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

Boolean

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))
