[YouTube-API] Re: Unsubscribe Problem.

Hello Irata,

In order to unsubscribe your request needs to know the unique
subscription id associated with the subscription. Knowing the channel
name isn't enough. (This is documented at the protocol level at
http://code.google.com/apis/youtube/2.0/developers_guide_protocol_subscriptions.html#Deleting_a_subscription)

So you could take that code that retrieves all subscriptions (the
entries will have the proper subscription id pre-populated in that
case) and in the for loop that iterates through the subscriptions, you
could check each one to see if the subscription.UserName property
matches the name of the channel you want to unsubscribe to. If it
does, you could call subscription.SubscriptionEntry.Delete() and break
out of the loop. If it doesn't match, just go on to the next entry in
the loop.

Cheers,
