enum System.​Security.​Permissions.​SecurityAction

The calling code can access the resource identified by the current permission object, even if callers higher in the stack have not been granted permission to access the resource (see Using the Assert Method).

The ability to access the resource specified by the current permission object is denied to callers, even if they have been granted permission to access it (see Using the Deny Method).

Only the resources specified by this permission object can be accessed, even if the code has been granted permission to access other resources.

The immediate caller is required to have been granted the specified permission. Do not use in the .NET Framework 4. For full trust, use <see cref="T:System.Security.SecurityCriticalAttribute" /> instead; for partial trust, use <see cref="F:System.Security.Permissions.SecurityAction.Demand" /> .
