引入命名空间 using System.Threading;

方式1：手动创建线程

  //开启多线程执行任务                    Thread thread1 = new Thread(a =>                    {                        InsertEs(0, 200000);//执行写入数据区间                    });                    thread1.Start();                    Thread thread2 = new Thread(a =>                    {                        InsertEs(200000, 400000);                    });                    thread2.Start();                    Thread thread3 = new Thread(a =>                    {                        InsertEs(400000, 600000);                    });                    thread3.Start();                    Thread thread4 = new Thread(a =>                    {                        InsertEs(600000, int.MaxValue);                    });                    thread4.Start();                    Thread thread5 = new Thread(a =>                    {                        //调用创建手动录入的用户数据写入索引                        CreateAllDocIndexForManual(client);                    });                    thread5.Start();                    bool status = true;                    while (status)//状态为True说明还有线程没有跑完                    {                        if (thread1.ThreadState == ThreadState.Running                            || thread2.ThreadState == ThreadState.Running                            || thread3.ThreadState == ThreadState.Running                            || thread4.ThreadState == ThreadState.Running                            || thread5.ThreadState == ThreadState.Running)                        {                            status = true;                        }                        else                        {                            status = false;                        }                    }

方式二：线程池

 //创建4个线程同时进行                    var taskArr = new List<Task>();                    taskArr.Add(Task.Run(() =>                    {                        InsertEs(0, 200000);                    }));                    taskArr.Add(Task.Run(() =>                    {                        InsertEs(200000, 400000);                    }));                    taskArr.Add(Task.Run(() =>                    {                        InsertEs(400000, 600000);                    }));                    taskArr.Add(Task.Run(() =>                    {                        InsertEs(600000, int.MaxValue);                    }));                    taskArr.Add(Task.Run(() =>                    {                        //调用创建手动录入的用户数据写入索引                        CreateAllDocIndexForManual(client);                    }));                    Task.WaitAll(taskArr.ToArray(),10000);
