将自定义属性添加到客户端实体类 [英] Adding custom property to Client Side Entity class

问题描述

我需要向Entity Framework类添加自定义属性，但是当我这样做时，我得到为类型XXX指定的属性名称XXX无效."错误.我可以给该属性提供一些属性，以便将其忽略并且不映射到任何东西吗?

I need to add a custom property to an Entity Framework class, however when I do I get the "The property name XXX specified for type XXX is not valid." error. Is there some attribute I can give the property so it is ignored and not mapped to anything?

如果我添加一个自定义属性(如下面的马丁示例所示)，则以下代码将在SaveChanges调用中引发上述错误.

If I add a custom property, as per Martin's example below, then the following code will raise the above error at the SaveChanges call.

MyEntities svc = new MyEntities(url);
MyEntity ent = new MyEntity();
ent.MyField = "Hello, world";
svc.AddMyEntity(ent);
svc.SaveChanges();
