Detailed introduction to the difference between C# threads and thread pools

Creation of thread: (Unlike java, there is no need to inherit the Thread class)

TcpClient tc = tListener.AcceptTcpClient();                    
CThreadServer ctserver = new CThreadServer(tc);                    
Thread t = new Thread(new ThreadStart(ctserver.AcceptImageFile));                    
t.IsBackground = true;                    
t.Start();

Creation of thread pool

TcpClient tc = tListener.AcceptTcpClient();                    
CThreadServer ctserver = new CThreadServer(tc);                    
//Thread t = new Thread(new ThreadStart(ctserver.AcceptImageFile));                    
//t.IsBackground = true;                    
//t.Start();                    
ThreadPool.QueueUserWorkItem(new WaitCallback(ctserver.AcceptImageFile));

But here AcceptImageFile and thread creation The AcceptImageFile in is different

In thread creation, it is AcceptImageFile();

In thread pool creation, it is AcceptImageFile(Object o);The Object o here is Must join.
