checkboxlist给label赋值

checkboxlist1有多项，勾选checkboxlist的每一项的值都会在label1上显示出来，当然已勾选的项在点击一次，label上所对应项也会消失，大家帮个忙

aspx

aaaaa

.cs

protected void CheckBoxList1_SelectedIndexChanged ( object sender, EventArgs e )
{
CheckBoxList checkBoxList = sender as CheckBoxList;

string strSelectedTexts = String.Empty;
string strSelectedValues = String.Empty;

foreach ( ListItem item in checkBoxList.Items )
{
if ( item.Selected )
{
strSelectedTexts += (item.Text + "
");
strSelectedValues += (item.Value + "
");
}
}

this.Label1.Text = strSelectedTexts;
}
