Definice

Obor názvů:

System.Xml.Serialization

Sestavení:

System.Xml.XmlSerializer.dll

Zdroj:

XmlIncludeAttribute.cs

Získá nebo nastaví typ objektu zahrnout.

public:
 property Type ^ Type { Type ^ get(); void set(Type ^ value); };

public Type? Type { get; set; }

member this.Type : Type with get, set

Public Property Type As Type

Objekt Type , který se má zahrnout.

Příklady

Následující příklad definuje třídu s názvem Group, která obsahuje pole s názvem Employees , které vrací pole Employee objektů. Příklad odvozuje Manager třídu z Employee třídy a použije na XmlIncludeAttributeEmployee třídu . Když příklad vytvoří Group objekt, vloží Manager objekt do Employee pole. Nakonec příklad serializuje Group objekt.
