数据网格中的 C# UWP - CSV

Question

I have been attempting to migrate my program from winForms to UWP as a learning exercise; I am new to C#.

In my winForms code I used:

private void BindData(string filePath)
        {
            DataTable dt = new DataTable();
            string[] lines = File.ReadAllLines(filePath);
            if (lines.Length > 0)
            {
                //first line to create header
                globals.count = lines.Length;
                string firstLine = lines[0];
                string[] headerLabels = firstLine.Split(',');
                foreach (string headerWord in headerLabels)
                {
                    dt.Columns.Add(new DataColumn(headerWord));
                }
                //For Data
                for (int i = 1; i < 100; i++)
                {
                    string[] dataWords = lines[i].Split(',');
                    DataRow dr = dt.NewRow();
                    int columnIndex = 0;
                    foreach (string headerWord in headerLabels)
                    {
                        dr[headerWord] = dataWords[columnIndex++];
                    }
                    dt.Rows.Add(dr);
                }
          }
    }

How can I replicate this. I have attempted following this guide and this guide

UWP - CSV in Datagrid

For loading csv data and display into DataGrid control, you could refer my previous case reply that load the csv file and parse into DataGrid ItemResource . That reply contain the complete xaml and code behind. Please note the csv file stored in the project folder. if the file stored in other location within your scenario, we suggest use FileOpenPicker to access the csv file.

Xaml Code

    <controls:DataGrid
        x:Name="MyDataGrid"
        HorizontalAlignment="Stretch"
        VerticalAlignment="Stretch"
        AlternatingRowBackground="Transparent"
        AlternatingRowForeground="Gray"
        AreRowDetailsFrozen="False"
        AreRowGroupHeadersFrozen="True"
        AutoGenerateColumns="False"
        CanUserReorderColumns="True"
        CanUserResizeColumns="True"
        CanUserSortColumns="False"
        ColumnHeaderHeight="32"
        FrozenColumnCount="0"
        GridLinesVisibility="None"
        HeadersVisibility="Column"
        HorizontalScrollBarVisibility="Visible"
        IsReadOnly="False"
        Loaded="DataGrid_Loaded"
        MaxColumnWidth="400"
        RowDetailsVisibilityMode="Collapsed"
        RowGroupHeaderPropertyNameAlternative="Range"
        SelectionMode="Extended"
        VerticalScrollBarVisibility="Visible"
        >
        <controls:DataGrid.RowGroupHeaderStyles>
            <Style TargetType="controls:DataGridRowGroupHeader">
                <Setter Property="Background" Value="LightGray" />
            </Style>
        </controls:DataGrid.RowGroupHeaderStyles>
    
        <controls:DataGrid.Columns>
            <controls:DataGridTextColumn
                Binding="{Binding Id}"
                Header="Id"
                Tag="Id"
                />
            <controls:DataGridTextColumn
                Binding="{Binding Title}"
                Header="Title"
                Tag="Title"
                />
            <controls:DataGridComboBoxColumn
                Binding="{Binding Link}"
                Header="Link"
                Tag="Link"
                />
            <controls:DataGridTextColumn
                Binding="{Binding Type}"
                Header="Type"
                Tag="Type"
                />
            <controls:DataGridTextColumn
                Binding="{Binding Remark}"
                Header="Remark"
                Tag="Remark"
                />
            <controls:DataGridTextColumn
                Binding="{Binding Time}"
                Header="Time"
                Tag="Time"
                />
        </controls:DataGrid.Columns>
    </controls:DataGrid>

Model class

    public class Item
    {
        public string Id { get; set; }
        public string Title { get; set; }
        public string Link { get; set; }
        public string Type { get; set; }
        public string Remark { get; set; }
        public string Time { get; set; }
    }

**Data Process**

    private ObservableCollection<Item> Items;
    private void DataGrid_Loaded(object sender, RoutedEventArgs e)
    {
        using (var reader = new StreamReader("Assets\\Archive.csv",true))
        using (var csv = new CsvReader(reader))
        {
            var records = csv.GetRecords<Item>();
            Items = new ObservableCollection<Item>(records);           
        }
    
        MyDataGrid.ItemsSource = Items;           
    }
