XmlSchemaType.IsDerivedFrom Método

Definição

Namespace:
System.Xml.Schema
Assembly:
System.Xml.dll
Assembly:
netstandard.dll

Retorna um valor que indica se o tipo de esquema derivado especificado é derivado do tipo de esquema base especificado.

public:
 static bool IsDerivedFrom(System::Xml::Schema::XmlSchemaType ^ derivedType, System::Xml::Schema::XmlSchemaType ^ baseType, System::Xml::Schema::XmlSchemaDerivationMethod except);
public static bool IsDerivedFrom(System.Xml.Schema.XmlSchemaType derivedType, System.Xml.Schema.XmlSchemaType baseType, System.Xml.Schema.XmlSchemaDerivationMethod except);
static member IsDerivedFrom : System.Xml.Schema.XmlSchemaType * System.Xml.Schema.XmlSchemaType * System.Xml.Schema.XmlSchemaDerivationMethod -> bool
Public Shared Function IsDerivedFrom (derivedType As XmlSchemaType, baseType As XmlSchemaType, except As XmlSchemaDerivationMethod) As Boolean

Parâmetros

derivedType
XmlSchemaType

O derivado XmlSchemaType para teste.

baseType
XmlSchemaType

A base XmlSchemaType na qual testar o derivado XmlSchemaType .

except
XmlSchemaDerivationMethod

Um dos XmlSchemaDerivationMethod valores que representam um método de derivação de tipo a ser excluído do teste.

Retornos

Boolean

true se o tipo derivado for derivado do tipo base; caso contrário, false.

Exemplos

Veja a seguir um exemplo do IsDerivedFrom método.

XmlSchemaType xsdInteger = XmlSchemaType.GetBuiltInSimpleType(XmlTypeCode.Integer);
XmlSchemaType xsdPositiveInteger = XmlSchemaType.GetBuiltInSimpleType(XmlTypeCode.PositiveInteger);

// true
Console.WriteLine(XmlSchemaType.IsDerivedFrom(xsdPositiveInteger, xsdInteger, XmlSchemaDerivationMethod.None));

// false
Console.WriteLine(XmlSchemaType.IsDerivedFrom(xsdPositiveInteger, xsdInteger, XmlSchemaDerivationMethod.Restriction));

Dim xsdInteger As XmlSchemaType = XmlSchemaType.GetBuiltInSimpleType(XmlTypeCode.Integer)
Dim xsdPositiveInteger As XmlSchemaType = XmlSchemaType.GetBuiltInSimpleType(XmlTypeCode.PositiveInteger)

' True
Console.WriteLine(XmlSchemaType.IsDerivedFrom(xsdPositiveInteger, xsdInteger, XmlSchemaDerivationMethod.None))

' False
Console.WriteLine(XmlSchemaType.IsDerivedFrom(xsdPositiveInteger, xsdInteger, XmlSchemaDerivationMethod.Restriction))
