C# Extension method for checking attributes

Question

Sorry if this is a stupid noob question please be gentle with me I\'m trying to learn...

I want to test against the attribute methods of things like models and controlle

Answer 1

You can check whether a method has a particular attribute by doing this:

typeof(Controller).GetMethod("MethodName").GetAttributes().Any();

In terms of the extension method itself, provided that you're looking for an extension method on the Controller type, how about something like this:

public static bool HasAttribute(this Controller controller, string methodName)
{
   return controller.GetType().GetMethod(methodName).GetCustomAttributes(typeof(A), true).Any();
}

Remember, extension methods are invoked on an instance, so to use this you still need an instance of Controller:

var controller = new Controller();
Assert.IsTrue(controller.HasAttribute("Method1"));
