    Get All Images from Media Folder Problem

    In Umbraco 7 I create an image gallery (bootstrap carousel) from all images in a selected folder (mappe). Below is my code for V7, but it doesn't work i V 8:

    @using System.Globalization
    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage
    
                        <!-- Wrapper for slides -->
                        <div class="carousel-inner">
                            @{
                                bool first = true;  
                                var myMediaFolder = Umbraco.Media(@CurrentPage.Mappe);
                                foreach (var mediaItem in myMediaFolder.Children)      
                                {
                                    string aktiv = (first ? "active" : "");
                                    <div class="carousel-item @aktiv">
                                        <img src="@mediaItem.Url" alt="@mediaItem.Name" style="width: 100%">
                                    </div>
                                    first = false;
                                }  
                            }
                        </div>

    Hi Ole

    UmbracoTemplatePage and CurrentPage have been removed from Umbraco 8.

    In stead you should use UmbracoViewPage and strongly typed access to your properties. If you use modelsbuilder, that would be Model.Mappe.

    @inherits UmbracoViewPage
    
                        <!-- Wrapper for slides -->
                        <div class="carousel-inner">
                            @{
                                bool first = true;  
                                var myMediaFolder = Model.Mappe; // or Model.GetValue<IPublishedContent>("mappe")
                                foreach (var mediaItem in myMediaFolder.Children)      
                                {
                                    string aktiv = (first ? "active" : "");
                                    <div class="carousel-item @aktiv">
                                        <img src="@mediaItem.Url" alt="@mediaItem.Name" style="width: 100%">
                                    </div>
                                    first = false;
                                }  
                            }
                        </div>

    OK, now I have the folder (I can get it's name), but getting the children fails. How do I cast it as a media-folder

    Compiler Error Message: CS0446: Foreach cannot operate on a 'method group'. Did you intend to invoke the 'method group'?

    Try this

    foreach (var mediaItem in myMediaFolder.Children())

    If Model.GalleriMappe is of IEnumerable<IPublishedContent> you should probably not call children since that model already contains a collection. Try:

    foreach (var mediaItem in myMediaFolder)

    That doesn't throw any errors, but gives me one elemen with the name of the chosen folder = Forside:

     <div class="carousel-item active">
                                        <img src="" alt="Forside" style="width: 100%">
                                    </div>

    foreach (var mediaItem in myMediaFolder.SelectMany(x => x.Children()))

    Thanks a lot guys. That was the trick. Have a very nice evening :)

    <div class="carousel-inner">
                            @{
                                bool first = true;  
                                var myMediaFolder = Model.GalleriMappe;
                                foreach (var mediaItem in myMediaFolder.SelectMany(x => x.Children()))      
                                {
                                    string aktiv = (first ? "active" : "");
                                    <div class="carousel-item @aktiv">
                                        <img src="@mediaItem.Url" alt="@mediaItem.Name" style="width: 100%">
                                    </div>
                                    first = false;
    
                                }  
                            }
                        </div>
