所以我有这个我正在为我的大学工作的课程。该程序从网页（在本例中为Reddit）中获取数据，并将其添加到SQlite服务器中。除了将数据插入表格的部分外，一切似乎都在顺利运行。这是代码：
class Program
{
static string connString = @"Data Source=C:\SQLite\mydatabase;Version=3;";
static SQLiteConnection conn = new SQLiteConnection(connString);
public SQLiteDataAdapter da = new SQLiteDataAdapter();
DataTable dt = new DataTable();
static void Main(string[] args)
{
FirefoxDriver driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://www.reddit.com/");;
Console.WriteLine("collecting data");

它说可能存在语法错误或缺少数据库，但我确信数据库存在，我似乎无法找到语法错误。任何一双新鲜的眼睛都会有所帮助！

由于缺少查询参数或对插入的数据进行卫生处理，最可能的罪魁祸首是注入值时形成的错误字符串。请参阅下面的帖子，了解如何使用SqlLiteCommand参数的示例。
How to add parameters to a Sqllitecommand
我们会像Ehsan所说，需要看到最后的字符串，以确保这是真正的罪魁祸首。

尝试简化问题。而不是插入10个用户，标题，子评价和评论，只需做一个。更好的是，只是尝试插入单个用户而不是其他任何东西。如果这样做只是做一个标题，依此类推，直到你再次遇到这个错误。
然后，您将需要更少的代码来查看和检查以找到您的错误

想出来！其中一个字符串包含＆＃39;，这就是抛出错误。感谢@Ron Bayer和@Travis，这使我朝着正确的方向发展。
