XamlType.LookupKeyType Method

  • Reference

Definition

Namespace:
System.Xaml
Assembly:
System.Xaml.dll

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

protected:
 virtual System::Xaml::XamlType ^ LookupKeyType();
protected virtual System.Xaml.XamlType LookupKeyType ();
abstract member LookupKeyType : unit -> System.Xaml.XamlType
override this.LookupKeyType : unit -> System.Xaml.XamlType
Protected Overridable Function LookupKeyType () As XamlType

Returns

XamlType

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

Remarks

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.
