 SPSiteAdministration oSPSiteAdministration = new SPSiteAdministration(siteCollectionURL);
 float scDiskUsage = oSPSiteAdministration.DiskUsed;
 float sizeOfSiteCollection = (scDiskUsage / (1024 * 1024));  // In MB

 string siteCollectionURL = “https://localhost:80/sites/TestSite”;
 SPSite oSPSite = new SPSite(siteCollectionURL);
 SPWeb oSPWeb = oSPSite.RootWeb;
 float totalSubSitesUsage = GetWebSize(oSPWeb);

 {
   float total = 0;
   foreach (SPFolder folder in web.Folders)
   {
     total += GetFolderSize(folder);
   }
   foreach (SPWeb subweb in web.Webs)
