DataTable和DataGrid集成

Question

我想将DataTable用于WPF DataGrid。我实际上是在几个月前制作的示例程序中使用它，但我找不到源代码。所以，我试过了。

XAML：

<DataGrid x:Name="dataGrid" HorizontalAlignment="Left" Margin="10,256,0,0" VerticalAlignment="Top" Height="291" Width="800">
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding Path=Name}" Width="180" Header="Name" CanUserResize="False"
                                IsReadOnly="True" />
        <DataGridTextColumn Binding="{Binding Path=Position}" Width="180" Header="Position" CanUserResize="False"
                                IsReadOnly="True" />
        <DataGridTextColumn Binding="{Binding Path=E-Mail}" Width="280"  Header="E-Mail" CanUserResize="False"
                                IsReadOnly="True" />
    </DataGrid.Columns>

</DataGrid>

C＃：

var contacts = new DataTable();

contacts.Columns.Add("Name");
contacts.Columns.Add("Position");
contacts.Columns.Add("E-Mail");

foreach (var x in y)
{
    contacts.Rows.Add(x.foo, x.bar, x.foobar);
}

dataGrid.ItemsSource = contacts.DefaultView;

但是，列似乎要添加两次：

将Datagrid的 AutoGenerateColumns 属性设置为 false

[('Let', 'O'), ("'s", 'O'), ('meet', 'O'), ('on', 'O'), ('wednesday', 'DATE'), ('at', 'O'), ('09:00am', 'O'), ('.', 'O')]
