概述:

     当用Nhibernate操作主从表时,往主表插入数据时,当执行到提交事务时出现如下错误:

此 OracleParameterCollection 的 Count=4 的索引 4 无效。

在 System.Data.OracleClient.OracleParameterCollection.RangeCheck(Int32 index) 在 System.Data.OracleClient.OracleParameterCollection.GetParameter(Int32 index) 在 System.Data.Common.DbParameterCollection.System.Collections.IList.get_Item(Int32 index) 在 NHibernate.Type.DecimalType.Set(IDbCommand st, Object value, Int32 index) 在 NHibernate.Type.NullableType.NullSafeSet(IDbCommand cmd, Object value, Int32 index) 在 NHibernate.Type.NullableType.NullSafeSet(IDbCommand st, Object value, Int32 index, ISessionImplementor session) 在 NHibernate.Persister.Entity.AbstractEntityPersister.Dehydrate(Object id, Object[] fields, Object rowId, Boolean[] includeProperty, Boolean[][] includeColumns, Int32 table, IDbCommand statement, ISessionImplementor session, Int32 index) 在 NHibernate.Persister.Entity.AbstractEntityPersister.Insert(Object id, Object[] fields, Boolean[] notNull, Int32 j, SqlCommandInfo sql, Object obj, ISessionImplementor session) 在 NHibernate.Persister.Entity.AbstractEntityPersister.Insert(Object id, Object[] fields, Object obj, ISessionImplementor session) 在 NHibernate.Action.EntityInsertAction.Execute() 在 NHibernate.Engine.ActionQueue.Execute(IExecutable executable) 在 NHibernate.Engine.ActionQueue.ExecuteActions(IList list) 在 NHibernate.Engine.ActionQueue.ExecuteActions() 在 NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions(IEventSource session) 在 NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) 在 NHibernate.Impl.SessionImpl.Flush() 在 NHibernate.Transaction.AdoTransaction.Commit() 在 DataAccess.DictateDao.AddRecord(String registerOrgid, String registerOperatorid, String dictateTitle, String dictateContent, String dictateType, String[] informOrgid, String[] accessoryName, String[] accessorySize) 位置 D:\OA\DataAccess\DataAccess\DictateDao.cs:行号 64

主程序如下:

Code
 public static bool AddRecord(string registerOrgid, string registerOperatorid, string dictateTitle, string dictateContent, string dictateType, string[] informOrgid, string[] accessoryName, string[] accessorySize)

            bool IsSuccess = false;
            string dictateID ="";
            JkptOaxtDictate od = new JkptOaxtDictate();
            JkptOaxtDictatedetails detail = new JkptOaxtDictatedetails();       




            
            ITransaction trans = session.BeginTransaction();
    
            try
            {              
               
                    od.Registerorgid = decimal.Parse(registerOrgid);
                    od.Registeroperatorid = registerOperatorid;
                    od.Registertime = DateTime.Now.ToLocalTime();
                    od.Dictatetitle = dictateTitle;
                    od.Dictatedesc = dictateContent;
                    od.Informtype = decimal.Parse(dictateType);
                    od.Modifytime = DateTime.Now.ToLocalTime();
                    od.Browsetime = DateTime.Now.ToLocalTime();

 

                    for (int i = 0; i < informOrgid.Length; i++)
                    {                    
                        
                        detail.Dictateid = decimal.Parse("3");
                        detail.Targetorgid = decimal.Parse(informOrgid[i]);
                        detail.Sign = 0;
                        detail.dictate = od;
                        od.details.Add(detail);
                        session.Save(od);
                                   
                    }
          
                        trans.Commit();              
              
 //写日志
                Helpers.SaveInfo("Insert dictate 's  infomation Success!");
                IsSuccess = true;
            }
            catch (Exception ex)
            {
                IsSuccess = false;

                trans.Rollback();
              
                
                //写日志
                Helpers.SaveInfo("插入失败！错误提示如下：" + ex.Message);
            }
            finally
            {
                if (session != null)
                {
                    session.Clear();
                }
            }
            return IsSuccess;
        }

当执行到trans.Commit()时出现如上所述错误.
