從arraylist.Win表單中獲取listbox中所有項目的值

Question

如何使用一個按鈕獲取12個值的數組列表中列表框項的所有值？

SqlDataAdapter sda = new SqlDataAdapter("SELECT PLAYERS.ID, PLAYERS.SURNAME + ', ' + PLAYERS.FIRSTNAME AS PLAYER FROM PLAYERS INNER JOIN TEAMS ON PLAYERS.TEAM_ID = TEAMS.ID WHERE (TEAMS.NAME =oly", con);
DataTable dt = new DataTable();
sda.Fill(dt);

listBox1.DataSource = dt;
listBox1.DisplayMember = "PLAYER";
listBox1.ValueMember = "ID";

Answer 1

如果你希望在列表框'valuemembers'中插入ArrayList，你必須使用循環

ArrayList myAL = new ArrayList();
for(int i = 0; i < dt.Rows.Count; i++)
    myAl.Add(dt.Rows[i]["Name"].ToString());

如果您還想添加ID，可以在此處使用Dictionary ，您可以找到mdsn參考鏈接

Dictionary<string,string> dictionary=new Disctionary<string,string>();
for(int i=0; i <dt.Rows.Count;i++)
  dictionary.Add(dt.Rows[i]["ID"].ToString(),dt.Rows[i]["Name"].ToString());
