how to read places.sqlite of firefox using c# application

Hi I am trying to get all history url of mozilla firefox. To do that I am accessing places.sqlite file inside %appdata%mozilla/firefox/profile/*.default folder. I am using system.data.sqlite dll in my code and tried x64 and x86 both of the solution. As I am trying to connect the database it is showing me an exception that the file is encrypted or not a database file. To cross check this exception I've installed a dbmanager for sqlite and opened it. This is showing me all the data that I want to show. But I am not able to get the same data using c# application. Please Help me to get this thing resolved.

SQLiteConnection sqlite_connection = new SQLiteConnection("Data Source=" + dbPath + ";Version=3;New=True;Compress=True;Integrated Security=SSPI;");

            SQLiteCommand sqlite_command = sqlite_connection.CreateCommand();

            sqlite_connection.Open();// exception occurs here
