vs2005的代码    public class fact
    {
        private int _lv=0;
        public int lv
        {
            get { return _lv; }
            set
            {
                _lv = value;
            }
        }        private string _infor;
        public string infor
        {
            get
            {                if (_lv==1)
                {
                    _infor = "无限制";
                }
                if (_lv==2)
                { _infor = "有限制";
                }
                if (_lv==0)
                {
                    _infor = String.Empty; //不知道你的具体要求，我这里设置一个Empty为默认值
                }                return _infor;
            }        }
        
        
    }
   public partial class Form3 : Form
    {
        BindingSource bindingSource1 = new BindingSource();
        fact _fact = new fact();
        public Form3()
        {
            InitializeComponent();
            
           
        }        private void button1_Click(object sender, EventArgs e)
        {            
            ((fact)bindingSource1.Current).lv = 1;
            bindingSource1.ResetCurrentItem();
            
            
            
        }        private void Form3_Load(object sender, EventArgs e)
        {
            bindingSource1.Add(_fact);
            textBox1.DataBindings.Add("Text", bindingSource1, "infor");
           
        }        private void button2_Click(object sender, EventArgs e)
        {
            ((fact)bindingSource1.Current).lv = 2;
            bindingSource1.ResetCurrentItem();        }
    }

class Program

        static void Main(string[] args)
        {
            System.Windows.Forms.Form form = new System.Windows.Forms.Form();

            form.Controls.Add(btn1);
            form.Controls.Add(btn2);            tb.Left = 0;
            tb.Top = 0;
            btn1.Click += delegate(object sender,EventArgs e) 
            {
                manager m = new manager(1);
                tb.Text = m.infor;
            };
            btn1.Top = 30;

        public class manager
