晚了，兄弟！

前台就是你的页面，文件名后缀为aspx
后台就是你的代码，文件名后缀为aspx.vb或aspx.cs

你下面的/table没有，上面的/title写错了

private void ToRight_Click(object sender, System.EventArgs e)
{
for(int i=0; i<lbox1.Items.Count;i++)
{
ListItem item=lbox1.Items[i];
if(item.Selected)
{
lbox2.Items.Add(item.Text);
lbox1.Items.Remove(item);
}
}
}

private void ToLeft_Click(object sender, System.EventArgs e)
{
for(int i=0; i<lbox2.Items.Count;i++)
{
ListItem item=lbox2.Items[i];
if(item.Selected)
{
lbox1.Items.Add(item.Text);
lbox2.Items.Remove(item);
}
}
}

参考

void Check_Clicked(Object sender, EventArgs e) {
Message.Text="Selected Item(s):" + "<br>" + "<br>";
for (int i=0; i<checkboxlist1.Items.Count; i++) {
if (checkboxlist1.Items[i].Selected)
Message.Text=Message.Text + checkboxlist1.Items[i].Text + "<br>";
}
}
