C＃|获取当前托管线程的唯一标识符

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ManagedThreadId的属性来检查当前托管线程的唯一标识符。换句话说，线程的ManagedThreadId属性的值在其进程内唯一定义该线程。 ManagedThreadId属性的值不会随时间变化。

句法：

public int ManagedThreadId { get; }

返回值：该属性返回一个值，该值指示此托管线程的唯一标识符。此属性的返回类型为System.Int32 。

范例1：

// C# program to illustrate the 
// use of ManagedThreadId property
using System;
using System.Threading;
  
public class GFG {
  
    // Main Method
    static public void Main()
    {
        Thread T;
  
        // Get the reference of main Thread
        // Using CurrentThread property
        T = Thread.CurrentThread;
  
        // Display the unique id of the main 
        // thread Using ManagedThreadId property
        Console.WriteLine("The unique id of the main "+
                 "thread is: {0} ", T.ManagedThreadId);
    }
}

输出：

The unique id of the main thread is: 1 

范例2：

// C# program to illustrate the 
// use of ManagedThreadId property
using System;
using System.Threading;
  
public class GFG {
  
    // Main method
    public static void Main()
    {
        // Creating and initializing threads
        Thread thr1 = new Thread(new ThreadStart(job));
        Thread thr2 = new Thread(new ThreadStart(job));
        Thread thr3 = new Thread(new ThreadStart(job));
  
        Console.WriteLine("ManagedThreadId of thread 1 "+
                        "is: {0}", thr1.ManagedThreadId);
  
        Console.WriteLine("ManagedThreadId of thread 2 "+
                        "is: {0}", thr2.ManagedThreadId);
  
        Console.WriteLine("ManagedThreadId of thread 3 "+
                        "is: {0}", thr3.ManagedThreadId);
  
        // Running state
        thr1.Start();
        thr2.Start();
        thr3.Start();
    }
  
    // Static method
    public static void job()
    {
        Thread.Sleep(2000);
    }
}

输出：

ManagedThreadId of thread 1 is: 3
ManagedThreadId of thread 2 is: 4
ManagedThreadId of thread 3 is: 5
