禁用 SQLite 自动创建数据库 - C#

Disable SQLite automatic Database creation - C#

我成功地使用了 try - catch 方法来测试 C# 与常见数据库的连接。 但是,对于 SQLite,当未检测到数据库时,它会创建一个新的数据库,这在我的情况下是不需要的。 “当您连接到一个不存在的 SQLite 数据库文件时,SQLite 会自动为您创建新的数据库”

SQLiteDataAdapter ad;
        DataTable dt = new DataTable();
        try
        {
            sqlite = new SQLiteConnection("Data Source=C:/Users/SKUL/Desktop/db/PatHist.db");
            SQLiteCommand cmd;
            sqlite.Open();  //Initiate connection to the db
            cmd = sqlite.CreateCommand();
            //-----------------
          
            picConnectionStatus.Image = Properties.Resources.icons8_database_view_64;
            lblConnectionEstablished.Text = "Connection Established";

            sqlite.Close();
           
        }
        catch (Exception ex)
        {
            picConnectionStatus.Image = Properties.Resources.icons8_delete_database_64;
            lblConnectionEstablished.Text = "Connection Error";
            lblConnectionEstablished.ForeColor = System.Drawing.Color.Red;
           
        }

需要的是禁用自动数据库创建和触发“捕获”例程的某种方式

在@Rafael 的建议下,我检查了文件是否存在。这样做问题就解决了。

if (System.IO.File.Exists(@"C:\Users\SKUL\Desktop\db\nPatHist.db"))
            {
               sqlite = new SQLiteConnection("Data Source=C:\Users\SKUL\Desktop\db\PatHist.db");
                SQLiteCommand cmd;
                sqlite.Open();  //Initiate connection to the db
                cmd = sqlite.CreateCommand();
                //-----------------

                picConnectionStatus.Image = Properties.Resources.icons8_database_view_64;
                lblConnectionEstablished.Text = "Connection Established";


                sqlite.Close();
            }
