I've created a helper dll and am trying to get to a certain directory in the media tree.

               DynamicMedia mediaRoot = new DynamicMedia(-1);

               var test = mediaRoot.Descendants().Where(x => x.Name == "Generic Hero Images"); 

Gives an error stating "The type of arguments for method 'umbraco.MacroEngines.DynamicNodeList.Where<T>(string, params object[])' cannot be inferred.

I get the same error if I use

var test = mediaRoot.Descendants().Where("Name == @0", "Generic Hero Images");

If you know how to get these working (or alternatively a better way to approach this) I'd be grateful.

In the past I have used the node id's as Constants but this seems fragile.

Thanks in advance.
