Örnek XML belgeleri açıklamaları

Bu makale, C# dil öğelerinin çoğuna XML belge açıklamaları eklemeye yönelik üç örnek içerir. İlk örnekte, bir sınıfı farklı üyelerle nasıl belgelediğiniz gösterilmektedir. İkinci örnekte sınıfların veya arabirimlerin hiyerarşisi için açıklamaları nasıl yeniden kullanabileceğiniz gösterilmektedir. Üçüncü örnek, genel sınıflar ve üyeler için kullanılacak etiketleri gösterir. İkinci ve üçüncü örneklerde, ilk örneğin kapsadığı kavramlar kullanılır.

C# dili başvuru belgesi, C# dilinin en son yayımlanan sürümünü gösterir. Ayrıca, yaklaşan dil sürümü için genel önizlemelerdeki özelliklere yönelik ilk belgeleri içerir.

Belgelerde ilk olarak dilin son üç sürümünde veya geçerli genel önizlemelerde sunulan tüm özellikler tanımlanır.

Tavsiye

Bir özelliğin C# dilinde ilk tanıtıldığı zamanları bulmak için C# dil sürümü geçmişi makalesine bakın.

Bir sınıfı, yapıyı veya arabirimi belgele

Aşağıdaki örnekte ortak dil öğeleri ve bu öğeleri açıklamak için büyük olasılıkla kullanacağınız etiketler gösterilmektedir. Belge açıklamaları, sınıfın kendisi yerine etiketlerin kullanımını açıklar.

Belge eklemek, kaynak kodunuzu kitaplığınızın kullanıcılarına yönelik büyük açıklama kümeleriyle karmaşık hale gelebilir. <Include> XML açıklamalarınızı kaynağınızdan ayırmak için etiketini kullanın. Kaynak kodunuz şu etiketi kullanarak bir XML dosyasına başvurur <Include> :

/// <include file='xml_include_tag.xml' path='MyDocs/MyMembers[@name="test"]/*' />
class Test
{
    static void Main()
    {
    }
}

/// <include file='xml_include_tag.xml' path='MyDocs/MyMembers[@name="test2"]/*' />
class Test2
{
    public void Test()
    {
    }
}

İkinci dosya, xml_include_tag.xml, dökümantasyon açıklayıcı yorumları içerir.

<MyDocs>
    <MyMembers name="test">
        <summary>
        The summary for this type.

Sınıfların ve arabirimlerin hiyerarşisini belgele

<inheritdoc> öğesi, bir tür veya üyenin belge açıklamalarını bir temel sınıftan veya arabirimden devraldığı anlamına gelir. Aynı türdeki bir üyeden açıklamaları devralmak için <inheritdoc> özniteliğiyle cref öğesini de kullanabilirsiniz. Aşağıdaki örnekte bu etiketi kullanmanın yolları gösterilmektedir. inheritdoc özniteliğini bir türe eklediğinizde, üye açıklamaları da devralınır. Türetilmiş türdeki üyelere açıklamalar yazarak devralınan açıklamaların kullanılmasını engelleyebilirsiniz. Derleyici, devralınan açıklamalar yerine bu açıklamaları seçer.
