Solution 2

Something like this (notice I didn't include try/catch/finally block):

C#

SqlConnection conn   = new SqlConnection(connectionstring);
SqlCommand    cmd    = new SqlCommand("proc_udatabase", conn);
SqlDataReader reader = null;
Datatable     data   = new  DataTable();

conn.Open();
cmd.Parameters.Add(new SqlParameter("@string1", "name");
cmd.Parameters.Add(new SqlParameter("@string2", "24");
reader = cmd.ExecuteReader();
if (reader != null)
{
    data.Load(reader);
}
conn.Close();

sql_string = ("Data Source=000.000.000.000;Initial Catalog=GCERP_SEC;User Id=sa;Password=kamikami;");
SqlConnection conn = new SqlConnection(sql_string);
SqlCommand command = new SqlCommand(str_querry, conn);

conn.Open();

command.CommandType = CommandType.StoredProcedure;
command.Parameters.AddWithValue("@string1" ,SecurityModule.userName_AD);
command.Parameters.AddWithValue("@string2", SecurityModule.moduleid);
// SqlDataReader rdr =StoredProcedureCommand.ExecuteReader();

SqlDataReader rdr = command.ExecuteReader();

if (rdr.HasRows)
{
StringBuilder sb = new StringBuilder();
string a;
while (rdr.Read())
{
sb.Append(((int)rdr["fnid_int"]).ToString());
sb.Append("\n");
a = sb.ToString();
function_name(a);
sb.Length = 0;
}

}
else
{
MessageBox.Show("not found");

conn.Dispose();

}
