c# - IEnumerable OrderBy -

I'm using IEnumerable orderbars to sort my items in ascending format, but this is my query in this way Does not work:

  IEnumerable & lt; Step & gt; Steps = allsteps Where (step = & gt; step.x  

It is not necessary to use orderborder or order-bide order

Why?

I want to use the Sum () method is necessary for ordering certain items and items (there are some rules)

I read in MSDN That should be enumerated to work, but what's the best way (I did not try to do this)

Edit: x and y are type of double . I checked in the quick check of the first thing (steps first ()) of my steps.

First of all, why not put it in one line only.

var steps = allsteps Where (step = & gt; step.x X is not primitive or IComparable or ICOPERABLE & Lieutenant; Type FX & gt; Then you will not be able to order your list with or without LINQ.
