Code behind:

DataTable Dt = new DataTable();
   DataTable Dt2 = new DataTable();
       //save
   protected void Button2_Click(object sender, EventArgs e)
   {
       if (TextBox1.Text == string.Empty)
       {
           lblStatus.Text = "Enter value ";
           return;
       }
       if (ViewState["Dt"] == null)
       {
           DataColumn col = new DataColumn("test");
           col.DataType = System.Type.GetType("System.String");
           Dt.Columns.Add(col);
       }
       else
       {
           Dt = (DataTable)ViewState["Dt"];
       }

       DataRow dr =      Dt.NewRow();
       dr[0] = TextBox1.Text;;

       Dt.Rows.Add(dr);
       ListView1.DataSource = Dt;
    ListView1.DataBind();
    ViewState.Add("Dt", Dt);
    lblStatus.Text = "your Item saved ";
    TextBox1.Text = string.Empty;

   }

   protected void ListView1_SelectedIndexChanging(object sender, ListViewSelectEventArgs e)
   {
       ListView1.SelectedIndex = e.NewSelectedIndex;
       lblStatus.Text = "your Item selected ";

       Dt = (DataTable)ViewState["Dt"];
       ListView1.DataSource = Dt;
   }
     //move
   protected void Button1_Click(object sender, EventArgs e)
   {
           //retrive the from datatable Stored in Viewstate
       Dt = (DataTable)ViewState["Dt"];
               //check on the viewstate if not exist i will create strucre for the table
       if (ViewState["Dt2"] == null)
       {
           DataColumn col = new DataColumn("test");
           col.DataType = System.Type.GetType("System.String");
           Dt2.Columns.Add(col);
       }
       else
       {
           Dt2 = (DataTable)ViewState["Dt2"];
       }
           // this can be useful if you can select more than item thorugh checkbox etc .
         //  object[] xx = Dt.Rows[1].ItemArray;
          //foreach (string item in xx)
           //{
           //    string yy = item[0].ToString();
           //}
       //stor the value of selected item in local variable
           string ItemValue = Dt.Rows[ListView1.SelectedIndex][0].ToString();
           //remove the item from Datatable in listview1
           Dt.Rows.RemoveAt(ListView1.SelectedIndex);
       //create new row in 2th datatable    , storeing the value
           DataRow dr2 = Dt2.NewRow();
           dr2[0] = ItemValue;

可能对您有帮助..
for(int i = 0; i< = ListBox1.Items.Count-1; i ++)
{
ListBox2.Items.Add(ListBox1.Items [i]);

May this help you..
for (int i = 0; i <= ListBox1.Items.Count - 1; i++)
{
ListBox2.Items.Add(ListBox1.Items[i]);
