Question

我有一个类，我想在数据库中创建一个表

namespace WCG.Data.EntityObjects
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.ComponentModel.DataAnnotations;


   /// <summary>
    /// Class to access  FaxHistory Table
    /// </summary>

     public class FaxHistory
    {

         public virtual int Id { get; set; }
        // public virtual bool display { get; set; }
         public virtual bool IsDeleted { get; set; }
        [Required(ErrorMessage = "Fax History Date is required.")]
        [Display(Name = "Fax History Date")]
     public virtual DateTime FaxHistDate { get; set; }
        [Required(ErrorMessage = "Fax History to Text is required.")]
        [Display(Name = "Fax History To Text")]
     public virtual string FaxHistToText {get;set;}
        [Required(ErrorMessage = "Fax History NumText is required.")]
        [Display(Name = "Fax History NumText")]
     public virtual string FaxHistNumText {get;set;}
        [Required(ErrorMessage = "Fax History From Text is required.")]
        [Display(Name = "Fax History From Text")]   
     public virtual string FaxHistFromText {get;set;}
        [Required(ErrorMessage = "Fax History ReText is required.")]
        [Display(Name = "Fax History ReText")]
     public virtual string FaxHistREText{get;set;}
        [Required(ErrorMessage = "Fax History CmtText is required.")]
        [Display(Name = "Fax History CmtText")]
     public virtual string FaxHistCmntText { get; set; }
        [Required(ErrorMessage = "Fax History Filename is required.")]
        [Display(Name = "Fax History Filename")]
     public virtual string FaxHistFilenameText { get; set;}

        public virtual DateTime DateCreated { get; set; }

        public virtual DateTime DateModified { get; set; }

        public virtual string CreatedBy { get; set; }

        public virtual string ModifiedBy { get; set; }


    }
}

NHibernate映射文件是FaxHistory.hbm.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Data"  namespace="WCG.Data.EntityObjects">
  <class name="FaxHistory" table="FaxHistory">
    <id name="Id" column="Id" type="System.Int32">
      <generator class="identity" />
    </id>
    <property name="FaxHistDate" column="FaxHistDate" type="System.DateTime" />
    <property name="FaxHistToText" column="FaxHistToText" type="System.String" insert="true" update="true"/>
    <property name="FaxHistNumText" column="FaxHistNumText" type="System.String" insert="true" update="true"/>
    <property name="FaxHistFromText" column="FaxHistFromText" type="System.String" insert="true" update="true"/>
    <property name="FaxHistREText" column="FaxHistREText" type="System.String" insert="true" update="true"/>
    <property name="FaxHistCmntText" column="FaxHistCmntText" type="System.String" insert="true" update="true"/>
    <property name="FaxHistFilenameText" column="FaxHistFilenameText" type="System.String" insert="true" update="true"/>
    <property name="DateCreated" column="DateCreated" type="System.DateTime" insert="true" update="false"/>
    <property name="DateModified" column="DateModified" type="System.DateTime" insert="true" update="true"/>
    <property name="CreatedBy" column="CreatedBy" type="System.String" insert="true" update="false"/>
    <property name="ModifiedBy" column="ModifiedBy" type="System.String" insert="true" update="true"/>
    <property name="IsDeleted" column="IsDeleted" type="System.Boolean"  />
  </class>
</hibernate-mapping>

但是当我尝试在表单的帮助下将某些数据添加或更新到表中时，我收到错误

No persister for: WCG.Data.EntityObjects.FaxHistory

看过很多关于这个主题的讨论，但由于我不熟悉NHibernate，所以无法得到任何帮助。
