SynchronizedList线程安全列表

using System;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;public class SynchronizedList<T>
{private readonly List<T> _list = new List<T>();private readonly object _lockObject = new object();// 添加元素public void Add(T item){lock (_lockObject){_list.Add(item);}}// 移除元素public bool Remove(T item){lock (_lockObject){return _list.Remove(item);}}// 获取元素数量public int Count{get{lock (_lockObject){return _list.Count;}}}// 索引器访问public T this[int index]{get{lock (_lockObject){return _list[index];}}set{lock (_lockObject){_list[index] = value;}}}// 查找元素public bool Contains(T item){lock (_lockObject){return _list.Contains(item);}}// 转换为数组（快照）public T[] ToArray(){lock (_lockObject){return _list.ToArray();}}// 清空列表public void Clear(){lock (_lockObject){_list.Clear();}}
}// 使用示例
class Program
{static void Main(){var syncList = new SynchronizedList<int>();// 多个线程同时操作列表Parallel.For(0, 1000, i =>{syncList.Add(i);});Console.WriteLine($"列表元素数量: {syncList.Count}");Console.WriteLine($"是否包含500: {syncList.Contains(500)}");// 安全地遍历（通过快照）var snapshot = syncList.ToArray();foreach (var item in snapshot){// 安全地处理每个元素
        }}
