The System.IO.MemoryMappedFiles.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 System.IO.MemoryMappedFiles.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 System.IO.MemoryMappedFiles.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 MemoryMappedFile.SetAccessControl(MemoryMappedFileSecurity) method. To retrieve access or audit rules from an existing file, use the MemoryMappedFile.GetAccessControl method.

The following System.IO.MemoryMappedFiles.MemoryMappedFile methods take a System.IO.MemoryMappedFiles.MemoryMappedFileSecurity object as a parameter:

• MemoryMappedFile.CreateNew(string, long, MemoryMappedFileAccess, MemoryMappedFileOptions, MemoryMappedFileSecurity, System.IO.HandleInheritability)

• MemoryMappedFile.CreateFromFile(System.IO.FileStream, string, long, MemoryMappedFileAccess, MemoryMappedFileSecurity, System.IO.HandleInheritability, bool)

• MemoryMappedFile.SetAccessControl(MemoryMappedFileSecurity)

• MemoryMappedFile.CreateOrOpen(string, long, MemoryMappedFileAccess, MemoryMappedFileOptions, MemoryMappedFileSecurity, System.IO.HandleInheritability)
