        static void Main(string[] args)
        {
            Application app = new Application();
            DBProviderInfos dbprovInfos = app.DBProviderInfos;

            // Search for the MediaCatalogDB provider in the collection
            if (dbprovInfos.Contains(0))
                Console.WriteLine("The collection contains {0} provider", dbprovInfos[0].Name);
            else
                Console.WriteLine("The collection does not contain {0} provider", dbprovInfos[0].Name);
        }
    }

            Dim dbprovInfos As DBProviderInfos =  app.DBProviderInfos 
 
            ' Search for the MediaCatalogDB provider in the collection
            If dbprovInfos.Contains(0) Then
                Console.WriteLine("The collection contains {0} provider", dbprovInfos(0).Name)
