本文个人在深圳游玩的时候突然想到的...这几周就有想写几篇关于输入数字的笔记，所以回家到之后就奋笔疾书的写出来发布了
------------------------------DAL层：--------------------------
/// <summary>
/// 分页获得数据列表
/// </summary>
public DataTable GetListDataTable(int PageSize, int PageIndex)
{
SqlParameter[] parameters = {
new SqlParameter("@PageSize", SqlDbType.Int),
new SqlParameter("@PageIndex", SqlDbType.Int)
};
parameters[0].Value = PageSize;
parameters[1].Value = PageIndex;
return DbHelperSQL.RunProcedureDataTable("pro_fenye", parameters);
}
--------------------BLL层：--------------------------
public DataTable GetListDataTable(int pagesize, int pageindex)
{
return dal.GetListDataTable(pagesize, pageindex);
}
------------------DbHelperSQL:-----------------------
public static DataTable RunProcedureDataTable(string storedProcName, IDataParameter[] parameters)
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
DataTable dt = new DataTable();
connection.Open();
SqlDataAdapter sqlDA = new SqlDataAdapter();
sqlDA.SelectCommand = BuildQueryCommand(connection, storedProcName, parameters);
sqlDA.Fill(dt);
connection.Close();
return dt;
}
}

文章结束给大家分享下程序员的一些笑话语录：
人脑与电脑的相同点和不同点，人脑会记忆数字，电脑也会记忆数字；人脑会记忆程序，电脑也会记忆程序，但是人脑具有感知能力，这种能力电脑无法模仿，人的记忆会影响到人做任何事情，但是电脑只有程序软件。比尔还表示，人脑与电脑之间最重要的一个差别就是潜意识。对于人脑存储记忆的特别之处，比尔表示，人脑并不大，但是人脑重要的功能是联络，人脑会把同样的记忆存储在不同的地方，因此记忆读取的速度就不相同，而这种速度取决于使用的频率和知识的重要性。人脑的记忆存储能力会随着年龄增长而退化，同时记忆的质量也会随着年龄退化。经典语录网
