I have a web page that does a bulk insert of a csv file to a database but I want to be able to look at the file before it's uploaded to make sure its in the proper format. A few of the things that I'm looking for are
Correct phone number format (if it doesnt have an area code, one needs to be given to it ... this will all be done with a 512 area code)
Correct number of fields for the database. Right now there are only
ID
Patient Name
Doctors Name
Appointment Time
Appointment Date
Current Time
Result
ID, Current Time and Result are all supplied either by the database or the program I'm running in the background so they don't have to be manipulated in any way.
And finally the datetime is formatted as yyyymmdd:hhmm
and I will need all incoming data to comply with that.
I know that data can be read with ado.net but this is new to me. Does any one have any kind of idea as to what would be the best way to go about this?
Thank you
Doug
