namespace ConsoleApp
{
    class Program

        static void Main(string[] args)
        {
            using (SPSite site = new SPSite("https://localhost"))
            {
                SPField fld = site.RootWeb.AvailableFields[SPBuiltInFieldId.Attachments];
                Console.WriteLine("The {0} field is used in:\n", fld.Title);

                ICollection<SPFieldTemplateUsage> collection = fld.ListsFieldUsedIn();
                foreach (SPFieldTemplateUsage usage in collection)
                {
                    SPWeb web = site.AllWebs[usage.WebID];
                    SPList list = web.Lists[usage.ListID];
                    Console.WriteLine("{0} list in {1}", list.Title, web.Title);

                    web.Dispose();
                }
            }
            Console.Write("\nPress ENTER to continue....");
            Console.Read();
        }
    }
}

    Sub Main()
        Using site As New SPSite("https://localhost")

            Console.WriteLine("The {0} field is used in:" & vbLf, fld.Title)

            Dim collection As ICollection(Of SPFieldTemplateUsage) = fld.ListsFieldUsedIn()
            For Each usage As SPFieldTemplateUsage In collection
                Dim web As SPWeb = site.AllWebs(usage.WebID)
                Dim list As SPList = web.Lists(usage.ListID)
