System.Threading.Tasks.Parallel是能够以并行的方式迭代数据集合(实现了IEnumerable<T>的对象),它主要提供2个方法：For()和ForEach()

事例：

using System;
using System.Collections.Generic;
using System.Threading.Tasks;

namespace Net.ConsoleApplication
{
    public class Student
    {
        public string id { get; set; }
        public string name { get; set; }
    }
    public class ParallelDemo
    {
        private List<Student> list = new List<Student>();

        public ParallelDemo()
        {
            for (int i = 0; i < 1000;i++ )
            {
                Student s = new Student();
                s.id = i.ToString("00000");
                s.name = "编号" + s.id;
                list.Add(s);
            }
        }

        public void Do()
        {
            Parallel.ForEach(list, stu => {
                System.Console.WriteLine("id: " + stu.id + ",name: " + stu.name);
            });
        }

    }
}
