1.自定义Worker字段类

    public class SelectWorker    {        public int WorkerID;        public string WkName;    }

2.定义全局变量

        List<SelectWorker> wkList0 = new List<SelectWorker>();        List<SelectWorker> wkList1 = new List<SelectWorker>();        List<SelectWorker> wkList2 = new List<SelectWorker>();         int selRow0 = -1, selRow1 = -1;        int selTRow0 = -1, selTRow1 = -1;

3.初始化listView函数

        void InitListView12()        {            listView1.View = View.Details;            ColumnHeader ch1 = new ColumnHeader();            ColumnHeader ch2 = new ColumnHeader();            ch1.Text = "编码";            ch2.Text = "姓名";            listView1.Columns.Add(ch1);            listView1.Columns.Add(ch2);            listView2.View = View.Details;            ColumnHeader ch4 = new ColumnHeader();            ColumnHeader ch5 = new ColumnHeader();            ch4.Text = "编码";            ch5.Text = "姓名";            listView2.Columns.Add(ch4);            listView2.Columns.Add(ch5);        }

4.窗体加载事件

        private void Form1_Load(object sender, EventArgs e)        {            string SQL;            InitListView12();            MyDBase DB = new MyDBase(DBUser.sServer, DBUser.sDBName, DBUser.sUser, DBUser.sPasswd);            SQL = "SELECT workerID,wkName FROM worker order by workerID";            SqlDataReader RD0 = DB.DBDataReader(SQL);            while (RD0.Read())            {                SelectWorker SW = new SelectWorker();                SW.WorkerID = int.Parse(RD0["WorkerID"].ToString());                SW.WkName = RD0["WkName"].ToString();                wkList0.Add(SW);                wkList2.Add(SW);                  ListViewItem lvi = new ListViewItem();                lvi.Text = SW.WorkerID;                lvi.SubItems.Add(SW.WkName);                listView1.Items.Add(lvi);            }            RD0.Close();            DB.DBClose();        }

5.向listView1和listView2中加减记录

        void LoadInListView12()        {            int i, n;            listView1.Items.Clear();            listView2.Items.Clear();            InitListView12();            n = wkList0.Count;            for (i = 0; i < n; i++)            {                ListViewItem lvi = new ListViewItem();                lvi.Text=wkList0[i].WorkerID.ToString();                lvi.SubItems.Add(wkList0[i].WkName);                listView1.Items.Add(lvi);            }            n = wkList1.Count;            for (i = 0; i < n; i++)            {                   ListViewItem lvi = new ListViewItem();                lvi.Text=wkList0[i].WorkerID.ToString();                lvi.SubItems.Add(wkList0[i].WkName);                listView1.Items.Add(lvi);             }         }

6.listView1和listView的选择事件

        private void listView1_SelectedIndexChanged(object sender, EventArgs e)        {            int length = listView1.SelectedItems.Count;            for (int i = 0; i < length; i++)                selRow0 = listView1.SelectedItems[i].Index;         }        private void listView2_SelectedIndexChanged(object sender, EventArgs e)        {            int length = listView2.SelectedItems.Count;            for (int i = 0; i < length; i++)                selRow1 = listView2.SelectedItems[i].Index;         }

7.添加员工

        private void button1_Click(object sender, EventArgs e)        {            if (selRow0 == -1)            {                MessageBox.Show("请选择一个职工", "没有选择职工提示", MessageBoxButtons.OK, MessageBoxIcon.Information);                return;            }            SelectWorker SelWK = new SelectWorker();            SelWK = wkList0[selRow0];            wkList0.Remove(SelWK);            wkList1.Add(SelWK);            LoadInListView12();            selRow0 = -1;         }

8.减掉员工

        private void button2_Click(object sender, EventArgs e)        {            if (selRow1 == -1)            {                MessageBox.Show("请选择一个职工", "没有选择职工提示", MessageBoxButtons.OK, MessageBoxIcon.Information);                return;            }            SelectWorker SelWK = new SelectWorker();            SelWK = wkList1[selRow1];            wkList1.Remove(SelWK);            wkList0.Add(SelWK);            LoadInListView12();            selRow1 = -1;         }
