Not

Aşağıdaki kod örneği tek dosyalı kod modelini kullanır ve doğrudan arka planda kod dosyasına kopyalandığında düzgün çalışmayabilir. Bu kod örneği, .aspx uzantısına sahip boş bir metin dosyasına kopyalanmalıdır. Web Forms kod modeli hakkında daha fazla bilgi için bkz. ASP.NET Web Forms Sayfa Kodu Modeli.
