C# Fluent NHibernate（ASP.NET MVC）中的枚举类型不匹配

表格型号：

public class UserOwnerShip
{
    public virtual int Id { get; set; }
    public virtual User User { get; set; }
    public virtual City City { get; set; }
    public virtual Company Company { get; set; }
    public virtual UserRole UserRole { get; set; }
    public virtual DateTime RegistryDate { get; set; }
    public virtual bool IsActive { get; set; }
}

映射：

internal class UserOwnerShipMap : ClassMap<UserOwnerShip>
{
    public UserOwnerShipMap()
    {
        Id(x => x.Id);
        Map(x => x.IsActive);
        Map(x => x.UserRole).CustomType(typeof(int));
        Map(x => x.RegistryDate);

        References(x => x.User).Not.Nullable();
        References(x => x.City).Nullable();
        References(x => x.Company).Nullable();
    }
}

以及我的nhibernate配置部分：

....().Conventions.AddFromAssemblyOf<EnumConvention>())

---

如果要存储枚举的int值，映射简单：

Map(x => x.UserRole).CustomType<UserRole>();

Map（x=>x.UserRole）.CustomType（）；

---

没有必要使用EnumConvention。

这比你想象的容易，但无法弥补困难，所以请享受这一次。

....().Conventions.AddFromAssemblyOf<EnumConvention>())

    IList<UserOwnerShip> userOwnerShip = session.QueryOver<UserOwnerShip>()
                                                    .Where(u => u.UserRole == UserRole.Owner)
                                                    .Where(u => u.IsActive)
                                                    .List<UserOwnerShip>();

Type mismatch in NHibernate.Criterion.SimpleExpression: UserRole expected type System.Int32, actual type XXX.XXX.UserRole (which is enum type class)

Map(x => x.UserRole).CustomType<UserRole>();
