XmlSchemaComplexType Class

Class for complex types. Defines a complex type that determines the set of attributes and content of an element. Represents the World Wide Web Consortium (W3C) complexType element.

For a list of all members of this type, see XmlSchemaComplexType Members.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


An element can be declared with a type attribute that refers to a complexType element that defines the structure, content, and attributes of that element.


[Visual Basic, C#, C++] The following example creates a complexType element.

[Visual Basic] 
Imports System
Imports System.Xml  
Imports System.Xml.Schema

Class XMLSchemaExamples 
    Public Shared Sub Main()

        Dim schema as New XmlSchema()

        ' <xs:element name="stringElementWithAnyAttribute">
        Dim element as New XmlSchemaElement()
        element.Name = "stringElementWithAnyAttribute"
        ' <xs:complexType>
        Dim complexType as New XmlSchemaComplexType()
        element.SchemaType = complexType
                ' <xs:simpleContent>
        Dim simpleContent as New XmlSchemaSimpleContent()
        complexType.ContentModel = simpleContent

        Dim extension as New XmlSchemaSimpleContentExtension()

[Visual Basic, C#, C++] The following XML file is used for the preceding code example.

<?xml version="1.0" encoding="IBM437"?>
<xs:schema xmlns:xs="">
    <xs:element name="stringElementWithAnyAttribute">
                <xs:extension base="xs:string">
                    <xs:anyAttribute namespace="##targetNamespace"/>
