Using Skip() on a string array
I am pulling af comma-separated list from a multiple media picker.
This get's me: "1111,4444,8888".

I want to foreach the list (and skip the first image), so I can get the media URL's - I am doing that by splitting:
```
@foreach(var test in CurrentPage.images.Split(',').Skip(1)){
  @test.Url
}
```
I then get an Exception error:
```
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Array' does not contain a definition for 'Skip'
```
How can I use Skip(), Take() and so on, when I foreach a splitted comma-separated list?

Hi Ørskov Gruppen A/S,

Try to see the documentation about using the multiple media picker https://our.umbraco.org/documentation/using-umbraco/backoffice-overview/property-editors/Built-in-Property-Editors-v7/Media-Picker. I think I would do it like this. So I add the skip to the foreach loop.

@if (CurrentPage.HasValue("caseStudyImages"))
{
    var caseStudyImagesList = CurrentPage.CaseStudyImages.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
    var caseStudyImagesCollection = Umbraco.Media(caseStudyImagesList);

    foreach (var caseStudyImage in caseStudyImagesCollection.Skip(1))
    {
        <img src="@caseStudyImage.Url" style="width:300px;height:300px" />
    }
}

Hope this helps,

/Dennis
