只需将代码复制到所需窗体下即可。。。。。。。

protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData) //激活回车键
        {
            int WM_KEYDOWN = 256;
            int WM_SYSKEYDOWN = 260;
            if (msg.Msg == WM_KEYDOWN | msg.Msg == WM_SYSKEYDOWN)
            {
                switch (keyData)
                {
                    case Keys.Escape:
                        if(MessageBox.Show("确定要退出么？","信息提示",MessageBoxButtons.YesNo,MessageBoxIcon.Information) == DialogResult.Yes)
                        {
                            this.Close();//csc关闭窗体
                        }                        
                        break;
                    case Keys.Enter:
                        MessageBox.Show("wakaka");
                        break;
                }

            }
