用ShowDialog出现的问题,同窗体使用快键的问题

Question

private void ok_Click(object sender, EventArgs e) 
        {             this.DialogResult = DialogResult.No; 
            //this.Close(); 
        }

Answer 1

 if ((Keys)e.KeyChar == Keys.Enter)//这里我怎样做用CTRL +F键来替代用ENTER键,我试下了用Keys.ControlKey不行 
            { 
                SearchSode sc = new SearchSode(); 
                sc.ShowDialog(); //这里执行了两次ShowDialog
                if (sc.ShowDialog() == DialogResult.OK) 
                { 
                   MessageBox.Show("ok"); 
                } 
    }
