C# nHibernate集只给出一个结果

我必须映射类：

<class name="Business.DomainObjects.Institutions.Institutions, Business.DomainObjects"
    table="Institutions" lazy="false" mutable="false" >
<id name="Id" access="field.camelcase-underscore" column="ID">
  <generator class="identity" />
</id>

<property name="Caption" type="String" access="field.camelcase-underscore" column="Name" not-null="true"/>
<property name="AddressLine" type="String" access="field.camelcase-underscore" column="AddressLine" not-null="true" />
<property name="Phone" type="String" access="field.camelcase-underscore" column="Phone" not-null="false" />
<set name="WorkTime" cascade="none" fetch="join">
  <key column="ID" not-null="true"/>
  <one-to-many class="Business.DomainObjects.Institutions.WorkHours, Business.DomainObjects"/>
</set>

机构映射类代码：

public class Institution
{
    private int _id = 0;
    private string _caption = null;
    private string _addressLine = null;
    private string _phone = null;
    private ICollection<WorkHours> _workTime = null;

    public Institution(){}
    public int Id { get { return _id; } internal set { _id = value; } }
    public string Caption { get { return _caption; } set { _caption = value; } }
    public string AddressLine { get { return _addressLine; } set { _addressLine = value; } }
    public string Phone { get { return _phone; } set { _phone = value; } }
    public ICollection<WorkHours> WorkTime { get { return _workTime; } set { _workTime = value; } }
}

公共类机构
{
私有int_id=0；
私有字符串_caption=null；
私有字符串_addressLine=null；
私有字符串_phone=null；
私有ICollection_workTime=null；
公共机构（）{}
公共int Id{get{return}Id；}内部集合{{u Id=value；}
公共字符串标题{get{return{u Caption；}set{{u Caption=value；}}
公共字符串地址行{get{return{U AddressLine；}集合{U AddressLine=value；}}
公共字符串Phone{get{return{u Phone；}set{{u Phone=value；}}
公共ICollection工作时间{get{return}u WorkTime；}set{{u WorkTime=value；}}
}

正如你们所看到的，我已经在机构课程中设置了，但当我选择时，我只得到一个工作时间记录，而应该有7个。它生成良好的sql并选择必要的记录，同时在ManagementStudio中执行。我试着用袋子代替布景，但我7次都得到了同样的记录。也许有人知道问题出在哪里

好的，我稍微更改了我的映射：

<class name="Business.DomainObjects.Institutions.Institutions, Business.DomainObjects"
    table="Institutions" lazy="false" mutable="false" >
<id name="Id" access="field.camelcase-underscore" column="InstitutionID">
  <generator class="identity" />
</id>

<property name="Caption" type="String" access="field.camelcase-underscore" column="Name" not-null="true"/>
<property name="AddressLine" type="String" access="field.camelcase-underscore" column="AddressLine" not-null="true" />
<property name="Phone" type="String" access="field.camelcase-underscore" column="Phone" not-null="false" />
<set name="WorkTime" cascade="none" fetch="join">
  <key column="InstitutionID" not-null="true"/>
  <one-to-many class="Business.DomainObjects.Institutions.WorkHours, Business.DomainObjects"/>
</set>

<class name="Business.DomainObjects.Institutions.WorkHours, Business.DomainObjects" 
table="WorkHours" lazy="false" mutable="false" >
<id name="Id" access="field.camelcase-underscore" column="WorkHoursID">
  <generator class="identity" />
</id>
<property name="Weekday" type="int" access="field.camelcase-underscore" column="Weekday" not-null="true" />
<property name="OpenFrom" type="DateTime" access="field.camelcase-underscore" column="OpenFrom" not-null="true" />
<property name="OpenTill" type="DateTime" access="field.camelcase-underscore" column="OpenTill" not-null="true" />
<property name="OpenTime" type="String" access="field.camelcase-underscore" column="OpenTime" not-null="true" />
<many-to-one name="Institution" class="Business.DomainObjects.Institutions.Institution, Business.DomainObjects" column="InstitutionID" />
</class>

但我仍然有同样的问题。

这看起来很可疑：

<key **column="ID"** not-null="true"/>

它应该映射到WorkHours表中的外键列，因此可能类似于InstitutionID的内容这看起来很可疑：

<key **column="ID"** not-null="true"/>

它应该映射到WorkHours表中的外键列，因此可能类似InstitutionID的内容看起来不正确：

Column=XX在这两种情况下，请参考工时表中的外键列。尝试类似Column=InstitutionID的方法，这些方法看起来不正确：

Column=XX在这两种情况下，请参考工时表中的外键列。试试Column=InstitutionID之类的方法，我发现了我的问题。我必须更改我的工作时间映射并添加此项

<composite-id access="field.camelcase-underscore">
  <key-many-to-one
      class="Business.DomainObjects.Institutions.Institution, Business.DomainObjects"
      name="Institution"
      column="InstitutionID"
      access="field.camelcase-underscore"
  />
  <key-property
      name="Weekday"
      type="int"
      access="field.camelcase-underscore"
      column="Weekday"
  />
</composite-id>

而不是：

<id name="Id" access="field.camelcase-underscore" column="WorkHoursID">
  <generator class="identity" />
</id>
<property name="Weekday" type="int" access="field.camelcase-underscore" column="Weekday" not-null="true" />

它现在工作得很好。

它现在运行得很好。

您是否将机构映射到WorkHours对象？你能给我们看看db表中的数据吗？我们也能看看你的映射类代码吗？你把机构映射到WorkHours对象了吗？你能给我们看看db表中的数据吗？我们也能看看你的映射类代码吗。
