The URI of the CookieCollection to be added to the CookieContainer.


The CookieCollection to be added to the CookieContainer.

Exception typeCondition


cookies is a null reference (Nothing in Visual Basic).


The domain for one of the cookies in cookies is a null reference (Nothing in Visual Basic).


One of the cookies in cookies contains an invalid domain.

If you add a Cookie instance for just one specific host, do not set the Domain property of the Cookie instance. This is set automatically, based on the URI.

If your URI corresponds to your local domain and sends to all the hosts on the local domain, set the CookieDomain property equal to ".local". Otherwise, make sure it matches the host name used in the URI.

If Count equals Capacity, one or more Cookie instances is removed from the container before adding the cookie parameter. Enough Cookie instances are removed to bring Count below Capacity as follows: if there are expired instances in scope they are cleaned up. If not, then the least recently used CookieCollection is found and removed from the container.
