Question

我正在尝试创建一个SQLite数据库，但在尝试创建它时会不断收到此异常。

我在尝试使用finisar时遇到了同样的异常，但决定尝试使用System.Data.SQLite并且仍然得到相同的异常！

我认为它与我的App.config文件有关，但在这一点上，我完全无能为力。

这是我的代码，以防我编码错误。非常感谢所有帮助！

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

    private void connectToSQLite()
    {
        SQLiteConnection.CreateFile("ExamLog.sqlite");
        SQLiteConnection con = new SQLiteConnection("Date Source=ExamLog.sqlite;Version=3");
        con.Open();

        string sql = "CREATE TABLE EmpInfo (id int, firstName varchar(20), lastName varchar(20)";
        SQLiteCommand cmd = new SQLiteCommand(sql, con);

        cmd.ExecuteNonQuery();


    }

非常感谢！

Also, here's my App.xaml:

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>

    </Application.Resources>
</Application>

感谢您的帮助！

您的拼写错误的“数据源”为“日期来源”。这就是XAML解析器在运行类的构造函数时抛出异常的原因。

create table语句中的另一个错误，缺少右括号。

更正：

SQLiteConnection con = new SQLiteConnection("Data Source=ExamLog.sqlite;Version=3");

string sql = "CREATE TABLE EmpInfo (id int, firstName varchar(20), lastName varchar(20))";

尝试在wpf中创建数据库时，System.Data.SQLite中抛出异常
