有免费做门户网站吗百度推广助手怎么用

最近遇到了一个业务场景，需要对List中的数据逐个发起http请求(List中的数据各自独立，对执行顺序无要求)，考虑到可以使用多线程加快处理速度。

封装了如下方法：

/// <summary>/// 多线程处理数据-无返回值/// </summary>/// <param name="list"></param>/// <param name="action">数据处理方法</param>/// <param name="threadCount">开启线程数量</param>/// <param name="waitFlag">是否等待全部结束</param>static void RunTask<T>(List<T> list, Action<T> action, int threadCount = 5, bool waitFlag = true){var queue = new ConcurrentQueue<T>(list);threadCount = Math.Min(threadCount, list.Count);Task[] tasks = new Task[threadCount];for (int i = 0; i < threadCount; i++){tasks[i] = Task.Run(() =>{while (queue.TryDequeue(out T t)){action(t);}});}if (waitFlag){Task.WaitAll(tasks);}}/// <summary>/// 多线程处理数据-有返回值/// </summary>/// <param name="list">待处理数据</param>/// <param name="func">数据处理方法</param>/// <param name="count">开启线程数量</param>static List<TReturn> RunTask<T, TReturn>(List<T> list, Func<T, TReturn> func, int threadCount = 5){var result = new ConcurrentBag<TReturn>();var queue = new ConcurrentQueue<T>(list);threadCount = Math.Min(threadCount, list.Count);var tasks = new Task[threadCount];for (int i = 0; i < threadCount; i++){tasks[i] = Task.Run(() =>{while (queue.TryDequeue(out T t)){result.Add(func(t));}});}Task.WaitAll(tasks);return result.ToList();}

使用示例：

public void DoSingle(User user, string param1, string param2){//HttpHelper.Get("http://xxxx/userid="+user.id);//doSomething();Console.WriteLine(user.Id + "-" + user.Name + "-" + param1 + "-" + param2);}public string DoSingle2(User user, string param1, string param2){//HttpHelper.Get("http://xxxx/userid="+user.id);//doSomething();Console.WriteLine(user.Id + "-" + user.Name + "-" + param1 + "-" + param2);return user.Id + "-666";}public class User{/// <summary>/// id/// </summary>public int Id { get; set; }/// <summary>/// 姓名/// </summary>public string Name { get; set; }}public void Test(){var list = new List<User> {new User { Id = 1, Name = "张三" },new User { Id = 2, Name = "李四" },new User { Id = 3, Name = "王五" }};RunTask(list, t => DoSingle(t, "参数1", "参数2"));var retList = RunTask(list, t => DoSingle2(t, "参数1", "参数2"));}
