ibatis.net：尽可能的使用匿名类型替换 Hashtable

一切尽在代码中

Hashtable 风格

         public Account GetByCustomIdAndAccountType(int customId, AccountType accountType)
         {
             var parms = new Hashtable()
             {
                 { "CustomId" , customId },
                 { "AccountType" , (int)accountType }
             };

             return Mapper
                 .Instance()
                 .QueryForObject<Account>(Constants.Account.GetByCustomIdAndAccountType, parms);
         }

匿名类型风格

         public Account GetByCustomIdAndAccountType(int customerId, AccountType accountType)
         {
             var parms = new
             {
                 customerId,
                 accountType
             };

             return Mapper
                 .Instance()
                 .QueryForObject<Account>(Constants.Account.GetByCustomIdAndAccountType, parms);
         }

优点

• 减少重复，如：customerId 只出现一次。
