XmlSchemaComplexContentRestriction Class
.NET Framework 3.0
Represents the restriction element from XML Schema as specified by the . This class is for complex types with a complex content model derived by restriction. It restricts the contents of the complex type to a subset of the inherited complex type.
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 extended by restriction.
using System; using System.Xml; using System.Xml.Schema; class XMLSchemaExamples { public static void Main() { XmlSchema schema = new XmlSchema(); // <xs:complexType name="phoneNumber"> XmlSchemaComplexType phoneNumber = new XmlSchemaComplexType(); phoneNumber.Name = "phoneNumber"; // <xs:sequence> XmlSchemaSequence phoneNumberSequence = new XmlSchemaSequence(); // <xs:element name="areaCode"/> XmlSchemaElement areaCode1 = new XmlSchemaElement(); areaCode1.MinOccurs = 0; areaCode1.MaxOccursString = "1"; areaCode1.Name = "areaCode"; phoneNumberSequence.Items.Add(areaCode1); // <xs:element name="prefix"/> XmlSchemaElement prefix1 = new XmlSchemaElement(); prefix1.MinOccurs = 1; prefix1.MaxOccursString = "1"; prefix1.Name = "prefix"; phoneNumberSequence.Items.Add(prefix1); // <xs:element name="number"/> XmlSchemaElement number1 = new XmlSchemaElement(); number1.MinOccurs = 1; number1.MaxOccursString = "1"; number1.Name = "number"; phoneNumberSequence.Items.Add(number1); phoneNumber.Particle = phoneNumberSequence; schema.Items.Add(phoneNumber); // <xs:complexType name="localPhoneNumber"> XmlSchemaComplexType localPhoneNumber = new XmlSchemaComplexType(); localPhoneNumber.Name = "localPhoneNumber"; // <xs:complexContent> XmlSchemaComplexContent complexContent = new XmlSchemaComplexContent(); // <xs:restriction base="phoneNumber"> XmlSchemaComplexContentRestriction restriction = new XmlSchemaComplexContentRestriction(); restriction.BaseTypeName = new XmlQualifiedName("phoneNumber", ""); // <xs:sequence> XmlSchemaSequence sequence2 = new XmlSchemaSequence(); // <xs:element name="areaCode" minOccurs="0"/> XmlSchemaElement areaCode2 = new XmlSchemaElement(); areaCode2.MinOccurs = 0; areaCode2.MaxOccursString = "1"; areaCode2.Name = "areaCode"; sequence2.Items.Add(areaCode2); // <xs:element name="prefix"/> XmlSchemaElement prefix2 = new XmlSchemaElement(); prefix2.MinOccurs = 1; prefix2.MaxOccursString = "1"; prefix2.Name = "prefix"; sequence2.Items.Add(prefix2); // <xs:element name="number"/> XmlSchemaElement number2 = new XmlSchemaElement(); number2.MinOccurs = 1; number2.MaxOccursString = "1"; number2.Name = "number"; sequence2.Items.Add(number2); restriction.Particle = sequence2; complexContent.Content = restriction; localPhoneNumber.ContentModel = complexContent; schema.Items.Add(localPhoneNumber); 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); } }
