Handle Minus One IsInvalid Class
Provides a base class for Win32 safe handle implementations in which the value of -1 indicates an invalid handle.

[System.Security.SecurityCritical] public abstract class SafeHandleMinusOneIsInvalid : System.Runtime.InteropServices.SafeHandle
type SafeHandleMinusOneIsInvalid = class inherit SafeHandle
Public MustInherit Class SafeHandleMinusOneIsInvalid Inherits SafeHandle
This class derives from the System.Runtime.InteropServices.SafeHandle class. It describes the format of an invalid handle that uses a value of -1. Further derivations of this class (for example, file or registry handles) can specialize this further. See the SafeFileHandle class for an example of a class that derives from SafeHandleMinusOneIsInvalid.
This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a
catch block. To dispose of it indirectly, use a language construct such as
using (in C#) or
Using (in Visual Basic). For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.
