Programatically creating site collections

Scenario:
You want to programtically create many site collections.

Solution:
In-spite of going through UI to create all the site, a small utility can help.

Code:

// for the top-level site
string url = "/";

// this is the MS language Locale ID. 
uint LCID = 1033;

// this is the site template for the 
// Publishing Site - Collaboration Portal merged site definition
string template = "SPSPORTAL";

// create a site collection with an out of the box site definition
SPSite TopSiteCollection = webApp.Sites.Add(url, 
  "Top Site collection", "Description of this site", 
  LCID, template, "domain\\administrator", 
  "owner name", "email address");

// close the site collection
TopSiteCollection.Close();
