• 学习NHibernate遇到的问题


    在写NHibernate的时候,遇到了:
    未能加载文件或程序集“NHibernateDemoWebSite”或它的某一个依赖项。系统找不到指定的文件
    以下是错误提示代码:
     1行 31:         //    .AddDirectory(new System.IO.DirectoryInfo(HostingEnvironment.MapPath("~/App_Data/")));
     2行 32
     3行 33:         config = new NHibernate.Cfg.Configuration().AddAssembly("NHibernateDemoWebSite");
     4行 34
     5行 35:         //.SetDefaultAssembly(typeof(TUserInfo).Assembly.FullName)

    以下是我写的一部分代码:
    DataAccessFactory.cs
     1using System;

    11using NHibernate;
    12using NHibernate.Cfg;
    13using NHibernateDemoWebSite;
    14
    15/// <summary>

    18public class DataAccessFactory : HttpApplication

    21    public static readonly NHibernate.Cfg.Configuration config;
    22    public static readonly NHibernate.ISessionFactory sessionFactory;
    23
    24    static DataAccessFactory()
    25    {
    26        //log4net.Config.XmlConfigurator.Configure();
    27        //config = new NHibernate.Cfg.Configuration();
    28        //Console.Write(typeof(TUserInfo).Assembly.FullName);
    29        //config.SetDefaultAssembly(typeof(TUserInfo).Assembly.FullName)

    34
    35        //.SetDefaultAssembly(typeof(TUserInfo).Assembly.FullName)
    36        //.SetDefaultNamespace(typeof(TUserInfo).Namespace)

    43
    44        sessionFactory = config.BuildSessionFactory();
    45    }

    46
    47    public static ISession GetCurrenSession()
    48    {
    49        return sessionFactory.GetCurrentSession();
    50    }

    51}

    注:注释部分是NHibernate源码里的Demo,我按照他的做法,但是还是出现了这样的问题

    以下是实体类:
      1//TUserInfo.cs
      2
      3using System;
      4using System.Collections;
      5using System.Web.UI.WebControls;
      6
      7namespace NHibernateDemoWebSite
      8{
      9    TUserInfo
    615}

    616
