Change |
Converts the value specified, whose type is one of the valid Common Language Runtime (CLR) representations of the XML schema type represented by the XmlSchemaDatatype, to the CLR type specified using the IXmlNamespaceResolver if the XmlSchemaDatatype represents the xs:QName type or a type derived from it. |
