FaceValue; } What happens here is that LINQ calls this expression on every object of the collection and compares the value returned by it (the value of FaceValue in our case) to sort the collection. FaceValue; } This code will produce exactly the same result as the one with the lambda expression. Most of the time, lambda expressions will be the best way to achieve your goals in a short and readable way, and LINQ makes extensive use of it. The Where query operator works the same way, except its parameter is Func
