Good Day Experts and Happy New Year!

I have a new request for one of my projects today.  

While iterating through my DataReader I am inserting records into a SQL table.  Then at the end of the function I am sending and email out to Users before displaying a complete messageBox.  I need to be able to save each key value of the inserted records so I can send them in the body of the email.  The number of records will not be known.  The DataReader could have 5 or 50 or 100 or more to insert.  

So how can I save the primary key values of each record inserted so I can send later in the email?

Thanks for the insight,

Are you generating your primary key on the client side, or is your database using an identity field? Are you inserting the records using a stored procedure, or are you building your SQL and then executing it for each row?

Because you can read datareader only once, you can first store it in a variable (maybe array). Then use this variable value in your code to perform during the operation and when you need it for emailing.

It's going to depend upon how you do your insert.  If, when you insert the record, the row or field that contains the primary key is being returned (for example, using ExecuteScalar) you could insert this returned value into a collection; i.e. - a list or array.  You could then send out an email with the contents of this collection.
