Question

最近，我在UserMap类中添加了一个新列，以添加一个int数组

public class UserMap : ClassMap<User>
{
    public UserMap()
    {
        Table("user");
        LazyLoad();
        Id(x => x.Id).GeneratedBy.Identity().Column("Id");
        Map(x => x.DateCreated).Column("DateCreated").Not.Nullable();
        Map(x => x.Birthday).Column("Birthday").Nullable();
        Map(x => x.HideBirthday).Column("HideBirthday").Nullable();
        Map(x => x.Name).Column("Name").Not.Nullable();
        Map(x => x.Email).Column("Email").Not.Nullable();
        Map(x => x.PassWord).Column("Password").Not.Nullable();
        Map(x => x.NotificationCounter).Column("NotificationCounter").Nullable().Default("0");
        //EMAILPRIVACY = int[]
        Map(x => x.EmailPrivacy).Column("EmailPrivacy").Nullable();
    }
}

因此，我需要使用int数组向 EmailPrivacy 列添加默认值。

new int[] { 1, 2, 3, 4, 5, 6, 7 }

当我添加默认值时，我收到了错误：

Map(x => x.EmailPrivacy).Column("EmailPrivacy").Nullable().Default(new int[] { 1, 2, 3, 4, 5, 6, 7 }.ToString());

错误讯息：

Unknown column 'user0_.EmailPrivacy' in 'field list'

如何添加此int []默认值？
