.NET Framework Data Provider for ODBC DRIVER=sqlite3 ODBC Driver; Database=mydb.db; LongNames=0; Timeout=1000; NoTXN=0; SyncPragma=NORMAL; StepAPI=0; This is just one connection string sample for the wrapping OdbcConnection class that calls the underlying ODBC Driver. See respective ODBC driver for more connection strings to use with this class. sqlite3 ODBC Driver DRIVER=sqlite3 ODBC Driver; Database=mydb.db; LongNames=0; Timeout=1000; NoTXN=0; SyncPragma=NORMAL; StepAPI=0; sqlite.NET Basic（基本的） Data Source=filename;Version=3; Using UTF16（使用UTF16编码） Data Source=filename;Version=3;UseUTF16Encoding=True; With password（带密码的） Data Source=filename;Version=3;Password=myPassword; Using the pre 3.3x database format（使用3.3x前数据库格式） Data Source=filename;Version=3;Legacy Format=True; Read only connection（只读连接） Data Source=filename;Version=3;Read Only=True; With connection pooling（设置连接池） Data Source=filename;Version=3;Pooling=False;Max Pool Size=100; Using DateTime.Ticks as datetime format（） Data Source=filename;Version=3;DateTimeFormat=Ticks; The default value is ISO8601 which activates the use of the ISO8601 datetime format Store GUID as text（把Guid作为文本存储，默认是Binary） Data Source=filename;Version=3;BinaryGUID=False; 如果把Guid作为文本存储需要更多的存储空间 Specify cache size（指定Cache大小） Data Source=filename;Version=3;Cache Size=2000; Cache Size 单位是字节 Specify page size（指定页大小） Data Source=filename;Version=3;Page Size=1024; Page Size 单位是字节 Disable enlistment in distributed transactions Data Source=filename;Version=3;Enlist=N; Disable create database behavIoUr（禁用创建数据库行为） Data Source=filename;Version=3;FailIfMissing=True; 默认情况下，如果数据库文件不存在，会自动创建一个新的，使用这个参数，将不会创建，而是抛出异常信息 Limit the size of database（限制数据库大小） Data Source=filename;Version=3;Max Page Count=5000; The Max Page Count is measured in pages. This parameter limits the maximum number of pages of the database. Disable the Journal File （禁用日志回滚） Data Source=filename;Version=3;Journal Mode=Off; This one disables the rollback journal entirely.
