public string MasterUrl { get; set; }
Property Value
A string that contains the URL of the master page.
The MasterUrl and CustomMasterUrl properties are both set to "/_catalogs/masterpage/default.master" by default. If you subsequently need to delete the default.master file, you must set both of those properties to a different value. If you set just one of them to a different value, an error is raised that suggests that the default.master file is still being used as the master page for the site.
