Parameters

rule: FileSystemAccessRule

A FileSystemAccessRule object that represents an access control list (ACL) permission to set for a file or directory.

Exceptions

ArgumentNullException

The rule parameter is null.

Remarks

The SetAccessRule method adds the specified access control list (ACL) rule or overwrites any identical ACL rules that match the FileSystemRights value of the rule parameter. For example, if the rule parameter specifies a Read value and the SetAccessRule method finds an identical ACL rule that specifies the Read value, the identical rule will be overwritten. If the SetAccessRule method finds an identical ACL rule that specifies the Write value, the identical rule will not be overwritten.

Use the following .NET implementation-dependent methods to add or retrieve ACL information from a file:

.NET implementation	Add rules	Retrieve rules
.NET	FileSystemAclExtensions.SetAccessControl(FileInfo, FileSecurity)	FileSystemAclExtensions.GetAccessControl(FileInfo)
.NET Framework	FileInfo.SetAccessControl(FileSecurity)	FileInfo.GetAccessControl()
