SoapAttributes.SoapEnum Property

Gets or sets an object that specifies how the XmlSerializer serializes a SOAP enumeration.

Namespace: System.Xml.Serialization
Assembly: System.Xml (in system.xml.dll)

public SoapEnumAttribute SoapEnum { get; set; }
/** @property */
public SoapEnumAttribute get_SoapEnum ()

/** @property */
public void set_SoapEnum (SoapEnumAttribute value)

public function get SoapEnum () : SoapEnumAttribute

public function set SoapEnum (value : SoapEnumAttribute)

Not applicable.

Property Value

A SoapEnumAttribute.

The SoapEnumAttribute is used to control the serialization of an enumeration member. Set the SoapEnum property to a new SoapEnumAttribute to override the serialization of such a member.

For more information, see the SoapAttributeOverrides class overview.

The following example serializes two classes named Food and FoodType. The FoodType class contains two enumerations that are overridden, and for each enumeration, the example creates a SoapEnumAttribute that it assigns to the SoapEnum property of a SoapAttributes. The example then adds the SoapAttributes to a SoapAttributeOverrides, which is used to create an XmlSerializer.
