How can I get the root site collection from SPContext.Current?

Question

With SPContext.Current I can get the current site or current web. However, I would like to get the root site collection for my current web application. I know that I can get the web application from SPContext.Current.Site.WebApplication but is there a simple way to get the root site collection from that?

Answer 1

// root site – eg. Web App url
string rootSiteCollectionURL = SPContext.Current.Web.Site.WebApplication.Sites[0].Url;

// site collection url
string SiteCollectionURL = SPContext.Current.Web.Site.Url;
