你知道映射文件的问题在哪里吗?

Eroor:无法编译映射文件:NHibernateTutorial.Mapping.Character.hbm.xml

我添加我所有的文件。

特点

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace NHibernateTutorial.Domain
{
    public class Character
    {
        public virtual Guid Id { get; set; }
        public virtual string Name { get; set; }
        public virtual int HealthPoints { get; set; }
        public virtual int Mana { get; set; }
        public virtual string Profession { get; set; }
    }
}

映射(Character.hbm.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                   assembly="NHibernateTutorial"
                   namespace="NHibernateTutorial.Domain">

  <class name="Character">
    <id name="Id">
      <generator class="guid" />
    </id>
    <property name="Name" />
    <property name="HealthPoints" />
    <property name="Mana" />
    <property name="Profession" />
  </class>

</hibernate-mapping>

查看您的异常详细信息:

无法实例化方言类 NHibernate.Dialect.MsSql2012Dialect [...]

您的问题不在于映射,而在于您如何指定数据库服务器技术 (RDBMS) 方言。这可能是由于各种原因而发生的:

  • 您正在尝试使用您下载的 NHibernate 版本中不存在的方言:您是否拥有最新版本(3.0、3.1、3.2、3.3...?)。

  • 您在错误的地方或以错误的方式指定方言。

仔细检查您的配置以及您是否拥有最新版本的 NHibernate!

您是否在 VS 的属性中将映射文件 Character.hbm.xml 标记为嵌入式资源?
