Answer 3

给你一个帮助文件，需要使用的时候直接调用，最后面是调用方法：
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Configuration;
using System.Data.SqlClient;
using VtechDAL;
//using DBUtility;namespace MyDAL
{
    public class DBHelper
    {
               //string strAppConfigFile = ConfigurationManager.AppSettings["DataBaseType"].ToString();        //Helper _helper = new Helper();
        //public  Helper GetHelper()
        //{            
        //    switch (strAppConfigFile)
        //    {
        //        case "System.Data.OracleClient":
        //            _helper.DatabaseType = Helper.DatabaseTypes.Oracle;
        //            break;
        //        case "MySql.Data.MySqlClient":
        //            _helper.DatabaseType = Helper.DatabaseTypes.MySql;
        //            break;
        //        case "System.Data.OleDb":
        //            _helper.DatabaseType = Helper.DatabaseTypes.OleDb;
        //            break;
        //        case "System.Data.SqlClient":
        //        default:
        //            _helper.DatabaseType = Helper.DatabaseTypes.Sql;
        //            break;
        //    }
        //    return _helper;        //}
                private static SqlConnection connection;
        public static SqlConnection Connection
        {
            get
            {
                string connectionString = ConfigurationManager.ConnectionStrings["WEBDB"].ConnectionString;
                if (connection == null)
                {
                    connection = new SqlConnection(connectionString);
                    connection.Open();
                }
                else if (connection.State == System.Data.ConnectionState.Closed)
                {
                    connection.Open();
                }
                else if (connection.State == System.Data.ConnectionState.Broken)
                {
                    connection.Close();
                    connection.Open();
                }
                return connection;
            }
        }

        {

        }        public SqlDataReader GetReader(string safeSql)
        {

            SqlDataReader reader = cmd.ExecuteReader();
            return reader;
        }        public SqlDataReader GetReader(string sql, params SqlParameter[] values)

        }        public DataTable GetDataSet(string safeSql)
        {
            DataSet ds = new DataSet();

}
调用的时候：

        /// New Info

        /// <param name="pm"></param>
        /// <returns></returns>
