Asp.Net(C#)+Sql Server三层架构下数据存取方案(三)

一、　数据层类：using System;using System.Collections;using System.Data;using System.Data.SqlClient;using Town.Data;using Town.Log; namespace Town.Com{ /// <summary> /// 功能：积分设置集合类 /// 作者：Rexsp /// 创建日期：2004-01-14 /// 修改者： /// 修改日期： /// </summary> public class ScoreSettingCollection { #region 私有成员 private ArrayList members; #endregion #region 构造函数 /// <summary> /// 构造函数 /// </summary> public ScoreSettingCollection() { } #endregion #region 公共属性 /// <summary> /// Operation对象的个数 /// </summary> public int Count { get { if( members != null ) return members.Count; else return 0; } } #endregion #region 索引 /// <summary> /// 索引 /// </summary> public ScoreSetting this[int index] { get { if ( members != null ) return (ScoreSetting)( members[index] ); else return null; } } #endregion #region 私有方法 /// <summary> /// 添加Operation到OperationCollection集合 /// </summary> private void Add(ScoreSetting scoreSetting) { if ( members == null ) members = new ArrayList(); members.Add( scoreSetting ); } #endregion
