基于Sqlite和Sql Server中的嵌套事务--TransactionScrope

基于Sqlite：

public void AddTran(LogisInfo.Model.Advertiser model)
        {
            //事务行为的附加信息
            TransactionOptions tranOption = new TransactionOptions();
            tranOption.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
            tranOption.Timeout = new TimeSpan(0, 2, 0);

            try
            {
                //事务
                using (TransactionScope tranScope = new TransactionScope(TransactionScopeOption.RequiresNew, tranOption))
                {
                    //连接字符串
                    string connStr = DbHelperSQLite.ConnectionString;
                    if (connStr == null || connStr.Length == 0)
                    {
                        throw new ArgumentNullException("连接字符串为空！");
                    }

                    //保证基于同一个连接管道
                    using (SQLiteConnection conn = new SQLiteConnection(connStr))
                    {
                        int advertiserID = 0;

                        //一.添加广告商
                        using (SQLiteCommand cmd = new SQLiteCommand(conn))
                        {

                            StringBuilder strSql = new StringBuilder();

                            //打开连接，紧接着执行命令
                            if (conn.State == ConnectionState.Closed)
                            {
                                conn.Open();
                            }
                            advertiserID = Convert.ToInt32(cmd.ExecuteScalar());
                        }

                        //二.添加广告商图片
