Cast variable as an ItemSource for a LongListViewer

Question

I have a variable named

items

that finds a set of descendants of an XML element and binds them to a

TextBlock

on a

LongListViewer

in Windows Phone 8.1 Silverlight. When I go and try to set the

ItemSource

with this variable, it comes up with an error:

Cannot implicitly convert type

System.Collections.Generic.IEnumerable<Lists.ListsXmlBinder>
to

System.Collections.IList
. An explicit conversion exists (are you
missing a cast?)

Here is my code:

using (var storage = IsolatedStorageFile.GetUserStoreForApplication())

{

    using (Stream stream = storage.CreateFile("list.xml"))

    {

        XDocument document = XDocument.Load(stream);

        document.Element("lists").Add(new XElement("list", new XElement("name", "random list"), new XElement("date", DateTime.Now.ToString())));

        document.Save(stream);



        var items = from query in document.Descendants("list")

                    select new ListsXmlBinder

                    {

                        Name = query.Element("name").Value,

                        Date = query.Element("date").Value

                    };



        lists_ListViewer.ItemsSource =  items;

    }

}

Any suggestions on how to solve the problem?

Answer 1

Just add a call to ToList() to convert the IEnumerable to a list:

var items = (from query in document.Descendants("list")
                            select new ListsXmlBinder
                            {
                                Name = query.Element("name").Value,
                                Date = query.Element("date").Value
                            }).ToList();
