取得包含這個節點屬性 (Attribute) 的 XmlAttributeCollection。

public:
 virtual property System::Xml::XmlAttributeCollection ^ Attributes { System::Xml::XmlAttributeCollection ^ get(); };

public virtual System.Xml.XmlAttributeCollection Attributes { get; }

public virtual System.Xml.XmlAttributeCollection? Attributes { get; }

member this.Attributes : System.Xml.XmlAttributeCollection

Public Overridable ReadOnly Property Attributes As XmlAttributeCollection

屬性值

XmlAttributeCollection，包含這個節點的屬性。

如果這個節點的類型為 XmlNodeType.Element，則傳回這個節點的屬性。 否則，這個函式會傳回 null。

範例

下列範例會將新的屬性新增至 XML 檔。

   XmlNode^ root = doc->FirstChild;
   
   //Create a new attribute.
   String^ ns = root->GetNamespaceOfPrefix( "bk" );
   XmlNode^ attr = doc->CreateNode( XmlNodeType::Attribute, "genre", ns );
   attr->Value = "novel";
   
   //Add the attribute to the document.
   root->Attributes->SetNamedItem( attr );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );
}
