我在填写DataGrid数据时遇到问题.这是我的代码,用于反序列化XML file并将信息放入数组中,然后将其Array放入DataGrid使用ItemsSource方法中.

public partial class Teacher_Page : Window
{
    List<User> pupils;

    public Teacher_Page()
    {
        InitializeComponent();
        XmlSerializer deserializer = new XmlSerializer(typeof(List<User>));
        TextReader textReader = new StreamReader("../../../Pupils.xml");
        pupils = (List<User>)deserializer.Deserialize(textReader);
        textReader.Close();

        lbtest.Content = pupils[2].Name;
        dataResults.ItemsSource = pupils;

    }
}

但是,当我运行程序时,我DataGrid会填充正确的行数,arraylist但是行是空的并且没有列.lbltest从中输出一个字符串arraylist来证明它arraylist不是空的,这是正确的. AutoGenerateColumns也设置为true.

XAML

<DataGrid x:Name="dataResults" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="248" Width="610" IsReadOnly="True"/>

public class User
{
    public String Name;
    public int …
