Remarks

This class should be used when working with native code that expects an NCRYPT_KEY_HANDLE.

Important

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.

Constructors

SafeNCryptKeyHandle()	Initializes a new instance of the SafeNCryptKeyHandle class.
SafeNCryptKeyHandle(IntPtr, SafeHandle)	Instantiates a new instance of the SafeNCryptKeyHandle class.

Fields

handle

Specifies the handle to be wrapped.

(Inherited from SafeHandle)

Properties

IsClosed	Gets a value indicating whether the handle is closed. (Inherited from SafeHandle)
IsInvalid	Gets a value that indicates whether the handle is invalid. (Inherited from SafeNCryptHandle)

Methods

Close()	Marks the handle for releasing and freeing resources. (Inherited from SafeHandle)
DangerousAddRef(Boolean)	Manually increments the reference counter on SafeHandle instances. (Inherited from SafeHandle)
DangerousGetHandle()	Returns the value of the handle field. (Inherited from SafeHandle)
DangerousRelease()	Manually decrements the reference counter on a SafeHandle instance. (Inherited from SafeHandle)
Dispose()	Releases all resources used by the SafeHandle class. (Inherited from SafeHandle)
Dispose(Boolean)	Releases the unmanaged resources used by the SafeHandle class specifying whether to perform a normal dispose operation. (Inherited from SafeHandle)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (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)
ReleaseHandle()	This API supports the product infrastructure and is not intended to be used directly from your code. Releases a handle used by a Cryptography Next Generation (CNG) object. (Inherited from SafeNCryptHandle)
ReleaseNativeHandle()	This API supports the product infrastructure and is not intended to be used directly from your code. Releases a native handle used by a Cryptography Next Generation (CNG) object. (Inherited from SafeNCryptHandle)
SetHandle(IntPtr)	Sets the handle to the specified pre-existing handle. (Inherited from SafeHandle)
SetHandleAsInvalid()	Marks a handle as no longer used. (Inherited from SafeHandle)
ToString()	Returns a string that represents the current object. (Inherited from Object)
