I do not clearly understand how to format the SqlDataAdapter for output variables when working with C#
Error Message:
Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
Code Example (Stored Procedure works fine)
private DataTable updateOrdEodHold(DataTable tb, out string mnpft, out string authld, out string trd, out string hld, out string extnow)
{
// start the connection string
string connstr = ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString;
SqlConnection myConn = new SqlConnection(connstr);
// declare Symbol and assign for Errors Catch Exception
string Symbol = "";
string sqlComm = "dbo.UpdateOrdEodHold";
DataTable HoldVals = new DataTable();
SqlDataAdapter dataAdp = new SqlDataAdapter(sqlComm, myConn);
dataAdp.SelectCommand.CommandType = CommandType.StoredProcedure;
string ticker = (string)Convert.ToString(tb.Rows[0]["Ticker"]);
// update Symbol for Catch ex
Symbol = ticker.ToString();
String company = (string)Convert.ToString(tb.Rows[0]["Company"]);
String avgprofit = (string)Convert.ToString(tb.Rows[0]["AvgProfit"]);
String extdte = (string)Convert.ToString(tb.Rows[0]["ExitDate"]);
dataAdp.SelectCommand.Parameters.Clear();
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@ticker", SqlDbType.VarChar, 10));
dataAdp.SelectCommand.Parameters["@ticker"].Value = (string)ticker.ToString();
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@company", SqlDbType.VarChar, 25));
dataAdp.SelectCommand.Parameters["@company"].Value = (string)company.ToString();
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@avgpft", SqlDbType.VarChar, 10));
dataAdp.SelectCommand.Parameters["@avgpft"].Value = (string)avgprofit.ToString();
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@mnpft", SqlDbType.VarChar, 10));
dataAdp.SelectCommand.Parameters["@mnpft"].Direction = ParameterDirection.Output;
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@authld", SqlDbType.VarChar, 6));
dataAdp.SelectCommand.Parameters["@authld"].Direction = ParameterDirection.Output;
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@hld", SqlDbType.VarChar, 6));
dataAdp.SelectCommand.Parameters["@hld"].Direction = ParameterDirection.Output;
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@trd", SqlDbType.VarChar, 6));
dataAdp.SelectCommand.Parameters["@trd"].Direction = ParameterDirection.Output;
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@extnow", SqlDbType.VarChar, 6));
dataAdp.SelectCommand.Parameters["@extnow"].Direction = ParameterDirection.Output;
dataAdp.SelectCommand.Parameters.Add(new SqlParameter("@extdte", SqlDbType.VarChar, 15));
dataAdp.SelectCommand.Parameters["@extdte"].Value = (string)extdte.ToString();
dataAdp.Fill(HoldVals);
mnpft = HoldVals.Rows[0]["MinProfit"].ToString();
authld = HoldVals.Rows[0]["AutoHold"].ToString();
trd = HoldVals.Rows[0]["Trade"].ToString();
hld = HoldVals.Rows[0]["Hold"].ToString();
extnow = HoldVals.Rows[0]["ExitNow"].ToString();
return HoldVals;
