The method used to access the properties of a specific instance of an attribute is GetCustomAttribute. This method is part of the reflection functionality in .NET, which allows developers to obtain information about attributes applied to members of classes or other types. When you have an instance of a class with attributes, you can use GetCustomAttribute to retrieve a specific attribute of that class and then access its properties. This is essential for scenarios where you are dynamically inspecting types, such as frameworks or libraries that depend on metadata.

For context, the other options serve different purposes. GetProperties typically refers to obtaining the properties of a class or an object, not specifically related to attributes. MoveNext is a method used in enumerators to advance to the next element in a collection, which is not relevant to attributes. CheckAttribute does not correspond to any standard method in .NET for accessing attribute properties. Hence, the correct choice effectively aligns with the mechanics of how attributes are utilized and accessed within .NET applications.
