NHibernate的：具有相同的精度和规模都小数地图

问题描述

据我了解，在NHibernate的，使用映射通过代码，我可以指定像这样一个十进制属性的精确度和规模：

I understand that in NHibernate, using mapping by code, I can specify the precision and scale of a decimal property like so:

Property(
    x => x.Dollars,
    m =>
        {
            m.Precision(9);
            m.Scale(6);
        }
 );

这是不错，但我不知道是否有办法，我可以很容易地映射的 ALL 在一个简单的方法在所有类别中的小数属性。这似乎那种疯狂，我将不得不通过我所有的映射，并通过手工更新它们。有谁知道如何可以做到这一点？

That is nice, but I was wondering if there was a way that I could easily map ALL of the decimal properties in all of the classes in an easy way. It seems kind of crazy that I would have to go through all of my mappings and update each of them by hand. Does anyone know how this can be achieved ?

推荐答案

使用 BeforeMapProperty 在ModelMapper： -

Use the BeforeMapProperty on the ModelMapper:-

var mapper = new ModelMapper();

mapper.BeforeMapProperty += (inspector, member, customizer) =>  {
    if (member.LocalMember.GetPropertyOrFieldType() == typeof (decimal))
    {
      customizer.Precision(9);
      customizer.Scale(6);
    }
};

唯一的其他东西补充的是删除所有出现： -

The only other thing to add is remove all occurrences of:-

 m => { m.Precision(9); m.Scale(6); }

这是因为这些将覆盖您约定设置映射类 BeforeMapProperty 除非你有不同的尺度或其他精度小数。

from your mapping classes as these will override your convention set in BeforeMapProperty unless you have other decimals that have different scales or precisions.
