C# |如何检查线程的当前状态

原文:https://www . geesforgeks . org/c-sharp-如何检查当前线程状态/

线程类负责在多线程编程中创建和管理线程。它提供了一个名为线程状态的属性来检查线程的当前状态。线程的初始状态是未启动状态。

语法:

public ThreadState ThreadState{ get; }

返回值:该属性返回指示当前线程状态的值。

以下程序说明了线程状态属性的使用:

例 1:

// C# program to illustrate the 
// use of ThreadState property
using System;
using System.Threading;

public class GFG {

    // Main Method
    static public void Main()
    {
        Thread thr;

        // Get the reference of main Thread
        // Using CurrentThread property
        thr = Thread.CurrentThread;

        // Display the current state
        // of the main thread
        Console.WriteLine("The name of the current state of the Main " 
                                 + "thread is: {0}", thr.ThreadState);
    }
}

输出:

The name of the current state of the main thread is: Running

例 2:

// C# program to illustrate the 
// use of ThreadState property
using System;
using System.Threading;

public class GFG {

    // Main method
    public static void Main()
    {
        // Creating and initializing threads
        Thread TR1 = new Thread(new ThreadStart(job));
        Thread TR2 = new Thread(new ThreadStart(job));

        Console.WriteLine("ThreadState of TR1 thread"+
                         " is: {0}", TR1.ThreadState);

        Console.WriteLine("ThreadState of TR2 thread"+
                         " is: {0}", TR2.ThreadState);

        // Running state
        TR1.Start();
        Console.WriteLine("ThreadState of TR1 thread "+
                           "is: {0}", TR1.ThreadState);

        TR2.Start();
        Console.WriteLine("ThreadState of TR2 thread"+
                         " is: {0}", TR2.ThreadState);
    }

    // Static method
    public static void job()
    {
        Thread.Sleep(2000);
    }
}

输出:

ThreadState of TR1 thread is: Unstarted
ThreadState of TR2 thread is: Unstarted
ThreadState of TR1 thread is: Running
ThreadState of TR2 thread is: WaitSleepJoin
