    I have a list of uploaded files in a textarea datatype. I want to split this list, and take the first item in the array...

    @foreach (string pic in @node.GetPropertyValue("billeder").ToString().Split(',').Take(1)) {
       <p>@pic</p>
    }
    

    Gives me an error... Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Array' does not contain a definition for 'Take'

    What to do?

    Hi Claus

    I think array's don't have the Take method. If you call a ToList() it will probably work

    @foreach (string pic in @node.GetPropertyValue("billeder").ToString().Split(',').ToList().Take(1)) {
       <p>@pic</p>
    }

    Hmmm nope

    Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Array' does not contain a definition for 'ToList'

    I guess you need to add the following using statement to your view

    using System.Linq;
    

    But the ToList() is not needed then I think

    Now i have:

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage<ContentModels.Somethinsomething>
    @using ContentModels = Umbraco.Web.PublishedContentModels;
    @using System.Linq;
    

    in the top of my file - This is not a partial, but a template.

    But i still get the error: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Array' does not contain a definition for 'Take'

    Hi Claus,

    May I ask why you are using the GetPropertyValue syntax ? I see you have models builder enabled.

    What type of property is billeder ? And of course what @node is ?

    Absolutely, and thank you for taking time to help out.

    I am royally confused about Modelsbuilder, so i use what works

    @foreach (string pic in @node.Billeder.ToString().Split(','))
    

    works as well

    "billeder" is a "Textarea" datatype

    enter image description here

    @node is the first child from a node picked with MNTP

    Do you have it working now ? Or not

    Because I tried something similar and didn't even need to include the using statement for system.Linq

    Nope, im still getting: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Array' does not contain a definition for 'Take'

    when doing:

    @foreach (string pic in @node.Billeder.ToString().Split(',').Take(1)) { }
    

    and Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Array' does not contain a definition for 'Tolist'

    when doing

    @foreach (string pic in @node.Billeder.ToString().Split(',').Tolist().Take(1)) { }

    Hi Claus,

    Maybe try to add the following using statement as well

    @using System.Collections.Generic;

    Hmmm,

    Could what is the output when you don't use the take ?

    And what do you get when do : @node.Billeder.ToString().Split(,).GetType().FullName

    Without take:

    enter image description here

    @node.Billeder.ToString().Split(,).GetType().FullName
    

    returns an "argument missing" but

    @node.Billeder.ToString().GetType().FullName
    

    return "System.String"

    And what does this return

    @node.Billeder.ToString().Split(new [] ',').GetType().FullName

    Im a bit confused

    You just want to know the value of @node.Billeder.ToString().Split(new [] ',').GetType().FullName, right. Not used in a ForEach...

    If so, it returns

    Compiler Error Message: CS1514: { expected

    Hi Claus;

    Probably mistyped it. It should be

    @node.Billeder.ToString().Split(new [] { ',' }).GetType().FullName

    So we confirmed that it is indeed an array

    So now we need to figure out why the Take(1) does not work.

    Hi Claus,

    Did some googling and all say is to include a using System.Linq statement

    Coud you try this

    {
    var stringArray = node.Billeder.ToString().Split(',');
    }
    @foreach (string pic in System.Linq.Enumerable.Take(stringArray, 1)) 
    {
    
    }
    

    Calling the Take extension method directly instead of using as an actual extensions method.

    Just to see if it is available.
