Get order from API by order #

Hi, I'm using C# and the ShopifySharp API wrapper for a project and I need to be able to retreive an order with no other input by from the user besides the order number. Is this possible with the Shopify API? I found some old forum threads here from ~2013 saying to filter by the "name" property but looking through the documentation now I can't find any mention of that, and it doesnt exist as a property for the OrderFilter object in the API wrapper. I don't mind using a different REST client but as I mentioned there's absolutely 0 documentation of the type of functionality tha I was reading about in these old forum posts so I don't want to put in the effort to switch over if it might not work.
