如何在.net中的类的每个属性中附加附加信息 [英] How to attached additional information with each Property of class in .net

问题描述

我想创建一个业务实体.

我想在每个属性中存储其他信息

 公共  class  BE
   {
          double  REDEMP_FEE_MONTH { get ; 设置； }
          double  ADMINISTRATOR_FEE_BREAKPNT { get ; 设置； }
          double  ADMINISTRATOR_FEE_PCT { get ; 设置； }
          double  ADVISORY_FEE_BREAKPNT { get ; 设置； }
          double  ADVISORY_FEE_PCT { get ; 设置； }
          double  SERVICE_FEE_BREAKPNT {获取; 设置； }
          double  SERVICE_FEE_PCT { get ; 设置； }
          double  TRANSFER_AGENT_FEE_BREAKPNT { get ; 设置； }
          double  TRANSFER_AGENT_FEE_PCT { get ; 设置； }
          double  CUSTODIAN_FEE_BREAKPNT { get ; 设置； }
          double  CUSTODIAN_FEE_PCT { get ; 设置； }
          double  REDEMP_FEE_PCT { get ; 设置； }
          double  DISTRIBUTION_12B_FEE { get ; 设置； }
         字符串 FUND_STREET {获取; 设置； }
         字符串 FUND_CITY { get ; 设置； }
         字符串 FUND_STATE { get ; 设置； }
         字符串 PHONE_TOLLFREE {获取; 设置； }
         字符串 URL {获取; 设置； }
          double  BROKER_COMM_AMOUNT { get ; 集;}
   } 

我想为每个这些属性保留两个附加值"StartOffSet"和"EndOffSet"，类型为int.

可以帮忙一下吗.

谢谢，
HN Mishra

解决方案

如果要获取有关属性的其他元数据，则需要实现可应用的自定义属性以及使用该属性的所有必需代码. /blockquote>

这取决于两个附加值的含义.如果它们确实具有元数据的特征并且永远不会改变，则可以使用Mark提供的想法.

在其他情况下，您可以做得更简单:使用包含这两个参数的类型来代替基本类型.我建议应该是上课.在这种情况下，可以使用一个仅包含StartOffset和EndOffset的基于抽象的类.我不知道这些成员的含义，但是，从它们的名称进行猜测，我建议使用StartOffset和OffsetLength，以避免当"end"小于"start"时出现问题.

I want to create a business entity.

I want to store additional information with each property

public class BE
   {
         double REDEMP_FEE_MONTH { get; set; }
         double ADMINISTRATOR_FEE_BREAKPNT { get; set; }
         double ADMINISTRATOR_FEE_PCT { get; set; }
         double ADVISORY_FEE_BREAKPNT { get; set; }
         double ADVISORY_FEE_PCT { get; set; }
         double SERVICE_FEE_BREAKPNT { get; set; }
         double SERVICE_FEE_PCT { get; set; }
         double TRANSFER_AGENT_FEE_BREAKPNT { get; set; }
         double TRANSFER_AGENT_FEE_PCT { get; set; }
         double CUSTODIAN_FEE_BREAKPNT { get; set; }
         double CUSTODIAN_FEE_PCT { get; set; }
         double REDEMP_FEE_PCT { get; set; }
         double DISTRIBUTION_12B_FEE { get; set; }
         string FUND_STREET { get; set; }
         string FUND_CITY { get; set; }
         string FUND_STATE { get; set; }
         string PHONE_TOLLFREE { get; set; }
         string URL { get; set; }
         double BROKER_COMM_AMOUNT { get; set;}     
   }

I want to keep two additional values "StartOffSet" and "EndOffSet" of type int for each of these properties.

Can some one help.

Thanks,

解决方案

If you want additional metadata about the properties you will need to implement a custom attribute that can be applied and all requisite code to make use of it.

It depends on the meaning of the two additional value. If they are really have a character of meta-data and will never change, you can use the idea provided by Mark.

In other cases, you can do simpler thing: instead of primitive types use the types containing these two parameters. I would suggest the should be classes. In this case, you can use one abstract based class containing only StartOffset and EndOffset. I don''t know the meaning of these members, but, taking a guess from their name, I would suggest to use StartOffset and OffsetLength, to avoid problems when "end" is less then "start".
