Answer 1

you can use standart ways that you use before in normal queries but in Sql command you must write EXEC before your store procedure name and dont use commandtype like this :

 SqlConnection con = new SqlConnection(["ConnectionString"])
    SqlCommand com = new SqlCommand("EXEC _Proc @id",con);
    com.Parameters.AddWithValue("@id",["IDVALUE"]);
    con.Open();
    SqlDataReader rdr = com.ExecuteReader();
    ArrayList liste = new ArrayList();
    While(rdr.Read())
    {
    liste.Add(rdr[0]); //if it returns multiple you can add them another arrays=> liste1.Add(rdr[1]) ..
    }
    con.Close();
