Thread

Thread 정리

Start a thread 

• 일반 사용
• new Thread(Work);
• ThreadStart 사용
• new Thread(new ThreadStart(Work));
• 람다식 사용
• new Thread(() => Work());

Start a thread with parameter

• ParameterizedThreadStart 사용
• new Thread(new ParameterizedThreadStart(WorkWithParam));

Start a thread with return value

• 람다식 이용하여 Return Value 받기 (returnValue는 선언한 object 변수)
• new Thread(() => { returnValue = ReturnableWork(); });
