XamlType.LookupConstructionRequiresArguments Method

Definition

Namespace:

System.Xaml

Assembly:

System.Xaml.dll

Returns a value that indicates whether this XamlType must have arguments (generic constraints through x:TypeArguments, initialization text, or other XAML techniques) to construct a valid instance of the type.

protected:
 virtual bool LookupConstructionRequiresArguments();

protected virtual bool LookupConstructionRequiresArguments ();

abstract member LookupConstructionRequiresArguments : unit -> bool
override this.LookupConstructionRequiresArguments : unit -> bool

Protected Overridable Function LookupConstructionRequiresArguments () As Boolean

Returns

Boolean

true if construction of an instance requires some argument value; otherwise, false.

Remarks

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

The default implementation returns false for types considered value types in the CLR type system. For other than value types, CLR reflection ConstructorInfo is used to determine whether a parameterless constructor exists.

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.
