Fields

AllAccess 3

Read and Write access to environment variables. AllAccess represents multiple EnvironmentPermissionAccess values and causes an ArgumentException when used as the flag parameter for the GetPathList(EnvironmentPermissionAccess) method, which expects a single value.

NoAccess 0

No access to environment variables. NoAccess represents no valid EnvironmentPermissionAccess values and causes an ArgumentException when used as the parameter for GetPathList(EnvironmentPermissionAccess), which expects a single value.

Read 1

Only read access to environment variables is specified. Changing, deleting and creating environment variables is not included in this access level.

Write 2

Only write access to environment variables is specified. Write access includes creating and deleting environment variables as well as changing existing values. Reading environment variables is not included in this access level.

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 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.
