listview和简单的记事本操作

listview：

                //每一列的列名用Columns集合添加
                ListViewItem lv = new ListViewItem();
                lv.Text = s.Code.ToString();//每一行的第一列的项通过text添加
                lv.SubItems.Add(s.Name);//每一行的其他列的项通过SubItems集合添加
                lv.SubItems.Add(s.Sex);
                lv.SubItems.Add(s.Birthday.ToString("yyyy年MM月dd日"));
                lv.SubItems.Add(s.Score.ToString("#.##"));
                listView1.Items.Add(lv);//每一行用Items集合添加，添加的数据是上面每一项的值

简单的记事本操作：

        private void 退出XToolStripMenuItem_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void 撤消UToolStripMenuItem_Click(object sender, EventArgs e)
        {
            textBox1.Undo();
        }

        private void 剪切TToolStripMenuItem_Click(object sender, EventArgs e)
        {
            textBox1.Cut();
        }

        private void 复制CToolStripMenuItem_Click(object sender, EventArgs e)
        {
            textBox1.Copy();
        }

        private void 粘贴PToolStripMenuItem_Click(object sender, EventArgs e)
        {
            textBox1.Paste();
        }

        private void 全选AToolStripMenuItem_Click(object sender, EventArgs e)
        {
            textBox1.SelectAll();
        }
