Exception: 'Object' does not contain a definition for 'Take'

Razor

foreach (var mc in CurrentNode.hAuditSpotlight.Skip(SkipContents).Take(10))
{
}

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'object' does not contain a definition for 'Take'
   at CallSite.Target(Closure , CallSite , Object , Int32 )
   at System.Dynamic.UpdateDelegates.UpdateAndExecute2[T0,T1,TRet](CallSite site, T0 arg0, T1 arg1)
   at KPMGAudit.Web.MainContents.FetchMainContentsByCategory(String Category, Int32 StartsFrom) in XXX:line XXX

If I use "Skip()" alone, it works; also "Take()" alone works, but while using both simultaneously throws the above exception.

Any solution???!!!

Hi, could you post a little more of your code, specifically what is CurrentNode and also what is hAuditSpotlight?

Thanks,

Jeavon

Just an idea: I think it would be better if you use Where instead of Skip...
```
.Where("something something").Take(10)
```

Hi Jeavon,

Thanks for your reply. I've posted a little more of my code here.

CurrentNode = new DynamicNode().NodeById(1050);
//CurrentNode.hAuditSpotlight is a Multi-Node Tree picker property.

foreach(var mc in CurrentNode.hAuditSpotlight.Skip(SkipContents).Take(10))
{
}

Ok, you need to a fair bit more to get MNTP converted to objects so you can skip and take:

@{
    var currentNode = Library.NodeById(1050);

    if (currentNode.HasValue("hAuditSpotlight"))
    {
        IEnumerable<DynamicNode> publishedNodeList = Library.NodesById(Model.hAuditSpotlight.Split(','));
        publishedNodeList = publishedNodeList.Where(x => x.GetType() != typeof(DynamicNull) && x.Id > 0);
        dynamic hAuditSpotlight = new DynamicNodeList(publishedNodeList);

        if (hAuditSpotlight.Any())
        {
            foreach (var item in hAuditSpotlight.Skip(1).Take(10))
            {                   
                <p>@item.Name</p>      
            }               
        }
    }            
}
