Microsoft.Win32.SafeHandles Namespace
The Microsoft.Win32.SafeHandles namespace contains classes that are abstract derivations of safe handle classes that provide common functionality supporting file and operating system handles.
| Class | Description | |
|---|---|---|
 | CriticalHandleMinusOneIsInvalid | Provides a base class for Win32 critical handle implementations in which the value of -1 indicates an invalid handle. |
| CriticalHandleZeroOrMinusOneIsInvalid | Provides a base class for Win32 critical handle implementations in which the value of either 0 or -1 indicates an invalid handle. |
| SafeAccessTokenHandle | Provides a safe handle to a Windows thread or process access token. For more information see Access Tokens |
| SafeFileHandle | Represents a wrapper class for a file handle. |
| SafeHandleMinusOneIsInvalid | Provides a base class for Win32 safe handle implementations in which the value of -1 indicates an invalid handle. |
| SafeHandleZeroOrMinusOneIsInvalid | Provides a base class for Win32 safe handle implementations in which the value of either 0 or -1 indicates an invalid handle. |
| SafeMemoryMappedFileHandle | Provides a safe handle that represents a memory-mapped file for sequential access. |
| SafeMemoryMappedViewHandle | Provides a safe handle that represents a view of a block of unmanaged memory for random access. |
| SafeNCryptHandle | This API supports the product infrastructure and is not intended to be used directly from your code. Provides a safe handle that can be used by Cryptography Next Generation (CNG) objects. |
| SafeNCryptKeyHandle | Provides a safe handle that represents a key (NCRYPT_KEY_HANDLE). |
| SafeNCryptProviderHandle | Provides a safe handle that represents a key storage provider (NCRYPT_PROV_HANDLE). |
| SafeNCryptSecretHandle | Provides a safe handle that represents a secret agreement value (NCRYPT_SECRET_HANDLE). |
| SafePipeHandle | Represents a wrapper class for a pipe handle. |
| SafeProcessHandle | Provides a managed wrapper for a process handle. |
| SafeRegistryHandle | Represents a safe handle to the Windows registry. |
| SafeWaitHandle | Represents a wrapper class for a wait handle. |
| SafeX509ChainHandle | Provides a wrapper class that represents the handle of an X.509 chain object. For more information, see X509Chain. |
These classes are derived from the System.Runtime.InteropServices::SafeHandle and System.Runtime.InteropServices::CriticalHandle classes.
