实际显示代码如下：

public partial class Form1 : Form
    {
        //用结构体来作数据集
        private struct  A
        {

            }
            public override string ToString()
            {
                return name;
            }
        }
        //
        public Form1()
        {
            InitializeComponent();
        }

        private void rbStudent_CheckedChanged(object sender, EventArgs e)
        {
            this.clbStudent.Items.Clear();
            //string sno = System.Guid.NewGuid().ToString();
            //取全球唯一的字符码
            this.clbStudent.Items.Add(new A("增加学生", System.Guid.NewGuid().ToString()));
            this.clbStudent.Items.Add(new A("增加学生", System.Guid.NewGuid().ToString()));
            this.clbStudent.Items.Add(new A("增加学生", System.Guid.NewGuid().ToString()));
        }

        private void btnSave_Click(object sender, EventArgs e)
        {
            this.tbxStudent.Text = "&&";
            foreach (object o in this.clbStudent.CheckedItems)
            {
                this.tbxStudent.Text += "/n" + ((A)o).id;
            }
            this.tbxStudent.Text = this.tbxStudent.Text.Replace("&&/n","/n");
