XmlSchemaComplexContent Class
.NET Framework 3.0
Represents the complexContent element from XML Schema as specified by the . This class represents the complex content model for complex types. It contains extensions or restrictions on a complex type that has either only elements or mixed content.
Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)
Assembly: System.Xml (in system.xml.dll)
The following example creates a complexContent element.
using System; using System.Xml; using System.Xml.Schema; class XMLSchemaExamples { public static void Main() { XmlSchema schema = new XmlSchema(); // <xs:complexType name="address"> XmlSchemaComplexType address = new XmlSchemaComplexType(); schema.Items.Add(address); address.Name = "address"; // <xs:sequence> XmlSchemaSequence sequence = new XmlSchemaSequence(); address.Particle = sequence; // <xs:element name="name" type="xs:string"/> XmlSchemaElement elementName = new XmlSchemaElement(); sequence.Items.Add(elementName); elementName.Name = "name"; elementName.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema"); // <xs:element name="street" type="xs:string"/> XmlSchemaElement elementStreet = new XmlSchemaElement(); sequence.Items.Add(elementStreet); elementStreet.Name = "street"; elementStreet.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema"); // <xs:element name="city" type="xs:string"/> XmlSchemaElement elementCity = new XmlSchemaElement(); sequence.Items.Add(elementCity); elementCity.Name = "city"; elementCity.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema"); // <xs:complexType name="USAddress"> XmlSchemaComplexType USAddress = new XmlSchemaComplexType(); schema.Items.Add(USAddress); USAddress.Name = "USAddress"; // <xs:complexContent> XmlSchemaComplexContent complexContent = new XmlSchemaComplexContent(); USAddress.ContentModel = complexContent; // <xs:extension base="address"> XmlSchemaComplexContentExtension extensionAddress = new XmlSchemaComplexContentExtension(); complexContent.Content = extensionAddress; extensionAddress.BaseTypeName = new XmlQualifiedName("address"); // <xs:sequence> XmlSchemaSequence sequence2 = new XmlSchemaSequence(); extensionAddress.Particle = sequence2; // <xs:element name="state" type="xs:string"/> XmlSchemaElement elementUSState = new XmlSchemaElement(); sequence2.Items.Add(elementUSState); elementUSState.Name = "state"; elementUSState.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema"); // <xs:element name="zipcode" type="xs:positiveInteger"/> XmlSchemaElement elementZipcode = new XmlSchemaElement(); sequence2.Items.Add(elementZipcode); elementZipcode.Name = "zipcode"; elementZipcode.SchemaTypeName = new XmlQualifiedName("positiveInteger", "http://www.w3.org/2001/XMLSchema"); XmlSchemaSet schemaSet = new XmlSchemaSet(); schemaSet.ValidationEventHandler += new ValidationEventHandler(ValidationCallbackOne); schemaSet.Add(schema); schemaSet.Compile(); XmlSchema compiledSchema = null; foreach (XmlSchema schema1 in schemaSet.Schemas()) { compiledSchema = schema1; } XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable()); nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema"); compiledSchema.Write(Console.Out, nsmgr); } public static void ValidationCallbackOne(object sender, ValidationEventArgs args) { Console.WriteLine(args.Message); } }
