SQL escape with sqlite in C#

Question

Answer 1

You should be using a parameter as in:

SQLiteCommand cmd = _connection.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT * FROM MyTable WHERE MyColumn = @parameter";
cmd.Parameters.Add( new SQLiteParameter( "@parameter", textfield ) );
SQLiteDataReader reader = cmd.ExecuteReader();

Using a parametrised SQL will escape all input values and help protect you from SQL injection attacks.

Answer 2

You can also replace all single quote delimiters with doubt single quotes (not ").

sql = sql.Replace("'","''");
