How to insert CookieCollection to CookieContainer?

After I get response from httpwebrequest, I'd like the cookies obtained to save for the purpose of using them in another httbwebrequest. However, I'd need to insert CookieCollection to CookieContainer. How do I do that? Tried to do:

request.Cookiecontainer.add(response.Cookies);

but this keeps getting out of error: Object reference not set to an instance of an object.

request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(response.Cookies);

According to Microsoft:

CookieContainer is a null reference (Nothing in Visual Basic) by default. You must assign a CookieContainer object to the property to have cookies returned in the Cookies property of the HttpWebResponse returned by the GetResponse method.
