Fetch the list of all the sitecollection and subsites under the webapplication and create a sharepoint menu

public class _starter : MasterPage
    {
        protected Menu CustomMenu;

        protected void Page_Load(object sender, EventArgs e)
        {
            using (SPSite site = new SPSite(SPContext.Current.Site.Url))
            {
                SPWebApplication webapp = site.WebApplication;
                CustomMenu.Items.Clear();
                BeginProcess(webapp);
            }
        }

        public void BeginProcess(SPWebApplication webApp)
        {
            //Execute any logic you need to against the web application
            //Iterate through each site collection
            foreach (SPSite site in webApp.Sites)
            {
                using (SPWeb oSPWeb = site.OpenWeb())
                {
                    MenuItem parentMenuItem = new MenuItem(oSPWeb.Title, oSPWeb.Title, "", oSPWeb.Url);
                    CustomMenu.Items.Add(parentMenuItem);
                    if (oSPWeb.Webs.Count > 0)
                    {
                        RecursiveWebCheck(oSPWeb, parentMenuItem);
                    }
                }
            }
        }

        private void RecursiveWebCheck(SPWeb parentoSPWeb, MenuItem parentMenuItem)
        {
            foreach (SPWeb web in parentoSPWeb.Webs)
            {
                //web.Dispose();
                //if (parentoSPWeb.Webs.Count > 0)
                //{
                MenuItem childMenuItem = new MenuItem(web.Title, web.Title, "", web.Url);
                parentMenuItem.ChildItems.Add(childMenuItem);
                RecursiveWebCheck(web, childMenuItem);

Set Master page when new sub site is created

Step 1:

Step 3:
Choose Web events as Event Receiver type
and select "A Site was provisioned"

Step 4:

    public override void WebProvisioned(SPWebEventProperties properties)

        {

            SPWeb topLevelSite = properties.Web;

            string WebAppRelativePath = topLevelSite.Url;

            if (!WebAppRelativePath.EndsWith("/"))

            {

                WebAppRelativePath += "/";

            }

            topLevelSite.MasterUrl = WebAppRelativePath +

                                          "_catalogs/masterpage/Muthuvel2SpCustomMaster.master";

            topLevelSite.CustomMasterUrl = WebAppRelativePath +

                                   "_catalogs/masterpage/Muthuvel2SpCustomMaster.master";

            topLevelSite.UIVersion = 4;

            topLevelSite.Update();

      }

Step 5:

Deploy the application.

Step 6:

Go the the application and create new site. The master page applied for the newly created site.
