enum EnvironmentPermissionAccess

Remarks

This enumeration is used by EnvironmentPermission.

Note   Although NoAccess and AllAccess appear in EnvironmentPermissionAccess, they are not valid for use as the parameter for 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.

Members
