关于线程参数的问题

Question

  public class ThreadMethod   
  {   
        private  int  _param   =   0; 
  
        public  ThreadMethod(int  param )   
        {  
            this._param   =   param;   
        }   
        public  void ThreadRun()   
        {     
            _param ++ ; //可以在线程中改变其值吗？
        }   
  }
  ThreadMethod  method  =  new  ThreadMethod( 1 );   
  Thread t  =  new  Thread(  new ThreadStart( method.ThreadRun) );     
  t.Start();
  通过类来向线程传递参数是一种常见的线程参数传递方法。我看网上例子，传递进去的参数都是读，
  请问可不可以执行写操作？

    class Program
    {
        static void Main(string[] args)
        {
            Card one = new Card();            one.IFlag = 1;
            Thread myThread = new Thread(one.Receive);
            myThread.Start();
            for (int i = 0; i < 102; i++)
            {
                one.IFlag++;
                Thread.Sleep(50);
            }
            Console.ReadKey();
        }
    }    public class Card
    {
        private int iFlag;
        public int IFlag
        {
            get { return iFlag; }
            set { iFlag = value; }
        }        public void Receive()
        {
            while (this.IFlag < 100)
            {
                if (this.IFlag % 5 == 0)
                {
                    this.IFlag += 1;
                    Console.WriteLine(this.IFlag);
                }                Thread.Sleep(50);
            }
            Console.WriteLine("线程结束,按回车键退出.");
        }
    }
