < strArray.Length; i++){str0 += strArray[i] + ((i + 1 < strArray.Length) ? "、" : "");}Debug.LogError(str0);// int数组var intArray = new[] {8, 1, 10, 5, 9, 7};intArray.Sort();string str1 = "";for (int i = 0; i < intArray.Length; i++){str1 += intArray[i] + ((i + 1 < intArray.Length) ? "、" : "");}Debug.LogError(str1);
}

二：排序扩展（根据某个类型排序）

[System.Runtime.InteropServices.ComVisible(true)]
public interface IComparableByEnum : IComparable
{int CompareTo(Enum sortEnum, object compareObj);
}/// <summary>
/// 排序
/// </summary>
/// <param name="sortEnum">依据什么类型排序</param>
/// <param name="isReverse">顺序是否取反</param>
public static void Sort<T>(this IList<T> array, Enum sortEnum, bool isReverse = false)where T : IComparableByEnum
{var count = array.Count;for (int i = 0; i < count; i++){for (int j = 0; j < count; j++){var k = j + 1;if (k >= count)break;if (!isReverse){if (array[j].CompareTo(sortEnum, array[k]) == 1)(array[j], array[k]) = (array[k], array[j]);}else{if (array[j].CompareTo(sortEnum, array[k]) == -1)(array[j], array[k]) = (array[k], array[j]);}}}
}

public enum SortType
{Id,Name,
}public class MyClass : IComparableByEnum
{public int id;public string name;public MyClass(int _id, string _name){id = _id;name = _name;}public int CompareTo(object obj){return CompareTo(MySortType.Id, obj);}public int CompareTo(Enum sortEnum, object compareObj){if (!(sortEnum is SortType sortType))return -1;if (!(compareObj is MyClass value))throw new ArgumentException($"参数不是{nameof(MyClass)}类型");return sortType switch{SortType.Id => id.CompareTo(value.id),SortType.Name => string.Compare(name, value.name, StringComparison.CurrentCulture),_ => throw new ArgumentException($"排序类型出错{sortType}")};}
}

测试：

private void Update()
{if (Input.GetKeyDown(KeyCode.Space)){var list = new List<MyClass>(){new MyClass(5,"Zz"),new MyClass(86,"C"),new MyClass(1,"Aa"),new MyClass(0,"Bb"),new MyClass(20,"Tt"),};list.Sort(SortType.Id);string str0 = "";for (int i = 0; i < list.Count; i++){str0 += $"{list[i].id};{list[i].name}" + (i + 1 < list.Count? "、" : "");}Debug.LogError(str0);list.Sort(SortType.Name);string str1 = "";for (int i = 0; i < list.Count; i++){str1 += $"{list[i].name};{list[i].id}" + (i + 1 < list.Count? "、" : "");}Debug.LogError(str1);}
}
