XmlSchemaType.IsDerivedFrom Method

Definition

Returns a value indicating if the derived schema type specified is derived from the base schema type specified.

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);
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

Parameters

derivedType
XmlSchemaType

The derived XmlSchemaType to test.

baseType
XmlSchemaType

The base XmlSchemaType to test the derived XmlSchemaType against.

except
XmlSchemaDerivationMethod

One of the XmlSchemaDerivationMethod values representing a type derivation method to exclude from testing.

Returns

true if the derived type is derived from the base type; otherwise, false.

Examples

The following is an example of the IsDerivedFrom method.

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))
