What is the difference between below way of getting the reference of SPSite object in FeatureActivated() of sharepoint?

1.

    properties)
        {
           SPSite site = properties.Feature.Parent as SPSite;
        //some code
        }

                 **VS**

2.

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
   SPSite site = SPContext.Current.Site;
//some code
}

Answer 1

You can't get SPContext inside handlers - this is by design. You should use event properties passed as argument to the handler to get reference to current web, list item etc.

Timer Jobs, Feature Receivers, Service Application Solutions are not invoked synchronously by user action, so they are not associated with HTTPRequest and thus they do not have access to SPContext.

You have to get it :

SPSite site = properties.Feature.Parent as SPSite;
