EF4从SQL Server char(1)创建自定义映射到bool ???? [英] EF4 Create custom mapping from SQL Server char(1) to bool ????
问题描述
我已经阅读了大量关于地图的文章。 尝试做一个基本的事情,比如将SQL Char(1)字段映射到C#布尔属性,这真的很常见。 感到惊讶的是,没有更多将SQL数据类型映射到C#类型的示例在这里
I've read tons of articles on mapping. Trying to do a basic thing like map a SQL Char(1) field to a C# boolean property, which is really really common. Surprised there are not more examples of mapping SQL datatypes to C# types up here
:) 希望这很容易???

推荐答案
Hi Marty,
Hi Marty,
在这个阶段,这在EF中是不可能的,我们计划在将来为您的模型和CLR对象之间的映射提供一些可扩展性发布(这将支持这种情况)。目前最好的解决方法是添加第二个属性
进行读/写转换。
This isn't possible in EF at this stage, we do plan to provide some extensibility for mapping between your model and CLR objects in a future release (which would support this scenario among others). For the moment the best workaround is to add a second property that does the read/write conversion.
