XmlSchemaSimpleContent Class

Represents the simpleContent element from XML Schema as specified by the World Wide Web Consortium (W3C). This class is for simple and complex types with simple content model.

Namespace:  System.Xml.Schema
Assembly:  System.Xml (in System.Xml.dll)

public class XmlSchemaSimpleContent : XmlSchemaContentModel

XmlSchemaSimpleContent is used to indicate that the content model of the new type contains only character data and no elements. It does this through XmlSchemaSimpleContentExtension or XmlSchemaSimpleContentRestriction.

The following example shows the XmlSchemaSimpleContent class.

using System;
using System.Xml;
using System.Xml.Schema;

class XMLSchemaExamples
    public static void Main()

        XmlSchema schema = new XmlSchema();

        // <xs:element name="generalPrice">
        XmlSchemaElement generalPrice = new XmlSchemaElement();
        generalPrice.Name = "generalPrice";

        // <xs:complexType>
        XmlSchemaComplexType ct = new XmlSchemaComplexType();

        // <xs:simpleContent>
        XmlSchemaSimpleContent simpleContent = new XmlSchemaSimpleContent();

        // <xs:extension base="xs:decimal">
        XmlSchemaSimpleContentExtension simpleContent_extension = new XmlSchemaSimpleContentExtension();
        simpleContent_extension.BaseTypeName = new XmlQualifiedName("decimal", "");

        // <xs:attribute name="currency" type="xs:string" />
        XmlSchemaAttribute currency = new XmlSchemaAttribute();
        currency.Name = "currency";
        currency.SchemaTypeName = new XmlQualifiedName("string", "");

        simpleContent.Content = simpleContent_extension;
        ct.ContentModel = simpleContent;
        generalPrice.SchemaType = ct;


        XmlSchemaSet schemaSet = new XmlSchemaSet();
        schemaSet.ValidationEventHandler += new ValidationEventHandler(ValidationCallbackOne);

        XmlSchema compiledSchema = null;

        foreach (XmlSchema schema1 in schemaSet.Schemas())
            compiledSchema = schema1;

        XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
        nsmgr.AddNamespace("xs", "");
        compiledSchema.Write(Console.Out, nsmgr);

    public static void ValidationCallbackOne(object sender, ValidationEventArgs args)


The following XML file is generated for the preceding code example.

<?xml version="1.0" encoding="IBM437"?>
<xs:schema  xmlns:xs="">
    <xs:element name="generalPrice">
          <xs:extension base="xs:decimal">
            <xs:attribute name="currency" type="xs:string" />
