Remarks
Caution
Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.
This enumeration is used by EnvironmentPermission.
Note
Although NoAccess and AllAccess appear in EnvironmentPermissionAccess, they are not valid for use as the parameter for EnvironmentPermission.GetPathList because they describe no environment variable access types or all environment variable access types, respectively, and GetPathList expects a single environment variable access type.
