Random and Max from archetype

Is it possible somehow to randomize the order and take 1 item from an archetype fieldset ?

I have this now

@{
    var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems");

    foreach (var item in testimonials) 
    {
        <h2>@item.GetValue("testimonalItemHeader")</h2>

        @item.GetValue("testimonalItemText")

         <q> @item.GetValue("testimonalItemName")</q>
    }
}

I have tried with

 var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems").RandomOrder().Take(1);

But I am getting an error that Take and RandomOrder is not a part of ArchetypeModel

Have you tried this:

 var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems").OrderBy(x => Guid.NewGuid()).Take(1);

When using the above I am getting

error CS1977: Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type

what about this? (sorry I don't currently have a project with Archetype)
```
 var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems").Fieldsets.OrderBy(x => Guid.NewGuid()).Take(1);
```

OK, one last shot:

var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems").ToList().OrderBy(x => Guid.NewGuid()).Take(1);

Hi Peter,

Can you try this.
```
var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems").ToList().RandomOrder().Take(1);
```
If it's not working, can you post the exact error

Inserting this I am getting the error:
```
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'Archetype.Models.ArchetypeModel' does not contain a definition for 'ToList'
```
the same with Take or RandomOrder

Can you try this :

var testimonials = Umbraco.ContentSingleAtXPath("//HomePage").GetPropertyValue<ArchetypeModel>("testimonialItems").Fieldsets.ToList().RandomOrder().Take(1);

Hi Dave,

Just the same error.

Am I missing something?
