Question

I wrote a program in C# where I wanted to get a value from a MySQL Database.

My code is:

MySqlCommand queryReqYear =
      new MySqlCommand(@"SELECT req_year FROM subjects_offered
                         WHERE subj_code= @subj", connectToDB.connection);


queryReqYear.Parameters.AddWithValue("@subj", viewStudents_subj.SelectedValue);

Then I use DataReader

MySqlDataReader reader;
reader = queryReqYear.ExecuteReader();

And then I try to get the value:

while (reader.Read())
    { MessageBox.Show(reader.GetString(0)); }

The field I’m trying to get has a value of 3. I’m trying to display that value but when I execute the event, nothing happens.

EDIT

Okay, I solved the problem by changing SelectedValue to SelectedItem
