EF Code First Fluent API - 级联删除 [英] EF Code First Fluent API - Cascade Delete

问题描述

我有两个模型：

public class User
{
   .....
   public virtual UserProfile UserProfile { get; set;}
}


public class UserProfile
{
   .....
   public virtual User User { get; set;}
}

用户是主表，关系是一对一的。一个用户只有一个UserProfile。

The User is the master table and the relation is one to one. One user has only one UserProfile.

如何使用EF CodeFirst Fluent API定义User和UserProfile之间的关系，以便当我从User表中删除一个用户时Userprofile的用户配置文件也被删除？

How can I define the relationship between User and UserProfile using EF CodeFirst Fluent API in such a way that when I delete one user from User table the user profile from Userprofile is also deleted?

推荐答案

使用 WillCascadeOnDelete

modelBuilder.Entity<UserProfile>()
    .HasKey(c => c.Id)
    .HasRequired(c => c.User)
    .WithRequiredDependent(c => c.UserProfile)
    .WillCascadeOnDelete(true);
