C#/.NET多线程实战——自定义程序运行的线程，并保持线程数不变

1.无参数

int asynLimit = 15;//异步线程限制
List<Task> taskList = new List<Task>();
TaskFactory taskFactory = new TaskFactory();
foreach (Category category in categoryList)
{
    ISearch searcher = new CommoditySearch(category);
    //searcher.Crawler();
    taskList.Add(taskFactory.StartNew(searcher.Crawler));
    if (taskList.Count > asynLimit )
    {
        taskList = taskList.Where(t => !t.IsCompleted && !t.IsCanceled && !t.IsFaulted).ToList();
        Task.WaitAny(taskList.ToArray());
    }
}
