หากต้องการตรวจสอบว่าเธรดเป็นเธรดพื้นหลังหรือไม่ รหัสมีดังต่อไปนี้ −
ตัวอย่าง
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); } }
ผลลัพธ์
สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -
Current state of Thread = Unstarted ManagedThreadId = 721 Is the Thread a background thread? = False Thread belongs to managed thread pool? = True
ตัวอย่าง
เรามาดูตัวอย่างกัน −
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); } }
ผลลัพธ์
สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -
Current state of Thread = Unstarted ManagedThreadId = 1114 Is the Thread a background thread? = True Thread belongs to managed thread pool? = True
