SoapTypeAttribute Class

Controls the schema generated by the XmlSerializer when a class instance is serialized as SOAP encoded XML.

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

[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface)] 
public class SoapTypeAttribute : Attribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface) */ 
public class SoapTypeAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface) 
public class SoapTypeAttribute extends 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.
