C#動態(tài)數(shù)組實(shí)用實(shí)例解析
C#動態(tài)數(shù)組(ArrayList )應(yīng)用可以說在C#開發(fā)中是十分常用的,那么具體的實(shí)用實(shí)例是如何實(shí)現(xiàn)的呢?具體的實(shí)現(xiàn)步驟和注意事項(xiàng)是什么呢?
下面就是一個(gè)C#動態(tài)數(shù)組實(shí)例:用綁定一個(gè)DataList的三層代碼
C#動態(tài)數(shù)組之DAL 數(shù)據(jù)訪問層代碼:
- //綁定IDList,顯示所有人員列表
- public DataSet SelectIDListAll()
- {
- string Str = "select p_number,p_name from t_people";
- DataSet ds = new DataSet();
- myCon = new SqlConnection(DAL.DALConfig.ConnectionString);
- try
- {
- SqlDataAdapter mycomm = new SqlDataAdapter(Str,myCon);
- mycomm.Fill(ds,"t_people");
- return ds;
- }
- catch(Exception exc)
- {
- throw exc;
- }
- }
C#動態(tài)數(shù)組之BLL業(yè)務(wù)層代碼:
- //綁定IDList,顯示所有人員列表
- public ArrayList SelectIDListAll()
- {
- DAL.TPeopleDao peopledao = new TPeopleDao();
- DataSet ds = new DataSet();
- ds = peopledao.SelectIDListAll();
- // Creates and initializes a new ArrayList.
- ArrayList myAL = new ArrayList();
- for(int i=0;i<ds.Tables[0].Rows.Count;i++)
- {
- myAL.Add(ds.Tables[0].Rows[i][0].ToString() +
- " " +ds.Tables[0].Rows[i][1].ToString() );
- }
- return myAL;
- }
C#動態(tài)數(shù)組之頁面層代碼:
- //綁定IDList,顯示所有人員列表
- private void SelectIDListAll()
- {
- Lab.BLL.TPeopleBiz peoplebiz = new TPeopleBiz();
- ArrayList myAL = peoplebiz.SelectIDListAll();
- this.P_IDlist.Items.Clear();
- for(int i = 0 ;i<myAL.Count;i++)
- {
- this.P_IDlist.Items.Add(myAL[i]);
- }
- }
C#動態(tài)數(shù)組的應(yīng)用實(shí)例就向你介紹到這里,希望對你了解和學(xué)習(xí)C#動態(tài)數(shù)組有所幫助。
