Send email with dataset as email body

I am trying to send an email with a dataset as the body. When the user clicks a button, my code loops through an asp datagrid on the webpage, and for all the rows that are checked on the datagrid, then an email is sent out with information from a dataset. How do I get the data from the dataset so that I can send the data as the body of my email?

' Variable which will send the mail
    Dim obj As System.Web.Mail.SmtpMail
 
    ''Variable to store the attachments 
    'Dim Attachment As System.Web.Mail.MailAttachment
 
    'Variable to create the message to send
    Dim Mailmsg As New System.Web.Mail.MailMessage()
