以下示例演示类 XmlSchemaFractionDigitsFacet 的使用。

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

class XMLSchemaExamples
{
    public static void Main()
    {

        XmlSchema schema = new XmlSchema();

        // <xs:simpleType name="RatingType">
        XmlSchemaSimpleType RatingType = new XmlSchemaSimpleType();
        RatingType.Name = "RatingType";

        // <xs:restriction base="xs:number">
        XmlSchemaSimpleTypeRestriction restriction = new XmlSchemaSimpleTypeRestriction();
        restriction.BaseTypeName = new XmlQualifiedName("decimal", "http://www.w3.org/2001/XMLSchema");

        // <xs:totalDigits value="2"/>
        XmlSchemaTotalDigitsFacet totalDigits = new XmlSchemaTotalDigitsFacet();
        totalDigits.Value = "2";
        restriction.Facets.Add(totalDigits);

        // <xs:fractionDigits value="1"/>
        XmlSchemaFractionDigitsFacet fractionDigits = new XmlSchemaFractionDigitsFacet();
        fractionDigits.Value = "1";
        restriction.Facets.Add(fractionDigits);

        RatingType.Content = restriction;

        schema.Items.Add(RatingType);

        // <xs:element name="movie">
        XmlSchemaElement element = new XmlSchemaElement();

        ratingAttribute.SchemaTypeName = new XmlQualifiedName("RatingType", "");
        complexType.Attributes.Add(ratingAttribute);

        element.SchemaType = complexType;

        schema.Items.Add(element);

        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);
    }
}

Imports System.Xml
Imports System.Xml.Schema

Class XMLSchemaExamples
    Public Shared Sub Main()

        Dim schema As New XmlSchema()

        '<xs:simpleType name="RatingType">

        Dim totalDigits As New XmlSchemaTotalDigitsFacet()
        totalDigits.Value = "2"
        restriction.Facets.Add(totalDigits)

        Dim fractionDigits As New XmlSchemaFractionDigitsFacet()

        element.SchemaType = complexType

        schema.Items.Add(element)

        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
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:simpleType name="RatingType">
        <xs:restriction base="xs:decimal">
            <xs:totalDigits value="2"/>
            <xs:fractionDigits value="1"/>
        </xs:restriction>
    </xs:simpleType>

    <xs:element name="movie">
        <xs:complexType>
            <xs:attribute name="rating" type="RatingType"/>
        </xs:complexType>
    </xs:element>

</xs:schema>
