示例

下面的示例演示了该 XmlSchemaSimpleContent 类。

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", "http://www.w3.org/2001/XMLSchema");

        // <xs:attribute name="currency" type="xs:string" />
        XmlSchemaAttribute currency = new XmlSchemaAttribute();
        currency.Name = "currency";
        currency.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");
        simpleContent_extension.Attributes.Add(currency);

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

        schema.Items.Add(generalPrice);

        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);
    }
}

Class XMLSchemaExamples

    Public Shared Sub Main()

        Dim schema As New XmlSchema()

        ' <xs:element name="generalPrice">
        Dim generalPrice As New XmlSchemaElement()
        generalPrice.Name = "generalPrice"

        ' <xs:complexType>
        Dim ct As New XmlSchemaComplexType()

        ' <xs:simpleContent>
        Dim simpleContent As New XmlSchemaSimpleContent()

        ' <xs:extension base="xs:decimal">
        Dim simpleContent_extension As New XmlSchemaSimpleContentExtension()
        simpleContent_extension.BaseTypeName = New XmlQualifiedName("decimal", "http://www.w3.org/2001/XMLSchema")

        ' <xs:attribute name="currency" type="xs:string" />
        Dim currency As New XmlSchemaAttribute()
        currency.Name = "currency"
        currency.SchemaTypeName = New XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema")
        simpleContent_extension.Attributes.Add(currency)

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

        schema.Items.Add(generalPrice)

        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:element name="generalPrice">
      <xs:complexType>
        <xs:simpleContent>
          <xs:extension base="xs:decimal">
            <xs:attribute name="currency" type="xs:string" />
          </xs:extension>
        </xs:simpleContent>
      </xs:complexType>
    </xs:element>
</xs:schema>

注解

XmlSchemaSimpleContent 用于指示新类型的内容模型仅包含字符数据，且不包含任何元素。 它通过 XmlSchemaSimpleContentExtension 或 XmlSchemaSimpleContentRestriction执行此操作。
