Provides a base class for Win32 critical handle implementations in which the value of either 0 or -1 indicates an invalid handle.
Assembly: mscorlib (in mscorlib.dll)
Initializes a new instance of theclass.
Marks the handle for releasing and freeing resources.(Inherited from CriticalHandle.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Frees all resources associated with the handle.(Inherited from CriticalHandle.)
Serves as the default hash function. (Inherited from Object.)
When overridden in a derived class, executes the code required to free the handle.(Inherited from CriticalHandle.)
Sets the handle to the specified pre-existing handle.(Inherited from CriticalHandle.)
Marks a handle as invalid.(Inherited from CriticalHandle.)
Returns a string that represents the current object.(Inherited from Object.)
This class derives from the System.Runtime.InteropServices.CriticalHandle class. It describes the format of an invalid handle. For example, some handles use -1 as an invalid handle value, while others use 0. Further derivations of this class (for example, file or registry handles) can specialize this further.
Use theclass when you need to wrap an unmanaged resource that does not have an existing managed wrapper.
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 try/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.
See the CriticalHandle class for important information on critical handle security and thread safety.
