Để kiểm tra xem một chuỗi có còn tồn tại hay không, mã như sau -
Ví dụ
using System; using System.Threading; public class Demo { public static void Main() { Thread thread = new Thread(new ThreadStart(demo1)); thread = Thread.CurrentThread; Console.WriteLine("Is the thread alive? = "+thread.IsAlive); ThreadPool.QueueUserWorkItem(new WaitCallback(demo2)); Console.WriteLine("Current state of Thread = "+thread.ThreadState); Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId); thread.IsBackground = true; Console.WriteLine("Is the Thread a background thread? = "+thread.IsBackground); } public static void demo1() { Thread.Sleep(2000); } public static void demo2(object stateInfo) { Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread); } }
Đầu ra
Điều này sẽ tạo ra kết quả sau -
Is the thread alive? = True Current state of Thread = Running ManagedThreadId = 775 Is the Thread a background thread? = True Thread belongs to managed thread pool? = True
Ví dụ
Bây giờ chúng ta hãy xem một ví dụ khác -
using System; using System.Threading; public class Demo { public static void Main() { Thread thread = new Thread(new ThreadStart(demo)); thread.Start(); Console.WriteLine("Is the Thread alive? "+thread.IsAlive); } public static void demo() { Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread); } }
Đầu ra
Điều này sẽ tạo ra kết quả sau -
Is the Thread alive? True Thread belongs to managed thread pool? = False
