So, it's been a while, but I thought I take moment and do my annual blog post ;).
I've been playing around with ASP.NET MVC and the Linq stuff for NHibernate recently. I was in need of an OrderBy extension method that could take a SQL-Like OrderBy string and sort a IQueryable<> or IEnumerable<> collection. I wrote up an implementation that worked, but I just wasn't satisfied with its internals (quite a bit of reflection to get the correct type to construct a LambdaExpression, etc)
At any rate, I couldn't leave well enough alone, and, after a bit of Googling, I ran across this StackOverflow answer about Dynamic LINQ OrderBy. The extension method wasn't exactly what I was looking for, but that ApplyOrder method is slick, and solved the portion of my implementation that was bothering me.
So, I though I would post up my version in case anybody finds it useful. It handles the following inputs:
list.OrderBy("SomeProperty"); list.OrderBy("SomeProperty DESC"); list.OrderBy("SomeProperty DESC, SomeOtherProperty"); list.OrderBy("SomeSubObject.SomeProperty ASC, SomeOtherProperty DESC");Dynamic SQL-like Linq OrderBy Extension Anyway, hope someone finds it useful. And if you see any areas that could use some TLC please let me know A
