LookupBaseType Method

XamlType.LookupBaseType Method

.NET Framework 4.6 and 4.5

Returns the XamlType for the immediate base type of this XAML type. Determination of this value is based on the underlying type of this XamlType and schema context.

Namespace:  System.Xaml
Assembly:  System.Xaml (in System.Xaml.dll)

protected virtual XamlType LookupBaseType()

Return Value

Type: System.Xaml.XamlType
The XamlType for the immediate base type of this XAML type.

This method can be invoked when a caller gets a value from BaseType.

The default implementation might return an internal constant that represents the Object if UnderlyingType is null.

Override this method if you are not relying on default internal CLR reflection and are using metadata or other techniques for reporting the XAML type system information or schema information of a type.

Security noteSecurity Note

LookupBaseType is virtual, and therefore, can be overridden. The override has the potential (whether for malicious purposes or otherwise) to change the reported type information about a XAML type so that it no longer aligns in an expected way with the type system information of its underlying CLR type. For any security-critical checks of assignment operations and access, use the underlying CLR type instead.
