Để kiểm tra xem một chuỗi có phải là một chuỗi nền 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)); ThreadPool.QueueUserWorkItem(new WaitCallback(demo2)); Console.WriteLine("Current state of Thread = "+thread.ThreadState); Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId); Console.WriteLine("Is the Thread a background thread? = "+Thread.CurrentThread.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 -
Current state of Thread = Unstarted ManagedThreadId = 721 Is the Thread a background thread? = False Thread belongs to managed thread pool? = True
Ví dụ
Hãy để chúng tôi xem một ví dụ khác -
using System; using System.Threading; public class Demo { public static void Main() { Thread thread = new Thread(new ThreadStart(demo1)); 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 -
Current state of Thread = Unstarted ManagedThreadId = 1114 Is the Thread a background thread? = True Thread belongs to managed thread pool? = True
