如何将查询生成的通用列表返回到 DataGrid ItemSource？

Question

我正在从实体模型生成数据网格，这在后面的代码中非常简单。但现在我试图将它绑定在 MVVM 模式中，我似乎无法弄清楚如何返回通用列表。

从模型视图：

    public ??? LoadMoviesMethod()
    {
        ObjectQuery<MovieTable> _movies = dataEntities.MovieTables;

        var query =
            from MovieTable in _movies
            where MovieTable.Rating == "R"
            orderby MovieTable.id
            select new { MovieTable.Title, MovieTable.Rating, MovieTable.Stars, MovieTable.ReleaseYear };

       ??? MoviesList = query.ToList();
       return MoviesList;

//where as the code behind was simply gridName.ItemsSource = query.ToList()

    }

发送到数据网格：

<UserControl x:Class="MovieMockup.MovieMockupListView"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d"
         d:DesignHeight="300" 
         d:DesignWidth="300">
<DataGrid ItemSource="{Binding MovieMockupListModel.MoviesList}">

</DataGrid>
</UserControl>

任何输入将不胜感激！

我通常使用 IList 或 IEnumerable，尽管我想你也可以返回 object
