本文介绍了在.NET环境下如何实现多线程并发执行的方法，包括无参数、单参数及多参数情况下的线程启动与管理。通过不同类型的示例代码，展示了如何使用ThreadStart和ParameterizedThreadStart等API来创建并控制线程。

多线程并发执行并发函数的时候，当带多个参数的时候，当前.net并不支持

不带参数

并发要执行的函数或对象为run()

            Thread[] threadarray = new Thread[usercount];
            for (int w = 0; w < usercount; w++)
            {
                ThreadStart ts = new ThreadStart(run);
                threadarray[w] = new Thread(ts);
            }
            for (int w = 0; w < usercount; w++)
            {
                threadarray[w].Start();
            }
            for (int w = 0; w < usercount; w++)
            {
                if (threadarray[w].IsAlive == true)
                {
                    threadarray[w].Join();
                }
            }

2.带一个参数

并发要执行的函数或对象为run()，ParameterizedThreadStart 为.NET 2.0新增

            ParameterizedThreadStart [] threadarray = new ParameterizedThreadStart [usercount];
            for (int w = 0; w < usercount; w++)
            {
                ThreadStart ts = new ThreadStart(run);
                threadarray[w] = new ParameterizedThreadStart (ts);
            }
            for (int w = 0; w < usercount; w++)
            {
                threadarray[w].Start(w);
            }
            for (int w = 0; w < usercount; w++)
            {
                if (threadarray[w].IsAlive == true)
                {
                    threadarray[w].Join();
                }
            }

3.带2个以及2个以上参数

并发要执行的类为run(),用构造函数的方式实现多个参数的传递

            Thread[] threadarray = new Thread[usercount];
            for (int w = 0; w < usercount; w++)
            {
                run run1 = new run(s, filename, filecount);
                ThreadStart ts = new ThreadStart(run1.run_update);
                threadarray[w] = new Thread(ts);
            }
            for (int w = 0; w < usercount; w++)
            {
                threadarray[w].Start();
            }
            for (int w = 0; w < usercount; w++)
            {
                if (threadarray[w].IsAlive == true)
                {
                    threadarray[w].Join();
                }
            }
