AutomationNull AutomationNull AutomationNull AutomationNull Class


This is a singleton object that is used to indicate a void return result.

public ref class AutomationNull abstract sealed
public static class AutomationNull
type AutomationNull = class
Public Class AutomationNull


It's a singleton class. Sealed to prevent subclassing. Any operation that

returns no actual value should return this object AutomationNull.Value.

Anything that evaluates an MSH expression should be prepared to deal

with receiving this result and discarding it. When received in an

evaluation where a value is required, it should be replaced with null.
