public class fact
    {
        private bool _Clicked;
        public bool clicked
        {
            get { return _Clicked; }
            set
            {
                _Clicked = value;}}private string _GetText;
        public string getText
        {
            get
            {

                if (_Clicked)
                {
                    _GetText = "回答正确";
                }
                else
                {
                    _GetText = "回答错误";
                }

                return _GetText;
            }

        }
       
       
    }



 

C# code

  public partial class Form3 : Form    {        BindingSource bindingSource1 = new BindingSource();        public Form3()        {            InitializeComponent();                   }        private void button1_Click(object sender, EventArgs e)        {            fact _fact=new fact();            _fact.clicked=true;            bindingSource1.Add(_fact);            label1.DataBindings.Add("Text", bindingSource1, "getText");        }    }
