我在商店里发布了.Net毛伊岛应用程序。在Android是所有的罚款，但我有一个严重的错误，在应用程序商店.我在iOS的调试模式下测试了我的应用程序，它很好，没有问题。但是当我在商店里发布应用程序时，它崩溃了。
在我的应用程序中有很多具有类似功能的页面，所以我不明白这个问题。在这个页面中，我有一个列表视图，如代码所示：

List<ModelClass> GeneralDBClassResult = new List<ModelClass>();
string companyCode = "";

        public Page(List<ModelClass> fgdbc, string cCode)
        {
            InitializeComponent();

            LoadComponents(fgdbc, cCode);
        }

        private async void LoadComponents(List<ModelClass> fgdbc, string cCode)
        {
            try
            {
                companyCode = cCode;
                ThisPage.Title = cCode;

                if (fgdbc != null)
                {
                    GeneralDBClassResult = fgdbc;
                    listView.ItemsSource = fgdbc.Where(c => c.Id >= 0).Where(c => c.Contact_Code == cCode).OrderByDescending(c => c.Samples_Date).GroupBy(c => c.Samples_Date.Year);
                }
            }
            catch (Exception ex)
            {
                connetionDBClass.PublicErrorInDB(ex.ToString());
            }
        }

这是我在XAML中的列表视图：

<ListView Grid.Row="1" x:Name="listView" IsGroupingEnabled="True" ItemSelected="listView_ItemSelected" IsPullToRefreshEnabled="False" GroupDisplayBinding="{Binding Key}" GroupShortNameBinding="{Binding Key}">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell>
                            <ViewCell.View>
                                <Grid RowDefinitions="*,*,*,*" ColumnDefinitions="auto,*,*" Padding="5">

                                    ...

                                </Grid>
                            </ViewCell.View>
                        </ViewCell>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>

我得到的，是一个错误，当我试图添加项目的列表视图在这一行
listView.ItemsSource = fgdbc.Where(c => c.Id >= 0).Where(c => c.Contact_Code == cCode).OrderByDescending(c => c.Samples_Date).GroupBy(c => c.Samples_Date.Year);
这是我得到的错误：
