XamlType.LookupKeyType Method

Returns a value that provides the type information for the key property of this XamlType, if the XamlType represents a dictionary.

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

protected virtual XamlType LookupKeyType()

Return Value

Type: System.Xaml.XamlType
A XamlType object for the type of the key for dictionary usage, or null if this XamlType does not represent a dictionary,

This method can be invoked by calls to KeyType.

The default implementation can use CLR reflection concepts, such as checking for an Add method by MethodInfo and using the ParameterInfo; and checking BaseType and trying the same logic there.

Override this method if you want KeyType to use different logic. Cases where LookupCollectionKind does not return XamlCollectionKind.Dictionary should return null.
