Microsoft.Win32.SafeHandles Namespace

Contains classes that are abstract derivations of safe handle classes that provide common functionality supporting file and operating system handles.

Classes

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	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.

Remarks

These classes are derived from the System.Runtime.InteropServices.SafeHandle and System.Runtime.InteropServices.CriticalHandle classes.
