ArgumentOutOfRangeException：索引超出範圍

無論何時我使用 PersitenceSpecification類驗證對值對象具有引用的實體，我都會收到此奇怪的ArgumentOutOfRangeException。ArgumentOutOfRangeException：索引超出範圍

public class CatalogItem : DomainEntity 
    { 
     internal virtual Manufacturer Manufacturer { get; private 
set; } 
     internal virtual String Name { get; private set; } 

     protected CatalogItem() 
     {} 

     public CatalogItem(String name, String manufacturer) 
     { 
      Name = name; 
      Manufacturer = new Manufacturer(manufacturer); 
     } 
    } 

    public class CatalogItemMapping : ClassMap<CatalogItem> 
    { 
     public CatalogItemMapping() 
     { 
      Id(catalogItem => catalogItem.Id); 

      Component<Manufacturer>(category => category.Manufacturer, 
            m => m.Map(manufacturer => 
manufacturer.Name)); 

      Map(catalogItem => catalogItem.Name); 
      Map(Reveal.Property<CatalogItem>("Price")); 
     } 
    } 

    [TestFixture] 
    public class When_verifying_the_class_mapping_of_a_catalog_item 
     : NHibernateSpecification 
    { 
     [Test] 
     public void Then_a_catalog_object_should_be_persistable() 
     { 
      new PersistenceSpecification<CatalogItem>(Session) 
       .VerifyTheMappings(); 
     } 
    } 

    [TestFixture] 
    public class NHibernateSpecification 
     : Specification 
    { 
     protected ISession Session { get; private set; } 

     protected override void Establish_context() 
     { 
      var configuration = new SQLiteConfiguration() 
       .InMemory() 
       .ShowSql() 
       .ToProperties(); 

      var sessionSource = new SessionSource(configuration, new 
RetailerPersistenceModel()); 
      Session = sessionSource.CreateSession(); 

      sessionSource.BuildSchema(Session); 
      ProvideInitialData(Session); 

      Session.Flush(); 
      Session.Clear(); 
     } 

     protected override void Dispose_context() 
     { 
      Session.Dispose(); 
      Session = null; 
     } 

     protected virtual void ProvideInitialData(ISession session) 
     {} 
    }

這裏是我得到的錯誤：

的TestCase 'Then_a_catalog_object_should_be_persistable' 不執行： System.ArgumentOutOfRangeException：指數超出範圍。必須爲非負值且小於的大小。參數名：指數在System.ThrowHelper.ThrowArgumentOutOfRangeException （ExceptionArgument說法， ExceptionResource資源）在System.ThrowHelper.ThrowArgumentOutOfRangeException（）在System.Collections.Generic.List 1.get_Item(Int32 index) at System.Data.SQLite.SQLiteParameterCollection.GetParameter(Int32 index) at System.Data.Common.DbParameterCollection.System.Collections.IList.get_Item (Int32 index) at NHibernate.Type.GuidType.Set(IDbCommand cmd, Object value, Int32 index) at NHibernate.Type.NullableType.NullSafeSet(IDbCommand cmd, Object value, Int32 index) at NHibernate.Type.NullableType.NullSafeSet(IDbCommand st, Object value, Int32 index, ISessionImplementor session) at NHibernate.Persister.Entity.AbstractEntityPersister.Dehydrate (Object id, Object[] fields, Object rowId, Boolean[] includeProperty, Boolean[][] includeColumns, Int32 table, IDbCommand statement, ISessionImplementor session, Int32 index) at NHibernate.Persister.Entity.AbstractEntityPersister.Insert(Object id, Object[] fields, Boolean[] notNull, Int32 j, SqlCommandInfo sql, Object obj, ISessionImplementor session) at NHibernate.Persister.Entity.AbstractEntityPersister.Insert(Object id, Object[] fields, Object obj, ISessionImplementor session) at NHibernate.Action.EntityInsertAction.Execute() at NHibernate.Engine.ActionQueue.Execute(IExecutable executable) at NHibernate.Engine.ActionQueue.ExecuteActions(IList list) at NHibernate.Engine.ActionQueue.ExecuteActions() at NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions (IEventSource session) at NHibernate.Event.Default.DefaultFlushEventListener.OnFlush (FlushEvent event) at NHibernate.Impl.SessionImpl.Flush() at NHibernate.Transaction.AdoTransaction.Commit() d:\Builds\FluentNH\src\FluentNHibernate\Testing \PersistenceSpecification.cs(127,0): at FluentNHibernate.Testing.PersistenceSpecification 1.TransactionalSave （對象的PropertyValue） d： \構建\ FluentNH \ SRC \ FluentNHibernate \測試 \ PersistenceSpecification.cs（105,0）：在 FluentNHibernate.Testing.PersistenceSpecification`1.VerifyTheMappings （） C：\源\供應鏈\測試\ Retailer.IntegrationTests \映射 \ CatalogItemMappingSpecifications.cs（14,0）：在 SupplyChain.Retailer.IntegrationTests.Mappings.When_verifying_the_class_mapping_of_a_catalog_item.Then_a_catalog_object_should_be_persistable （）

很抱歉的長期職位，但是這一次讓我忙了幾個小時現在。

我仍然希望我做錯了什麼在我的代碼:-)：這可能不是FNH因爲我發現NH本身的這個JIRA票即提到類似的情況引起。任何想法？

在此先感謝

我找到了解決這個問題的方法，這個問題首先是由我自己的愚蠢造成的。 I 從流利的NH映射中生成了hbm文件，這一切都變得清晰起來。

<class name="CatalogItem" table="`CatalogItem`" xmlns="urn:nhibernate- 
mapping-2.2" optimistic-lock="version"> 
    ... 

    <property name="Name" length="100" type="String"> 
     <column name="Name" /> 
    </property> 

    ... 

    <component name="Manufacturer" insert="false" update="true"> 
     <property name="Name" length="100" type="String"> 
     <column name="Name" /> 
     </property> 
    </component> 
    </class>

注意，Name屬性和用於廠商組件列的列都被映射到相同的列中。這就是爲什麼這導致了一個ArgumentOutOfRangeException，因爲有更多的參數比列名稱。我解決了這個由爲組件映射明確地指定列名：

組分（catalogItem => catalogItem.Manufacturer，米=> m.Map（製造商=> manufacturer.Name，「製造商」））;

另一個教訓。
