I will try to be as concise as I can:The goal: trying to universalize a specific section of a project, that is dealing with the SQL database transactions.To assist you with your answer, I've pasted the following (just for reference):a usage code: GetTestOfTablTime() returns a DataTable class: SQLDBInteraction is another class - responsible for the final(SQL transaction) stage In this code below, I am constructing what I call: Stored Procedure's Meta Data.  That class is the one that holds all of the SQL Db SPs.HTSPs (HT is the  company's aliases) is holding each SP required) parameters.  HTSPs class contains another sub Class.  For all SPs Names, it only has const strings for each SP name.public sealed class HTSPs{//so for example this is one of the members of this class - a stored procedure//its mission: get evnents with specified id OF specified userId in spec' month, year..    public sealed class GetTimesWithCustomerNames    {        //if I DO need Constructor for its parameters how do I properly format the constructor?        public GetTimesWithCustomerNames()        {            Userid.ParameterName = ParNameUserid;            Month.ParameterName = ParNameMonth;            Year.ParameterName = ParNameYear;            EventId.ParameterName = ParNameReasonid;        }        const string ParNameUserId = @userId,                     ParNameMonth = @month,                     ParNameYear = @year,                     ParNameEventId = @eventId;        public static SqlParameter Userid = new SqlParameter();        public static SqlParameter Month = new SqlParameter();        public static SqlParameter Year = new SqlParameter();        public static SqlParameter EventId = new SqlParameter();                }}The issue is:  how do I initialize the contractor?  What is the proper way to have your simple customized StoredProcedure MetaData?  I've currently completed the implementation of the method below (apart from that issue).USAGE This is a method that returns DataTable while using the HTSPs class / constructor.using SPTime = HT_DBSchema.HTSPs.GetTimesWithCustomerNames;private DataTable GetTestOfTablTime(){    SQLDBInteraction.DataContainer DC_Time = new SQLDBInteraction.DataContainer();    SQLDBInteraction.SqlParamList parmsTime = new SQLDBInteraction.SqlParamList();    Dictionary<SqlParameter, int> SqlCmdParDict = new Dictionary<SqlParameter, int>();    parmsTime.SqlCmd.CommandType = CommandType.StoredProcedure;    parmsTime.SqlCmd.CommandText = AppDb.MetaSqlSProc.Time.Name;    parmsTime.SP_Name = AppDb.MetaSqlSProc.Time.Name;    parmsTime.TableName = AppDb.MetaSqlTable.Time.Name;    //While folowing implementation Does Work I comented it out to try using the SP Struct    //ParmsTTime.SP_Params.Add(new SqlParameter(SPTime.ParNameMonth, 9));    //ParmsTTime.SP_Params.Add(new SqlParameter(SPTime.ParNameReasonid, 1));    //ParmsTTime.SP_Params.Add(new SqlParameter(SPTime.ParNameYear, 2012));    //ParmsTTime.SP_Params.Add(new SqlParameter(SPTime.ParNameUserid, 3571));    //here's where I'm currently stuck, in section below. trying to assign values for the SqlCommand    parmsTime.SqlCmd.Parameters.AddWithValue(SPTime.ParNameMonth, 9);    parmsTime.SqlCmd.Parameters.AddWithValue(SPTime.ParNameYear, 2012);    parmsTime.SqlCmd.Parameters.AddWithValue(SPTime.ParNameReasonid, 1);    SPTime.Userid.Direction = ParameterDirection.Input;    SPTime.Userid.SqlValue = 3571;    return DC_Time.LocalTbl_V3(ParmsTime); }UPDATEThe last lines of the code above is trying to implement the parameters assignment, thus it will no longer be required to use:SQLDBInteraction.SqlParamList.SP_Params (which is List<SqlParameter>).And instead, I would really like to be able to use SQLDBInteraction.SqlParamList.SqlCmd.Parameters as it is already used for most of the required steps to interact with the database.This is how I will drop some unnecessary usage of extra variables while at the same time I wanted to assign SqlCmd (parmsTime.SqlCmd.Parameters.Add(......)) with the struct - SPTime Real SqlParameters instead of using the strings that represents their name (e.g.  parameter.name - (SPTime.ParNameMonth, someValue)).Final stage- SQL transactionThe SQLDBInteraction class that does the transaction:public class SQLDBInteraction{    public class SqlParamList    {        public SqlCommand SqlCmd = new SqlCommand();        public List<SqlParameter> SP_Params = new List<SqlParameter>();        public String SP_Name;        public string TableName;        public string SelectCommand;        ///public SqlCommandType SelectedCmdType;    }    public class DataContainer    {        public DataTable LocalTbl_V3(SqlParamList Params)        {            SqlConnection sqlConnection;            DataTable Usrs = new DataTable(Params.TableName);            SqlDataAdapter sqlDataAdapter;            using (sqlConnection = new SqlConnection(WebConfigurationManager.ConnectionStrings[HTConn].ConnectionString))            {                sqlConnection.Open();                using (Params.SqlCmd.Connection = sqlConnection)                {                    using (sqlDataAdapter = new SqlDataAdapter(Params.SqlCmd.CommandText, sqlConnection))                    {                        if (sqlDataAdapter.SelectCommand.Parameters.Count > 0 == false)                        {                            sqlDataAdapter.SelectCommand = Params.SqlCmd;                            sqlDataAdapter.Fill(Usrs);                        }                    }                }            }            return Usrs;        }I will really appreciate it if someone will find what am I doing wrong with the part of the stored procedure's parameters assigned to the SQL command.
