The code that checks for an attribute is relatively simple Given a PropertyInfo object (obtained via reflection), you call GetCustomAttributes() and specify the attribute sought, followed by whether to check any overloaded methods (Alternatively, you can call the GetCustomAttributes() method without the attribute type to return all of the attributes) Although it is possible to place code for finding the CommandLineSwitchRequiredAttribute attribute within the CommandLineHandler 's code directly, it makes for better object encapsulation to place the code within the CommandLineSwitchRequiredAttribute class itself This is frequently the pattern for custom attributes What better location to place code for finding an attribute than in a static method on the attribute class

You use the same syntax on a generic class when the method requires an additional type parameter not included in the class type parameter list In this example, the method is static but C# does not require this Note that generic methods, like classes, can include more than one type parameter The arity (the number of type parameters) is an additional distinguishing characteristic of a method signature

Type Inferencing The code used to call the Min<T> and Max<T> methods looks like that shown in Listing 1136
