Answer 1

你的Static的obj1和Main里的obj1不是同一个对象

Answer 2

你可以检查当前对象的GetHashCode（）来看是不是同一个对象 同一个对象的GetHashCode（）返回值是相同的
        public void Fun()
        {
            lock (this)
            {
                num = 555;
                Console.WriteLine("线程一锁住this了{0}", num);
                Console.WriteLine("当前对象:{0}",this.GetHashCode());
                Thread.Sleep(6000);
                Console.WriteLine("线程一锁解开this了");
            }
        }
        public void Fun2()
        {
            lock (this)
            {
                num = 999;
                Console.WriteLine("线程二锁住this了{0}", num);
                Console.WriteLine("当前对象:{0}", this.GetHashCode());
                Thread.Sleep(6000);
                Console.WriteLine("线程二锁解开this了");
            }
        }
方法改成这样就很明显了 局部变量和外部Static变量重名的时候 内部对象就覆盖外部对象的名称了 所以此OBJ1非彼OBJ1
