Activate features through code

For a recent project I did, I had to activate a feature programatically.

I needed some research to achieve this, so I thought I'd just put it in a post. It's only a few lines of code, so nothing hard to do here ...

Basically, what it does is update the FeatureCollection object of a given Site or Site Collection. Adding a feature to this collection automatically activates it.

! Do make sure the feature is already installed in the farm/site/web/... when trying to activate it.

SPWeb web = new SPSite("http://yourserver.com").OpenWeb();

SPFeatureCollection featureCollect = web.Features;

featureCollect.Add(new Guid("xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"), true); //True to force activation

That's all it takes :) 
Hope it helps someone ...

you can also use web.features.add(guid) is a bit less code

It think that's quite obvious, as we just use the SPFeatureCollection assigned to web.Features :|

It's just to make it a little more clear what object it used ...

Please explain how do you get this class to run from feature.xml?

Michael,

I don't think it's adviced to try to run this class from the feature file itself, since the code would only be run at the moment you actually activate the feature ...

Hi

Do you know how to activate farm features through code?

Probably something like SPFarm.Local.FeatureDefinitions.Add(.....)

How do I check if the feature id already activated or not?
