c#基础知识篇-创建线程的方式

//方式一*(手动创建)
Thread thread = new Thread(() =>
{
    Console.WriteLine("当前线程ID：" + Thread.CurrentThread.ManagedThreadId);
});
thread.Start();

//方式二(Task.Run是Task.Factory.StartNew简写形式)
Task.Run(() => { Console.WriteLine("当前线程ID：" + Thread.CurrentThread.ManagedThreadId); });
Task.Factory.StartNew(() => { Console.WriteLine("当前线程ID：" + Thread.CurrentThread.ManagedThreadId); });

//方式三(线程池创建)
ThreadPool.QueueUserWorkItem((x) =>
{
    Console.WriteLine("当前线程ID：" + Thread.CurrentThread.ManagedThreadId);
});

//方式四(异步BeginInvoke方式在.netcore中不支持)
Action action = () => { Console.WriteLine("当前线程ID：" + Thread.CurrentThread.ManagedThreadId); };
action.BeginInvoke(null,null);

//方式五(并行)
Parallel.For(0, 10, p =>
{
    Thread.Sleep(1000);
    Console.WriteLine("当前线程ID：" + Thread.CurrentThread.ManagedThreadId);
});

Console.WriteLine("当前主线程ID：" + Thread.CurrentThread.ManagedThreadId);
