用linq: 

ListViewItem li = ListViewUser.Items.Cast().First(x => x.Text == "1005" && x.SubItems["city"].Text == "北京");
string val = li.SubItems["city"].Text;

也可以是：   
 ListViewItem liv = listViewAlarm.Items.Cast().First(x => x.SubItems[0].Text == strID);          
            int index = liv.Index;
            listViewAlarm.Items[index].SubItems[1].Text = "something";
