Hey Arun,
I have done the same job. Hope this code will help you.
using (SPSite siteCollectionOuter = new SPSite("Any SC url in which u want to create site."))
SPWebApplication webApp = siteCollectionOuter.WebApplication;
SPSiteCollection siteCollection = webApp.Sites;
SPContentDatabase contentDatabase =
siteCollection.WebApplication.ContentDatabases.Add(ServerName, New Database Name, Admin Name,
"Admin Password",25,50, 0);
//Above line will create new content DB
contentDatabase.Update();
siteCollection.WebApplication.Update();
SPSite newSite = contentDatabase.Sites.Add("New SC Url", "SC Title", SC Desctipyion, 1033,
15, "STS#0", "SC Admin", "Admin", "admin password",
"User 2", "User NAme", "Password");
//Ablove line will create new SC in to the Content DB
//add the upper limit for the site collection
SPQuota quota;
quota = new SPQuota {StorageMaximumLevel = 2510220};
newSite.Quota = quota;
// And update the site collection and the content database
newSite.RootWeb.Update();
contentDatabase.Update();
