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。
