System.Xml.Schema.XmlSchemaComplexContent Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema
Summary
Class that represents the complex content model for complex types. Contains extensions or restrictions on a complex type that has mixed content or elements only. Represents the World Wide Web Consortium (W3C) complexContent element.
C# Syntax:
public class XmlSchemaComplexContent : XmlSchemaContentModel
Example
The following example creates a complexContent element.
using System;
using System.Xml;  
using System.Xml.Schema;

        // <xs:sequence>
        XmlSchemaSequence sequence2 = new XmlSchemaSequence();
        extensionAddress.Particle = sequence2;
        
        // <xs:element name="state" type="xs:string"/>
        XmlSchemaElement elementUSState = new XmlSchemaElement();

        schema.Compile(new ValidationEventHandler(ValidationCallbackOne));
        XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
        nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
        schema.Write(Console.Out, nsmgr);
    }

    public static void ValidationCallbackOne(object sender, ValidationEventArgs args) {

        Console.WriteLine(args.Message);
    }
}
