//自己寫的方法，分頁獲取數(shù)據(jù)列表
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("usp_role_GetDateByPageIndex", parameters);
}
在BLL中調(diào)用GetListDataTable：
public DataTable GetListDataTable(int pagesize, int pageindex)
{
return dal.GetListDataTable(pagesize, pageindex);
}
在DbHelper中添加RunProcedureDataTable方法：
public static DataTable RunProcedureDataTable(string stroreProcName, IDataParameter[] parameters)
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
DataTable dt = new DataTable();
connection.Open();
SqlDataAdapter sqlDA = new SqlDataAdapter();
sqlDA.SelectCommand = BuildQueryCommand(connection, stroreProcName, parameters);
sqlDA.Fill(dt);
connection.Close();
return dt;
}
}
