I have a problem with this code, because it gives me following error message 
Object reference not set to an instance of an object when I use the line
values[countValues] = reader2.GetString("textinfo"); in the code below

Can someone help me?


      <pre lang="C#">
public static string[] values;
int countValues = 0;


 using (var connection = new MySqlConnection(connString))
                {
                    connection.Open();
                    string query = "select * from showvalues where idvalue = '" + idStatus + "'";
                    using (var command2 = new MySqlCommand(query, connection))
                    {
                        using (var reader2 = command2.ExecuteReader())
                        {
