如何枚举C#中的所有托管线程？

using System;
using System.Threading;

class Program
{
    static void Main(string[] args)
    {
        Thread[] threads = Thread.GetAll();

        Console.WriteLine("托管线程数量：" + threads.Length);

        foreach (Thread thread in threads)
        {
            Console.WriteLine("线程ID：" + thread.ManagedThreadId);
            Console.WriteLine("线程名称：" + thread.Name);
            Console.WriteLine("线程状态：" + thread.ThreadState);
            Console.WriteLine("---------------------------");
        }
    }
}
