我使用夏普體系結構1.6 VS2010並調查使用GUID 但我遇到了一個我一直無法解決的錯誤。使用GUID的夏普體系結構
Person實體
using System;
using NHibernate.Validator.Constraints;
using SharpArch.Core.DomainModel;
namespace SharpDemo.Core
{
public class Person : EntityWithTypedId<Guid>
{
[NotNullNotEmpty(Message = "First name must be provided.")]
public virtual string FirstName { get; set; }
[NotNullNotEmpty(Message = "Last name must be provided.")]
public virtual string LastName { get; set; }
}
}
流利的映射
using FluentNHibernate.Automapping;
using FluentNHibernate.Automapping.Alterations;
using SharpDemo.Core;
namespace SharpDemo.Data.NHibernateMaps
{
public class PersonMap : IAutoMappingOverride<Person>
{
public void Override(AutoMapping<Person> mapping)
{
mapping.Schema("dbo");
mapping.Table("People");
mapping.Id(x => x.Id).GeneratedBy.GuidComb();
}
}
}
該解決方案成功生成,但遇到下面的錯誤,當 調試(我一直無法解析)。任何幫助是 讚賞。

感謝您的反饋。當我追加.Default(Guid.Empty)時遇到了同樣的錯誤,但它引導我嘗試.UnsavedValue(Guid.NewGuid()),這似乎解決了問題。謝謝詹姆斯。 – Tyler 2010-12-23 16:48:59
