The SoapEnumAttribute type exposes the following members.

Constructors
  NameDescription
Public method Supported by the XNA Framework SoapEnumAttributeInitializes a new instance of the SoapEnumAttribute class.
Public method Supported by the XNA Framework SoapEnumAttribute(String)Initializes a new instance of the SoapEnumAttribute class using the specified element name.

Properties
  NameDescription
Public property Supported by the XNA Framework NameGets or sets the value generated in an XML document when the XmlSerializer serializes an enumeration, or the value recognized when it deserializes the enumeration member.
Public property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
Methods
  NameDescription
Public method Supported by the XNA Framework EqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected method Supported by the XNA Framework FinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method Supported by the XNA Framework GetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public method Supported by the XNA Framework GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method Supported by the XNA Framework MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected method Supported by the XNA Framework MemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public method Supported by the XNA Framework ToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations
  NameDescription
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

The SoapEnumAttribute class belongs to a family of attributes that controls how the XmlSerializer serializes or deserializes an object as encoded SOAP XML. The resulting XML conforms to section 5 of the World Wide Web Consortium (www.w3.org) document "Simple Object Access Protocol (SOAP) 1.1". For a complete list of similar attributes, see Attributes That Control Encoded SOAP Serialization.

To serialize an object as an encoded SOAP message, you must construct the XmlSerializer using an XmlTypeMapping created with the ImportTypeMapping method of the SoapReflectionImporter class.

Use the SoapEnumAttribute to change the enumeration that the XmlSerializer generates or recognizes (when it serializes or deserializes a class, respectively). For example, if an enumeration contains a member named One, but you prefer that the XML output be named Single, apply the SoapEnumAttribute to the enumeration member and set the Name property to "Single".

You can override the Name property value of a SoapEnumAttribute by creating an instance of the SoapEnumAttribute class and assigning it to the SoapEnum property of a SoapAttributes. For details, see the SoapAttributeOverrides class overview.

To serialize an object as an encoded SOAP message, you must construct the XmlSerializer using an XmlTypeMapping created with the ImportTypeMapping method of the SoapReflectionImporter class.

NoteNote

You can use the word SoapEnum in your code instead of the longer SoapEnumAttribute.

For more information about using attributes, see Extending Metadata Using Attributes.

Examples

The following example uses the XmlSerializer to serialize a class named Food that includes an enumeration named FoodType. The FoodType enumeration is overridden by creating a SoapEnumAttribute for each enumeration and setting the SoapEnum property of a SoapAttributes to the SoapEnumAttribute. The SoapAttributes is added to a SoapAttributeOverrides that is used to create an XmlSerializer.
