EF代码首先防止使用Fluent API进行属性映射 [英] EF Code First prevent property mapping with Fluent API

问题描述

我有一个类产品和复杂类型 AddressDetails

I have a class Product and a complex type AddressDetails

public class Product
{
    public Guid Id { get; set; }

    public AddressDetails AddressDetails { get; set; }
}

public class AddressDetails
{
    public string City { get; set; }
    public string Country { get; set; }
    // other properties
}

是否可以防止映射国家财产从 AddressDetails 里面产品类？ （因为我不会需要它产品类）

Is it possible to prevent mapping "Country" property from AddressDetails inside Product class? (because i will never need it for Product class)

这样的一个

Property(p => p.AddressDetails.Country).Ignore();

推荐答案

对于EF5及更旧版本：
在 DbContext.OnModelCreating 覆盖您的上下文中：

For EF5 and older: In the DbContext.OnModelCreating override for your context:

modelBuilder.Entity<Product>().Ignore(p => p.AddressDetails.Country);

对于EF6：你没有运气。请参阅 Mrchief的回答。

For EF6: You're out of luck. See Mrchief's answer.
