The MemoryMappedFileSecurity class specifies the access rights for a memory-mapped file and how access attempts are audited. This class represents access and audit rights as a set of rules.

The MemoryMappedFileSecurity class is an abstraction of the underlying Microsoft Windows file security system. In this system. It hides many of the details of DACLs and SACLs.

Use the MemoryMappedFileSecurity class to retrieve, add, or change the access rules that represent the DACL and SACL of a pipe.

To apply new or changed access or audit rules to a memory-mapped file, use the SetAccessControl method. To retrieve access or audit rules from an existing file, use the GetAccessControl method.

The following MemoryMappedFile methods take a MemoryMappedFileSecurity object as a parameter:

.NET Framework

Supported in: 4

.NET Framework Client Profile

Supported in: 4

Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
