The SafeNCryptHandle type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | SafeNCryptHandle | Infrastructure. Initializes a new instance of the SafeNCryptHandle class. |
| Name | Description | |
|---|---|---|
![]() | 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 SafeHandleZeroOrMinusOneIsInvalid.) |
| Name | Description | |
|---|---|---|
![]() | Close | Marks the handle for releasing and freeing resources. (Inherited from SafeHandle.) |
![]() | DangerousAddRef | 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.) |
![]() | Finalize | Frees all resources associated with the handle. (Inherited from SafeHandle.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (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 | Infrastructure. Releases a handle used by a Cryptography Next Generation (CNG) object. (Overrides SafeHandle::ReleaseHandle().) |
![]() | ReleaseNativeHandle | Infrastructure. Releases a native handle used by a Cryptography Next Generation (CNG) object. |
![]() | SetHandle | 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.) |
