ASP.NET 使用线程异步执行代码块

第一种：Thread

new Thread(() =>
{
  //执行代码块
}).Start();

// GET: api/BackgroundWorker
[HttpGet]
[Route("start")]
public void StartWorker()
{
  
  //写法1：
  //Thread thread = new Thread(this.DoBackGroundWork);
  
  //写法2：
  Thread thread = new Thread(() => DoBackGroundWork());
  thread.Start();
  
  //写法3：
  new Thread(() =>
  {
    //执行代码块
    //...
  }).Start();

}

public void DoBackGroundWork()
{
  //执行代码块
  //...
}

第二种：BackgroundWorker

BackgroundWorker barInvoker = new BackgroundWorker();
barInvoker.DoWork += delegate
{
  //执行代码块
};
barInvoker.RunWorkerAsync();
