Which code segment should you use as the body for the CreateController method in AdminVerifierFactory.cs?

A . Option A
B . Option B
C . Option C
D . Option D

View Answer

Answer: D

Explanation:

The MemberInfo.CustomAttributes property gets a collection that contains this member’s custom attributes.

The Any() statement will either return null or a collection of matched custom attributes. If it matches one or more, the controller is secure, otherwise an exception is thrown.

From scenario: The application contains a header that is visible on every page. If the logged-on user is an administrator, then the header will contain links to administrative functions. This information is read from a cookie that is set on the server. The administrative links must not be present if an error condition is present.

Incorrect:

Not B: controller.GetType().Attributes will not return custom attributes.
