Answer 1

I'm not going to give you the code simply because you should attempt to solve it yourself first or at least explain that you have some knowledge of how you would go about it however i will help in give you a little insight.

You can do this a couple of ways

1 Get the SPWeb object where the item is supposed to be. Normally context of the site.

Get the list where the item is supposed to live SPWeb object.lists[listname or guidhere]

Loop through the list checking if anything matches in each item or even checking if the object matches the object

The other way is to use an SPQuery object

set the SPquery.query = "YOUR CAML STATEMENT HERE"

SPList<yourlist>.GetItems(SPQuery object)

if the above returns >0 items you have a match

Increment by one

This should give you a good starting block
