SoapIncludeAttribute Class

Definition

Allows the XmlSerializer to recognize a type when it serializes or deserializes an object as encoded SOAP XML.

public ref class SoapIncludeAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true)]
public class SoapIncludeAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true)]
public class SoapIncludeAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true)>]
type SoapIncludeAttribute = class
    inherit Attribute
[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true)>]
type SoapIncludeAttribute = class
    inherit Attribute

Examples

The following example applies the SoapIncludeAttribute twice to an XML Web service method. The method returns an object of type Vehicle (a base class). The SoapIncludeAttribute allows the method to return instances of classes derived from the Vehicle class.

Remarks

The SoapIncludeAttribute 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.

When applying the SoapIncludeAttribute, specify the Type of the derived class. When the XmlSerializer serializes objects that include both the base and the derived classes, it can then recognize both object types.

You can use the SoapIncludeAttribute to include derived classes in service description documents that are written in the Web Services Description Language (WSDL). For example, if a method returns an Object, apply the SoapIncludeAttribute to the method and specify the actual types that should be returned.

For more information about WSDL, see World Wide Web Consortium specification, Web Services Description Language (WSDL) 1.1.

Constructors

SoapIncludeAttribute(Type)

Initializes a new instance of the SoapIncludeAttribute class using the specified type.

Properties

Type

Gets or sets the type of the object to use when serializing or deserializing an object.

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.

Methods

Equals(Object)

Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)
GetHashCode()

Returns the hash code for this instance.

(Inherited from Attribute)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
IsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)
Match(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(Inherited from Attribute)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()

Returns a string that represents the current object.

Explicit Interface Implementations

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

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_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)
_Attribute.GetTypeInfoCount(UInt32)

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

(Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.
