C#多线程传递参数及任务用法示例

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading;namespace ConsoleSample{  class Program  {    static void Main(string[] args)    {      Console.WriteLine("这是主线程");      DateTime dtStart = DateTime.Now;      for (int i = 0; i < 100; i++)      {        Student s = new Student();        s.name = "张三" + i;        s.sex = "男";        s.age = 28;        Thread t = new Thread(ThreadWithParas);        t.Start(s); //要给线程传递数据，需某个存储数据的类或结构      }      DateTime dtEnd = DateTime.Now;      TimeSpan span = (TimeSpan)(dtEnd - dtStart);      Console.ReadLine();      Console.WriteLine("运行的时间 " + span.Milliseconds);      Console.ReadLine();    }    static void ThreadWithParas(object o)    {      Student s = o as Student;      Console.WriteLine("这是分线程" + Thread.CurrentThread.ManagedThreadId + " " + s.name + "---" + s.sex + "---" + s.age);    }  }  public class Student  {    public string name;    public string sex;    public int age;  }}
