继承窗体监听键盘事件，在子窗体中处理键盘事件

public partial class BaseForm : Form
    {
        public BaseForm()
        {
            InitializeComponent();
        }

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
            if ((keyData & Keys.Enter) == Keys.Enter)
            {
                if (OnEnter("13")) return true;
            }
            return base.ProcessCmdKey(ref msg, keyData);

        }
        protected virtual bool OnEnter(string type)
        {
            return true;
        }
    }

子窗体

public partial class Form1 : BaseForm
    {
        public Form1()
        {
            InitializeComponent();
        }


        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {

        }

        private void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {

        }

        protected override bool OnEnter(string key)
        {
            MessageBox.Show(key);
            return true;
        }
    }
