Remarks
PermitOnly is similar to Deny, in that both cause stack walks to fail when they would otherwise succeed. The difference is that Deny specifies permissions that will cause the stack walk to fail, but PermitOnly specifies the only permissions that do not cause the stack walk to fail. Call this method to ensure that your code can be used to access only the specified resources.
PermitOnly is ignored for a permission not granted because a demand for that permission cannot succeed. However, if code lower on the call stack later calls Demand for that permission, a SecurityException is thrown when the stack walk reaches the code that tried to call PermitOnly. This is because the code that called PermitOnly has not been granted the permission, even though it called PermitOnly for that permission. The call stack is typically represented as growing down, so that methods higher in the call stack call methods lower in the call stack.
