I have seen similar questions (1, 2), but none of them discuss how to insert CSV files into SQLite. About the only thing I could think of doing is to use a CSVDataAdap
try this -Import/Export CSV from SQLite from C# code
you can create OleDbConnection to CSV file (just google it, it is very easy) then load rows to DataSet, then put that dataset into Sqlite by SqliteConnection. Few lines of code.
