You cannot remove permissions from an unrestricted permission set. The permission set remains unrestricted after you attempt to remove the permission, and an exception is not thrown. |
The following C# code attempts to remove the FileIOPermission from the FullTrust permission set, but the permission is not removed.
PolicyLevel myPol = PolicyLevel.CreateAppDomainLevel();
PermissionSet myPermSet = myPol.GetNamedPermissionSet("FullTrust");
myPermSet.RemovePermission(typeof(FileIOPermission));
Notes to Inheritors:
When you inherit from PermissionSet, you can change the behavior of the RemovePermission method by overriding the RemovePermissionImpl method.
The following code example shows the use of the RemovePermission method to remove a FileIOPermission from a permission set. This code example is part of a larger example provided for the PermissionSet class.
