C＃|检查线程是否属于托管线程池

Thread类负责在多线程编程中创建和管理线程。它提供了一个称为IsThreadPoolThread的属性，以检查线程是否属于托管线程池。

句法：

public bool IsThreadPoolThread { get; }

返回值：如果给定线程属于托管线程池，则此属性返回true。否则，返回false 。此属性的返回类型为System.Boolean 。

下面的程序说明了IsThreadPoolThread属性的用法：

范例1：

// C# program to illustrate the use 
// of IsThreadPoolThread  property
using System;
using System.Threading;
  
class GFG {
  
    // Main Method
    static public void Main()
    {
        Thread T;
  
        // Get the reference of main Thread
        // Using CurrentThread property
        T = Thread.CurrentThread;
  
        // Check if the main thread belongs to
        // the managed thread pool or not
        // Using IsThreadPoolThread  property
        Console.WriteLine("Is main thread belongs to Thread"+
                      " pool? : {0} ", T.IsThreadPoolThread);
    }
}

输出：

Is main thread belongs to Thread pool? : False 

范例2：

// C# program to illustrate the use
//  of IsThreadPoolThread  property
using System;
using System.Threading;
  
class GFG {
  
    // Main method
    public static void Main()
    {
  
        // Creating and initializing threads
        Thread TR1 = new Thread(new ThreadStart(job));
        ThreadPool.QueueUserWorkItem(new WaitCallback(job1));
        TR1.Start();
    }
  
    // Static methods
    public static void job()
    {
        Console.WriteLine("Is thread 1 belongs to thread pool: {0}",
                           Thread.CurrentThread.IsThreadPoolThread);
    }
  
    public static void job1(object stateInfo)
    {
        Console.WriteLine("Is thread 2 belongs to thread pool: {0}",
                           Thread.CurrentThread.IsThreadPoolThread);
    }
}

输出：

Is thread 1 belongs to thread pool: False
Is thread 2 belongs to thread pool: True
