无效的绑定路径＆＃39; MyStatic＆＃39; ：物业＆＃39; MyStatic＆＃39;无法找到类型＆＃39; CreatePage＆＃39;

Question

所以我一直在为我的问题寻找解决方案。我似乎无法绑定到我的models文件夹中的observableCollection。我可以在其中添加项目，并在以后的体育场中使用一些C＃代码检索这些项目。但我似乎无法绑定到名为CreatePage的页面中的项目。

我不断收到此消息：无效的绑定路径＆＃39;问题列表＆＃39; ：财产问题清单＆＃39;无法找到类型＆＃39; CreatePage＆＃39;。

带有observableCollection的类：

public partial class MyStatic
{
        static MyStatic()
        {
            Questionlist = new ObservableCollection<QuestionList>();            
        }
        public static ObservableCollection<QuestionList> Questionlist;
    }
public class QuestionList
{
    public string Question { get; set; }
    public string Answer { get; set; }
    public string Delete { get; set; }
    public string Correct { get; set; }
    public string Wrong { get; set; }
    public string UserAnswer { get; set; }
}

这是我的Xaml：

<ScrollViewer Grid.Row="4"
                  Grid.ColumnSpan="2"
                  Margin="20,10"
                  MaxWidth="650">
        <RelativePanel>
            <ListView Name="Questionviewlist"
                      ItemsSource="{x:Bind Questionlist}">
                <ListView.ItemTemplate>
                    <DataTemplate x:DataType="data:QuestionList">
                        <TextBlock Name="Questionview"
                                   Text="{x:Bind Question}"
