NFluent: fluently check a property of an exception

Question

I have a function that is supposed to raise an exception FooException. This exception has a list of items stored in one of its properties AffectedElements. How can I perform tests against this list? For example:

Check.ThatCode(() => somefunction("qux", 1, null))
     .Throws<FooException>()
     .«WhatDoIPutHere»
     .IsInAscendingOrder();

Answer 1

As of now, there is no way to extract a field/property from an exception to check it. The best you can do is use WithProperty which only support equality check:

Check.ThatCode(() => somefunction("qux", 1, null))
 .Throws<FooException>()
 .WithProperty("propName", expectedValue);

Update: The latest version of NFluent offers a feature for that. see the wiki
