XmlSchemaMinLengthFacet 类

定义

按 WWW 联合会 (W3C) 指定的方式显示 minLength 来自 XML 架构的元素。Represents the minLength element from XML Schema as specified by the World Wide Web Consortium (W3C). 此类可以用来指定 simpleType 元素的数据值的最小长度限制。This class can be used to specify a restriction on the minimum length of the data value of a simpleType element. 该长度必须大于 minLength 元素的值。The length must be greater than the value of the minLength element.

public class XmlSchemaMinLengthFacet : System.Xml.Schema.XmlSchemaNumericFacet
type XmlSchemaMinLengthFacet = class

示例

下面的示例演示如何使用 XmlSchemaMinLengthFacet 类。The following example shows the use of the XmlSchemaMinLengthFacet class.

#using <System.Xml.dll>

为此代码示例生成以下 XML 文件。The following XML file is generated for this code example.

<?xml version="1.0" encoding="IBM437"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:simpleType name="ZipCodeType">
        <xs:restriction base="xs:string">
            <xs:minLength value="5"/>
        </xs:restriction>
    </xs:simpleType>

    <xs:element name="Address">
        <xs:complexType>
            <xs:attribute name="ZipCode" type="ZipCodeType"/>
        </xs:complexType>
    </xs:element>
</xs:schema>
