select @sec=us.Nm_societ,@vil=vil.Nom_ville,@cntr=cn.typContra,@dat=emp.Dat_creat
from OffrEmplwa emp,typ_Uzrs us,sectr_Activit sec,fonkcion fnk ,Vlle vil,Expriens ex
,TypContra cn,Rolle rl where emp.Id_Uzr=us.Id_user and emp.Id_veil=vil.Id_vll
and emp.Id_Contra=cn.IdContra and us.Id_roole=rl.Id_rol
and us.Id_roole=1 and emp.NmPost like '%@offPst%'
group by emp.Id_OffrEmp,us.Nm_societ,emp.NmPost,vil.Nom_ville

{
DataTable dt = null;
using (SqlConnection cnx = Conection.GetDbConnection())
{
using (SqlCommand cmd = new SqlCommand("LtoffrEmpPst", cnx))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@offPst", SqlDbType.NVarChar,60).Value = dUser.NmPst;
cnx.Open();
cmd.ExecuteNonQuery();
dt = new DataTable();
SqlDataReader dr = cmd.ExecuteReader();
dt.Load(dr);
dr.Close();

Since they are output parameters you need to add them to the cmd.Parameters collection. For example, see here http://stackoverflow.com/questions/12174399/accessing-sql-server-stored-procedure-output-parameter-in-c-sharp[^]

Alternatively, and preferably in my opinion, you don't use output parameters but instead just run a normal Select statement and then you can access the fields that are selected by using dr["fieldName"]

Try following code:

C#

public DataTable offemplistBypst(DTO dUser)
{
DataTable dt = null;
using (SqlConnection cnx = Conection.GetDbConnection())
{
using (SqlCommand cmd = new SqlCommand("LtoffrEmpPst", cnx))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@offPst", SqlDbType.NVarChar,60).Value = dUser.NmPst;
SqlParameter parm2 = new SqlParameter("@sec", SqlDbType.VarChar);
    parm2.Size = 60;
    parm2.Direction = ParameterDirection.Output; 
    cmd.Parameters.Add(parm2);
SqlParameter parm3 = new SqlParameter("@vil", SqlDbType.VarChar);
    parm2.Size = 60;
    parm2.Direction = ParameterDirection.Output; 
    cmd.Parameters.Add(parm3);
SqlParameter parm4 = new SqlParameter("@cntr", SqlDbType.VarChar);
    parm2.Size = 60;
    parm2.Direction = ParameterDirection.Output; 
    cmd.Parameters.Add(parm4);
SqlParameter parm5 = new SqlParameter("@dat", SqlDbType.DateTime);
    parm2.Size = 60;
    parm2.Direction = ParameterDirection.Output; 
    cmd.Parameters.Add(parm5);

cnx.Open();
cmd.ExecuteNonQuery();
dt = new DataTable();
SqlDataReader dr = cmd.ExecuteReader();
dt.Load(dr);
dr.Close();
dr.Dispose();
return dt;
}
}
}

Solution 3

You can use cmd.Parameter.AddWithValue("@your_param",value) method instead.
