XmlSchemaSimpleContent 类

定义

按 WWW 联合会 (W3C) 指定的方式显示 simpleContent 来自 XML 架构的元素。 此类用于具有简单内容模型的简单和复杂类型。

public ref class XmlSchemaSimpleContent : System::Xml::Schema::XmlSchemaContentModel
public class XmlSchemaSimpleContent : System.Xml.Schema.XmlSchemaContentModel
type XmlSchemaSimpleContent = class
    inherit XmlSchemaContentModel
Public Class XmlSchemaSimpleContent
Inherits XmlSchemaContentModel
继承

示例

下面的示例展示了 XmlSchemaSimpleContent 类。

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>
