public class SoapTypeAttribute : Attribute

NameDescription
System_CAPS_pubmethodSoapTypeAttribute()

Initializes a new instance of the SoapTypeAttribute class.

System_CAPS_pubmethodSoapTypeAttribute(String)

Initializes a new instance of the SoapTypeAttribute class and specifies the name of the XML type.

System_CAPS_pubmethodSoapTypeAttribute(String, String)

Initializes a new instance of the SoapTypeAttribute class and specifies the name and XML namespace of the type.

NameDescription
System_CAPS_pubpropertyIncludeInSchema

Gets or sets a value that indicates whether to include the type in SOAP-encoded XML Schema documents.

System_CAPS_pubpropertyNamespace

Gets or sets the namespace of the XML type.

System_CAPS_pubpropertyTypeId

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

System_CAPS_pubpropertyTypeName

Gets or sets the name of the XML type.

NameDescription
System_CAPS_pubmethodEquals(Object)

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.)

System_CAPS_protmethodFinalize()

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

System_CAPS_pubmethodGetHashCode()

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

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodIsDefaultAttribute()

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

System_CAPS_pubmethodMatch(Object)

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

System_CAPS_protmethodMemberwiseClone()

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

System_CAPS_pubmethodToString()

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

NameDescription
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.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

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 SoapTypeAttribute 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, construct the XmlSerializer using an XmlTypeMapping created with the ImportTypeMapping method of the SoapReflectionImporter class.

The SoapTypeAttribute can only be applied to class declarations.

The IncludeInSchema property determines whether the resulting XML element type is included in the XML Schema document (.xsd) for the generated XML stream. To see the schema, compile the class into a DLL file. Pass the resulting file as an argument to the XML Schema Definition Tool (Xsd.exe). The tool generates the XML Schema for the XML stream generated when the class is serialized by an instance of the XmlSerializer class.

Setting a different namespace causes Xsd.exe to write a different schema (.xsd) file for the XML stream generated when the class is serialized.

The following example serializes a class named Group. The SoapTypeAttribute is applied to the class, with the TypeName set to "SoapGroupType". The SoapTypeAttribute is also overridden, changing the TypeName to "Team". Both versions are serialized, resulting in two files: SoapType.xml and SoapType2.xml.
