listview多选.只好得到最后一条

listview多选.只能得到最后一条!
绑定id到tag上．

C# code

string[] listArr = new string[] { user, name, pass, smsUState, smsContent, tmpAllToMob.ToString(), sender_name };ListViewItem listLV = new ListViewItem(listArr);listLV.Tag = Convert.ToInt32(dr["Id"]);toplist.Items.Add(listLV);

C# code

private void button1_Click(object sender, EventArgs e){string myid = toplist.SelectedItems[0].Tag.ToString();MessageBox.Show(myid);}

多选了．但是得到的ID只有一个．怎么样才能得到所有选择的tag

[解决办法]
for(int i = 0; i < toplist.SelectedItems.Count; i++)
{
string myid = toplist.SelectedItems[i].Tag.ToString();
}
[解决办法]
forech(ListViewItem listLV in toplist.SelectedItems) 
{
}


[解决办法]
string myid ="";

for(int i = 0; i < toplist.SelectedItems.Count; i++) 
{ 
myid += toplist.SelectedItems[i].Tag.ToString(); 
}

探讨

listview的checkboxes设置为true,选择框为什么不起作用？

[解决办法]

C# code

        private void button1_Click(object sender, EventArgs e)        {            for (int i = 0; i < 3; i++)            {                string[] listArr = new string[] { "user", "name" };                ListViewItem listLV = new ListViewItem(listArr);                listLV.Tag = i;                this.listView1.Items.Add(listLV);            }        }        private void button2_Click(object sender, EventArgs e)        {            for (int i = 0; i < this.listView1.SelectedItems.Count; i++)            {                string myid = this.listView1.SelectedItems[i].Tag.ToString();            }        }
