示例

以下示例创建 一个 appinfo 元素。

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");

        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);
    }

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

Imports System.Xml

Class XMLSchemaExamples
    Public Shared Sub Main()
        Dim schema As New XmlSchema()

        ' <xs:element name="State">
        Dim element As New XmlSchemaElement()
        schema.Items.Add(element)
        element.Name = "State"

        ' <xs:annotation>
        Dim annNorthwestStates As New XmlSchemaAnnotation()
        element.Annotation = annNorthwestStates

        ' <xs:documentation>State Name</xs:documentation>
        Dim docNorthwestStates As New XmlSchemaDocumentation()
        annNorthwestStates.Items.Add(docNorthwestStates)
        docNorthwestStates.Markup = TextToNodeArray("State Name")

        ' <xs:appInfo>Application Information</xs:appInfo>
        Dim appInfo As New XmlSchemaAppInfo()
        annNorthwestStates.Items.Add(appInfo)
        appInfo.Markup = TextToNodeArray("Application Information")

        Dim schemaSet As New XmlSchemaSet()
        AddHandler schemaSet.ValidationEventHandler, AddressOf ValidationCallbackOne

        schemaSet.Add(schema)
        schemaSet.Compile()

        Dim compiledSchema As XmlSchema = Nothing

        For Each schema1 As XmlSchema In schemaSet.Schemas()
            compiledSchema = schema1
        Next

        Dim nsmgr As New XmlNamespaceManager(New NameTable())
        nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema")
        compiledSchema.Write(Console.Out, nsmgr)
    End Sub


    Public Shared Sub ValidationCallbackOne(ByVal sender As Object, ByVal args As ValidationEventArgs)

        Console.WriteLine(args.Message)
    End Sub


    Public Shared Function TextToNodeArray(ByVal text As String) As XmlNode()
        Dim doc As New XmlDocument()
        Return New XmlNode(0) {doc.CreateTextNode(text)}
    End Function 'TextToNodeArray
End Class

为前面的代码示例生成以下 XML 文件。

<?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>

元素 appinfo 定义批注中特定于应用程序的信息
