XmlSchemaMaxInclusiveFacet クラス

W3C (World Wide Web Consortium) で指定された XML スキーマの maxInclusive 要素を表します。このクラスを使用すると、simpleType 要素の最大値に制限を設定できます。要素の値は maxInclusive 要素の値以下である必要があります。

名前空間: System.Xml.Schema
アセンブリ: System.Xml (system.xml.dll 内)
構文

Visual Basic (宣言)

Public Class XmlSchemaMaxInclusiveFacet
    Inherits XmlSchemaFacet

Visual Basic (使用法)

Dim instance As XmlSchemaMaxInclusiveFacet

public class XmlSchemaMaxInclusiveFacet : XmlSchemaFacet

C++

public ref class XmlSchemaMaxInclusiveFacet
 : public XmlSchemaFacet

public class XmlSchemaMaxInclusiveFacet extends
 XmlSchemaFacet

JScript

public class XmlSchemaMaxInclusiveFacet extends
 XmlSchemaFacet

使用例

XmlSchemaMaxInclusiveFacet クラスを使用する例を次に示します。
