Örnekler

Aşağıdaki kod örneği, sınıfının özelliğini ve GetKey ve CopyTo yöntemlerini HttpModuleCollection gösterirAllKeys. Örnek, geçerli istek için uygulama nesnesini geçerli HttpContext nesneden alır. Ardından, uygulama örneğinden nesnesini ayıklar HttpModuleCollection ve nesnelerin adlarını IHttpModule görüntüler.
