Answer 1

  private void Form1_Load(object sender, EventArgs e)
        {
            SqlConnection conn = new SqlConnection("Data Source=192.168.1.41;Initial Catalog=LCEcom_DataBASE;User ID=data_admin;Password=jbvB0X");
            if (conn.State == ConnectionState.Closed)
            {
                conn.Open();
            }
            SqlCommand command = new SqlCommand("select * from ImageType_TB",conn);
            SqlDataReader sr = command.ExecuteReader();
            DataTable dt = new DataTable();
            if (sr.HasRows)
            {
                dt.Load(sr);
            }
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                listView1.Items.Add(dt.Rows[i]["ColumnnameName"].ToString());
            }
            if (listView1.Items.Count > 0)
            {
                label1.Text = listView1.Items[0].Text;
            }            
        }        private void listView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            int c = this.listView1.SelectedItems.Count;
            this.label1.Text = this.listView1.FocusedItem.SubItems[0].Text;
        }

Answer 2

SelectedIndexChanged事件  

Answer 3

if (listView1.Items.Count > 0)
            {
                label1.Text = listView1.Items[0].Text;
            }
然后用SelectedIndexChanged事件 
private void listView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            this.label1.Text = listView1.SelectedItems.ToString();
        }
 我没测试，LZ可以试试
