我试图在DataGrid中显示SQL Server表的内容。我已经将其减少到最基本的版本，并保留所有默认值，并且看不到任何列标题或任何行。
下面是我的代码：

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        Test1DataSet test1DataSet = new Test1DataSet();
        Test1DataSetTableAdapters.AdminUserTableAdapter tableAdapter =
            new Test1DataSetTableAdapters.AdminUserTableAdapter();
        tableAdapter.Fill(test1DataSet.AdminUser);

       Test1DataSet.AdminUserDataTable dataTable = tableAdapter.GetData();
        Console.WriteLine(dataTable.Count);

        dataGrid.DataContext = dataTable.DefaultView;
    }
}

下面是XAML：

<Grid Name="Grid1">
    <DataGrid Margin="25" Name="dataGrid">
      <!--  <DataGrid.Columns>
            <DataGridTextColumn Header="id" Binding="{Binding id}" />
            <DataGridTextColumn Header="Name" Binding="{Binding LastName}" />
        </DataGrid.Columns> -->
    </DataGrid>
</Grid>

表格定义：CREATE TABLE [dbo].[AdminUser]（[id] INT IDENTITY（1，1）NOT NULL，[EmployeeNumber] NVARCHAR（30）NOT NULL，[FirstName] NVARCHAR（100）NULL，[LastName] NVARCHAR（100）NULL，[isSA] BIT NOT NULL，[isDA] BIT NOT NULL）;
