Binder Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Selects a member from a list of candidates, and performs type conversion from actual argument type to formal argument type.

Syntax

C++

No code example is currently available or this language may not be supported.

The Binder type exposes the following members.

	Name	Description
	Binder	Initializes a new instance of the Binder class.

	Name	Description
	BindToField	Selects a field from the given set of fields, based on the specified criteria.
	BindToMethod	Selects a method to invoke from the given set of methods, based on the supplied arguments.
	ChangeType	Changes the type of the given Object to the given Type.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReorderArgumentArray	Upon returning from BindToMethod, restores the args argument to what it was when it came from BindToMethod.
	SelectMethod	Selects a method from the given set of methods, based on the argument type.
	SelectProperty	Selects a property from the given set of properties, based on the specified criteria.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Implementations of the Binder class are used by methods such as Type::InvokeMember, which selects from a set of possible members to execute, based on a set of parameter types and argument values; Type::GetMethod, which selects a method based on parameter types; and so on.

A default implementation of the Binder class is provided by the Type::DefaultBinder property.

Notes to Inheritors

When you inherit from Binder, you must override the following members: BindToMethod, BindToField, ReorderArgumentArray, SelectMethod, SelectProperty, and ChangeType.

Examples

The following example implements and demonstrates all members of the Binder class. The private method CanConvertFrom finds compatible types for a given type.
