asp.net 获取动态绑定的CheckBoxList 的选中项

用数组绑定CheckBoxList 然后点击按钮删除选中项，单步调试发现CheckBoxList1.Items.Selected不管是否有选中项都为false，不知道是怎么回事。
protected void Page_Load(object sender, EventArgs e)

{

string[] book = Session["Book"].ToString().Split(',');

this.CheckBoxList1.DataSource = book;

this.CheckBoxList1.DataBind();

}

protected void Button1_Click(object sender, EventArgs e)

{

for (int i = 0; i < CheckBoxList1.Items.Count; i++)

{

if (CheckBoxList1.Items.Selected)

{

CheckBoxList1.Items.RemoveAt(i);

}

}

}

protected void Page_Load(object sender, EventArgs e)
{ if (!IsPostBack)
{
string[] book = Session["Book"].ToString().Split(',');
this.CheckBoxList1.DataSource = book;
this.CheckBoxList1.DataBind();
}}改成
