cs项目中窗体间方法的传递

public partial class Form1 : Form
    {
        //声明委托,用于窗体间方法的传递
        public delegate void DelegateLoadview();

        public Form1()
        {
            InitializeComponent();
        } 
      //窗体加载时
      private void Form1_Load(object sender, EventArgs e)
        {
            LoadGridview();
        }

        //绑定数据
        private void LoadGridview()
        {
            List<ASRS_User> list = bll.Sel();
            this.dataGridView1.DataSource = list;
        }


        //添加产品
        private void btnAdd_Click(object sender, EventArgs e)
        {
            DelegateLoadview dld = new DelegateLoadview(LoadGridview);
            FAdd fd = new FAdd(dld);
            fd.ShowDialog();
        }
       }

窗体2中的代码

 public partial class FAdd : Form
    {
        private Form1.DelegateLoadview dld;

        public FAdd()
        {
            InitializeComponent();
        }

        public FAdd(Form1.DelegateLoadview dld)
            : this()
        {
            // TODO: Complete member initialization
            this.dld = dld;
        }

        //确定
        private void button1_Click(object sender, EventArgs e)
        {
            string num = txtNum.Text.Trim();
            if (num == "")
            {
                MessageBox.Show("请输入");
            }
            else
            {
                //刷新数据
                dld();
            }

        }
    }

完成form1窗体中方法的调用了
