Question

我正在尝试创建一个SQL查询并将结果保存在XML文件中，但是我得到的错误就像我附在这里的图片一样无效栏！此查询在SQL服务器中正常工作但不在此处

namespace xxxxxxxxxxxx
{
    public partial class MainWindow : Window
    {
        string vinValue;
        string operationValue;
        string serviceValue;

    public MainWindow()
    {
        InitializeComponent();
    }

    private void FrameLoad_Activated(object sender, EventArgs e)
    {

    }

    private void btnGo_Click(object sender, RoutedEventArgs e)
    {

        DataSet ds = new DataSet();
        SqlDataAdapter adapter;

        string sql = String.Format("SELECT FGACJD_Vin_Ecu.Vin,FGACJD_Vin_Ecu.NHard,"+
            "FGACJD_Vin_Ecu.NVerHard,FGACJD_Vin_Ecu.NSoft,FGACJD_Vin_Ecu.NVerSoft,"+

        //TextOutput.Text = sql;
        string connectionString = "user id=xxx;password=xxx;"+

        SqlConnection conn = new SqlConnection(connectionString);
        try
        {
            conn.Open();
        }
        catch (Exception)
        {
            string err = "Database error contact administrator";
            MessageBox.Show(err, "Error!");
        }

        try
        {

            adapter = new SqlDataAdapter(sql, conn);
            adapter.Fill(ds);

            MessageBox.Show(ex.ToString());
        }
   }

    private void TextInput_TextChanged(object sender, TextChangedEventArgs e)
    {
        vinValue = TextInput.Text;
    }

    private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        var comboBox = sender as ComboBox;
        serviceValue = comboBox.SelectedItem as string;

    }

    private void Operation_Loaded(object sender, RoutedEventArgs e)
    {
        List<string> data = new List<string>();
        data.Add("MOC");
        var comboBox = sender as ComboBox;
        comboBox.ItemsSource = data;
        comboBox.SelectedIndex = 0;
    }

    private void Operation_SelectionChanged(object sender, SelectionChangedEventArgs e)

        var comboBox = sender as ComboBox;
        operationValue = comboBox.SelectedItem as string;

}

我收到此错误
