How to Pass a List from c# to an oracle procedure

I have a code that sends data as a string list from the textbox to oracle procedure.
I get the values in the textbox below.
public List<string> TxtPieceList()
{
List<string> pieces = new List<string>();
for (int i = 0; i < txtListe.Lines.Count(); i++)
{
pieces.Add(txtListe.Lines[i]);
}
return pieces;
}
There are two variables I sent.
p_piece_id is assigned value from textbox.
p_mother_check is assigned value from checkbox.
Then I pass this data into the procedure :
public void gridDoldur()
{
var annesecilimi = cbMother.Checked;
List<string> gridList = TxtPieceList();
using (OracleConnection con = new OracleConnection(connectionString))
{
OracleCommand cmd = new OracleCommand("Z_LABEL_PRINTER_GR.LabelPieceList", con);
con.Open();
cmd.CommandType = CommandType.StoredProcedure;
try
{
OracleParameter p_piece_id = new OracleParameter();
OracleParameter p_mother_check = new OracleParameter();
p_piece_id.OracleDbType = OracleDbType.Varchar2;
p_mother_check.OracleDbType = OracleDbType.Varchar2;
p_piece_id.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
p_mother_check.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
p_piece_id.Value = from emp in gridList select emp;
p_mother_check.Value = annesecilimi;
cmd.Parameters.Add(p_piece_id);
cmd.Parameters.Add(p_mother_check);
cmd.Parameters.Add("p_rc", OracleDbType.RefCursor).Direction = ParameterDirection.Output;
OracleDataAdapter da = new OracleDataAdapter(cmd);
OracleCommandBuilder commandBuilder = new OracleCommandBuilder(da);
DataTable dt = new DataTable();
da.Fill(dt);
this.gridPieceList.Visible = true;
gridPieceList.DataSource = dt;
}
But I get an error in the procedure that returns value by oracle.
OracleParameter value is invalid.
CREATE OR REPLACE PACKAGE BODY Z_LABEL_PRINTER_GR
AS
T_STRING_LIST DEFINAION : TYPE "T_STRING_LIST" AS TABLE OF VARCHAR2(2000)
PROCEDURE LabelPieceList(p_piece_id IN T_STRING_LIST,
p_mother_check IN varchar2,
p_rc OUT sys_refcursor)
IS
BEGIN
IF p_mother_check='False' THEN
OPEN p_rc FOR
SELECT PIECE_NUM_ID,PIECE_ID,ACTUAL_WEIGHT,ACTUAL_THICK,ACTUAL_WIDTH
FROM piece WHERE PIECE_ID IN (SELECT COLUMN_VALUE FROM TABLE(p_piece_id))
ELSE
OPEN p_rc FOR
SELECT PIECE_NUM_ID,PIECE_ID,ACTUAL_WEIGHT,ACTUAL_THICK,ACTUAL_WIDTH FROM piece WHERE PIECE_ID IN(
(SELECT COLUMN_VALUE FROM TABLE(p_piece_id)) AND PH.STATUS=2);
END IF ;
END LabelPieceList;
-- Package body
END Z_LABEL_PRINTER_GR;

Web API to call a stored procedure to insert/update DB

I have been working on creating the Web API that accepts the input parameter and calls a Stored Procedure passing the input parameter we received that insert/updates the Account Table in the Database. Now that is perfectly , but my API also need to select the record which was updated/inserted and return them as response
public class ProjectNameCreationController : ApiController
{
[HttpGet]
public HttpResponseMessage Get(string Account)
{
if (string.IsNullOrEmpty(Account))
{
return Request.CreateResponse(new { error = "Input parameters cannot be Empty or NULL" });
}
string strcon = ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString;
SqlConnection DbConnection = new SqlConnection(strcon);
DbConnection.Open();
SqlCommand command = new SqlCommand("[dbo].[usp_InserUpadte]", DbConnection);
command.CommandType = CommandType.StoredProcedure;
//create type table
DataTable table = new DataTable();
table.Columns.Add("AccountID", typeof(string));
table.Rows.Add(Account);
SqlParameter parameter = command.Parameters.AddWithValue("#account_TT", table);
parameter.SqlDbType = SqlDbType.Structured;
parameter.TypeName = "account_TT";
command.ExecuteNonQuery();
Now I am not sure if we will able to select the record that was now insert/updated as part of the Stored Procedure or will I have to create a Query seperately like below
string strQuery = "select AccountID,CounterSeq from Account where AccountID = #accountID ";
var cmd = new SqlCommand(strQuery);
cmd.Parameters.AddWithValue("#accountID",Account);
Because I will have to Return the response as AccountID-CounterSeq (Eg: IT-1) when the API is called like http://localhost/api/ProjectNameCreation?Account=IT. How can I deal with this. Any help is greatly appreciated

