c#sqllite建表

            //創建一個數據庫文件   
            string datasource = "E:/test1.db";
            System.Data.SQLite.SQLiteConnection.CreateFile(datasource);
            //連接數據庫   
            System.Data.SQLite.SQLiteConnection conn = new System.Data.SQLite.SQLiteConnection();
            System.Data.SQLite.SQLiteConnectionStringBuilder connstr = new System.Data.SQLite.SQLiteConnectionStringBuilder();
            connstr.DataSource = datasource;
            //connstr.Password = "admin";//設置密碼，SQLite ADO.NET實現了數據庫密碼保護
            conn.ConnectionString = connstr.ToString();
            conn.Open();
            //創建表   
            System.Data.SQLite.SQLiteCommand cmd = new System.Data.SQLite.SQLiteCommand();
            string sql = "CREATE TABLE test(username varchar(20),password varchar(20))";
            cmd.CommandText = sql;
            cmd.Connection = conn;
            cmd.ExecuteNonQuery();
