System.Xml.Schema.XmlSchemaAppInfo Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema
Summary
Defines application specific information within an annotation. Represents the World Wide Web Consortium (W3C) appinfo element.
C# Syntax:
public class XmlSchemaAppInfo : XmlSchemaObject
Example
The following example creates an AppInfo element.
using System;
using System.Xml;  
using System.Xml.Schema;

class XMLSchemaExamples {
    public static void Main() {
 
        XmlSchema schema = new XmlSchema();
        
        // <xs:element name="State">
        XmlSchemaElement element = new XmlSchemaElement();
        schema.Items.Add(element);
        element.Name = "State";

        // <xs:annotation>
        XmlSchemaAnnotation annNorthwestStates = new XmlSchemaAnnotation();
        element.Annotation = annNorthwestStates;

        // <xs:documentation>State Name</xs:documentation>
        XmlSchemaDocumentation docNorthwestStates = new XmlSchemaDocumentation();
        annNorthwestStates.Items.Add(docNorthwestStates);
        docNorthwestStates.Markup = TextToNodeArray("State Name");

        // <xs:appInfo>Application Information</xs:appInfo>
        XmlSchemaAppInfo appInfo = new XmlSchemaAppInfo();
        annNorthwestStates.Items.Add(appInfo);
        appInfo.Markup = TextToNodeArray("Application Information");

        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);
    }

    public static XmlNode[] TextToNodeArray(string text) {
        XmlDocument doc = new XmlDocument();
        return new XmlNode[1] {doc.CreateTextNode(text)};
    }
}

    

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


<?xml version="1.0" encoding="IBM437"?>
<xs:schema  xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="State">
        <xs:annotation>
            <xs:documentation>State Name</xs:documentation>            
            <xs:appinfo>Application Information</xs:appinfo>
        </xs:annotation>
    </xs:element>
</xs:schema>