You have to change your procedure as below it will return a record of last inserted or updated.
**--for insert**
IF #StatementType = 'Insert'
BEGIN
insert into Account (first_name,last_name,salary,city) values( #first_name, #last_name, #salary, #city)
--below line to return last inserted record
select * from Account where accountid= SCOPE_IDENTITY()
END
**--for Update**
IF #StatementType = 'Update'
BEGIN
UPDATE Account SET
First_name = #first_name, last_name = #last_name, salary = #salary,
city = #city
WHERE accountid= #accountid
--below line to return last Updated record
select * from account where accountid = #accountid

C# SQL command line monodevelop

I am running monodevelop on arch linux and I tried to insert some values into a local database , but when I run it from a button the application closes.The file is created and it have all fields.
Here is my code:
SqliteConnection m_dbConnection = new SqliteConnection ("Data Source=GOOD_FOOD.sqlite;Version=3;");
m_dbConnection.Open ();
int id;
string get = "SELECT LAST(id_client) FROM Clienti";
SqliteCommand comSelect = new SqliteCommand (get, m_dbConnection);
int? getid = (int?)comSelect.ExecuteScalar();
if (getid.HasValue) {
id = Convert.ToInt32(getid) + 1;
} else
{
id = 1;
}
// create account
string create = "INSERT INTO Clienti (id_client, parola, nume, prenume, adresa, email) VALUES (#id, #parola, #nume, #prenume, #adresa, #email)";
SqliteCommand createcmd = new SqliteCommand (create, m_dbConnection);
createcmd.Parameters.AddWithValue("#id", id);
createcmd.Parameters.AddWithValue ("#parola", password.Text);
createcmd.Parameters.AddWithValue("#nume", name.Text);
createcmd.Parameters.AddWithValue ("#prenume", secondname.Text);
createcmd.Parameters.AddWithValue("#adresa", address.Text);
createcmd.Parameters.AddWithValue ("#email", email.Text);
createcmd.ExecuteNonQuery ();
m_dbConnection.Close ();

The soulution :
Use try{} catch{} and change id = Convert.ToInt32(getid) + 1; to id = getid.Value +1;
Change "SELECT LAST(id_client) FROM Clienti"; to "SELECT id_client FROM Clienti ORDER BY id_client DESC;";

SQL STORED PROCEDURE
alter procedure SPselbdralt

as
begin
select brandname from rpmallot where comname=(select id from companydetails where comname=#comname)
end
please solve my problem as soon as possible I am working on a live project

Please make sure, You are using the correct sp
I want to show the stored procedure but i am getting the error of
Procedure SPselcocpd has no parameters and arguments were
supplied.
In code you are calling different SP SPselcocpd
SqlCommand cmd = new SqlCommand("SPselcocpd"); // Here it is SPselcocpd
And SQL SP is
alter procedure SPselbdralt
Confirm that you are calling the correct SP

You are calling wrong stored procedure.
Change
SqlCommand cmd = new SqlCommand("SPselcocpd");
To
SqlCommand cmd = new SqlCommand("SPselbdralt");

Fail to fill datatable using data adapter

i'm try to match the data with the database and using dataadapter to fill my datatable. if matched, fill the datatable with dataadapter. if not match, show msg. but my username and password is matched with database, it still show msg. under debug mode, username and password is all pass through but not fill in the datatable.
using (OracleConnection conn = new OracleConnection())
{
conn.ConnectionString = connStr;
conn.Open();
string sql = #"select user_id, password, status, role_id, email, contact_no,
last_login_date, created_by, last_update_date, last_update_by
from users where user_id = :userID and password = :pwd";
using (OracleCommand cmd = new OracleCommand())
{
cmd.Connection = conn;
cmd.CommandText = sql;
cmd.Parameters.Add("userID", OracleType.VarChar).Value = userID;
cmd.Parameters.Add("pwd", OracleType.VarChar).Value = pwd;
DataTable dt = new DataTable();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
adapter.Fill(dt);
if (dt.Rows.Count <= 0)
{
msg = "Invalid Login ID or Password";
}
return dt;
}
}
the dt.Rows.Count is 0. but I checked username and password is exactly same with the database.

SQL:
create procedure sp_authenticate
(
#userId varchar(50),
#pass varchar(50)
)
as
begin
select user_id, password, status, role_id, email, contact_no,
last_login_date, created_by, last_update_date, last_update_by
from users where user_id = #userid and password = #pass
end
C# code:

cmd.CommandText = "sp_authenticate"; //name of your procedure
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#userid", OracleType.VarChar,50).value=userID;
cmd.Parameters.Add("#password", OracleType.VarChar,50).value=pwd;
DataTable dt = new DataTable();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
adapter.Fill(dt);
