Question

public class Parent
{
    public virtual int Id{ get; set; }
    public virtual ICollection<Child> Children { get; set; }
    public Parent()
    {
        Children = new List<Child>();
    }
}
public class Child
{
    public virtual int Id{ get; set; }
    public virtual string Name { get; set; }
}

映射：

public ParentMap()
{
        Map(x => x.Number).Not.Nullable();
        HasMany(x => x.Children)
            .Cascade.None()
            .KeyColumn("ParentId")
            .ExtraLazyLoad()
            .AsSet();
}

生成的Sql脚本：

ALTER TABLE [dbo].[Child]  WITH CHECK ADD  CONSTRAINT [FKFCFBAA864983AA6A] FOREIGN KEY([ParentId])
REFERENCES [dbo].[Parent] ([Id])
GO
ALTER TABLE [dbo].[Child] CHECK CONSTRAINT [FKFCFBAA864983AA6A]
GO

如何将[FKFCFBAA864983AA6A]的外键格式更改为[FK_ChildTableName_ParentTableName]？

感谢@Rabban评论，.ForeignKeyConstraintName("FK_MyKey")就是诀窍。

用于制图，

public ParentMap()
{
        Map(x => x.Number).Not.Nullable();
        HasMany(x => x.Children)
            .Cascade.None()
            .KeyColumn("ParentId")
            .ForeignKeyConstraintName("FK_Children_Parent") //customize Foreign Key name
            .ExtraLazyLoad()
            .AsSet();
}
