SoapElementAttribute Class


Specifies that the public member value be serialized by the XmlSerializer as an encoded SOAP XML element.

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


[<AttributeUsageAttribute(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter | AttributeTargets.ReturnValue)>]
type SoapElementAttribute = 
        inherit Attribute


Initializes a new instance of the SoapElementAttribute class.


Initializes a new instance of the SoapElementAttribute class and specifies the name of the XML element.


Gets or sets the XML Schema definition language (XSD) data type of the generated XML element.


Gets or sets the name of the generated XML element.


Gets or sets a value that indicates whether the XmlSerializer must serialize a member that has the xsi:null attribute set to "1".


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The SoapElementAttribute 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 ( 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.

Apply the SoapElementAttribute to a public field to direct the XmlSerializer to serialize the field as an encoded SOAP XML element.

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

The following example serializes an instance of a class named Transportation that contains a field named Vehicle. A SoapElementAttribute is applied to the field. When the field is serialized, the XML element name is "Wheels" instead of "Vehicle". The SerializeOverride method creates a SoapElementAttribute and sets the SoapElement property of a SoapAttributes to the SoapElementAttribute. The SoapAttributes is added to a SoapAttributeOverrides that is used to create an XmlTypeMapping. An XmlSerializer is constructed with the XmlTypeMapping, and an instance of the Transportation class is again serialized. Because the SoapElementAttribute is used to override the serialization, the generated XML element name is now "Truck" instead of "Wheels".
