更改导航属性的默认列名

尝试使用MapKey():

modelBuilder.Entity<TreeItem>()
            .HasRequired(it => it.Tree)
            .WithMany()
            .Map(m => m.MapKey("tree_id"));

编辑

here :

modelBuilder.Entity<TreeItem>()
            .Property<long>("TreeId")
            .HasColumnName("tree_id");

当两个实体相互关联时,我总是使用虚拟对象。执行此操作时,还可以按以下方式指定FK的列名:

public class TreeItem
{
    public long Id { get; set; }
    [Column("tree_id")]
    public int TreeId { get; set; }
    [ForeignKey("TreeId")]
    public virtual Tree Tree { get; set; }
    public string Model { get; set; }
    public string Version { get; protected set; }
    public string Index { get; protected set; }
}

public class Tree
{
    public int Id { get; set; }
    public string Name { get; set; }
}
