Error: Index was outside the bounds of the array

Hi,

I'm getting the following error when I try to populate a label control in vb.net.  Here is the error:


Server Error in '/Prototype_I' Application.

Index was outside the bounds of the array.

Here is my vb code:

Dim dbreader As SqlDataReader = dbcmd.ExecuteReader
If dbreader.HasRows Then

dbreader.Read()
lblUnit.Text = dbreader.Item(0)
lbl_BusinessName.Text = dbreader.Item(1)
lbl_MailCode.Text = dbreader.Item(2)

......

lbl_ManagerName.Text = dbreader.Item(15 + 17)
lbl_LevelAuth.Text = dbreader.Item(18)


What I am trying to do is input the first and last name of the Manager into one label "ManagerName".  Is there a way to concatenate the two columns to be displayed in one label using the datareader?

I have listed the datareader to populate the fields in an array based on the number of columns in the database table.  For instance, "Business Unit" is the first column in the database table, therefore, I am asking for the first value in the table to display in the first label (0) "Business Unit" and so on, until I get to column 15 and 17, which contain the First and Last name (respectively) of the manager.  I know I could use two labels and/or two <td>tags, but I've already coded the table in HTML and I would like to avoid having to add more cells to the table (each label is in one <td>).

 Thanks!
