在.NET中通过线路移动对象最有效的方法是什么？

using System;
using System.Threading;

class Program
{
    static void Main()
    {
        object obj1 = new object();
        object obj2 = new object();

        // 在多线程环境下移动对象
        Thread thread1 = new Thread(() =>
        {
            object originalObj = Interlocked.Exchange(ref obj1, obj2);
            Console.WriteLine("线程1移动了对象，原始对象引用：" + originalObj);
        });

        Thread thread2 = new Thread(() =>
        {
            object originalObj = Interlocked.Exchange(ref obj1, obj2);
            Console.WriteLine("线程2移动了对象，原始对象引用：" + originalObj);
        });

        thread1.Start();
        thread2.Start();

        thread1.Join();
        thread2.Join();

        Console.WriteLine("最终对象引用：" + obj1);
    }
}
