Question

您知道映射文件的问题在哪里吗？

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

我添加了所有文件。

字符

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>

Answer 1

查看您的例外情况：

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。这可能是因为各种原因：

您正在尝试使用下载的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 ......？）。 < / p>
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是否有最新版本的NHibernate！

Answer 2

您是否已将映射文件Character.hbm.xml标记为VS？

属性中的嵌入资源

错误的映射NHibernate 3.3
