Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Enables JScript to communicate with an external COM field. This class is used by an external COM implementation to expose its objects to JScript because JScript needs a managed MemberInfo in order to bind to an external object.

This API supports the product infrastructure and is not intended to be used directly from your code.

Module	Gets the module in which the type that declares the member represented by the current MemberInfo is defined. (Inherited from MemberInfo)
Name	This API supports the product infrastructure and is not intended to be used directly from your code. Gets the name of the external COM field that this object represents.
ReflectedType	This API supports the product infrastructure and is not intended to be used directly from your code. Gets the class object that was used to obtain this instance through reflection.
