我在使用 nhibernate 执行存储过程时遇到了奇怪的问题。当我通过堆栈跟踪时，我得到了 Index Out Of Range 异常和属性/列的名称。我对 google 和 stackoverflow 进行了研究，发现如果任何属性被映射两次，则会导致问题。我检查了所有映射，但似乎对我没有任何帮助。在这里，我正在编写我正在使用的所有 hbl 文件和代码。

我正在使用以下代码调用 sp。

                       .SetParameter("CustomerActive", 2)
                       .SetParameter("CompanyID", Guid.Parse("3C5F1D66-75F3-4762-BAA1-6A0ADA8D6DD4"))
                       .SetParameter("PropertyID", Guid.Parse("53C4B765-C1B1-4353-98CB-AC9FBCE84F0C"))
                       .SetParameter("DateFrom", DateTime.Parse("5/1/2001"))
                       .SetParameter("DateTo", DateTime.Parse("4/24/2013"))
                       .SetParameter("InvoiceTypes", "Manual")
                       .SetResultTransformer(new AliasToBeanResultTransformer(typeof(tARCustomer)))
                       .SetResultTransformer(Transformers.ToList).List();

除了我尝试了很多组合但我无法解决它。我有以下存储过程。

alter PROCEDURE [dbo].[ar_tARCustomer_ReadOverdueByContext]  

  @CustomerActive  int,      
  @CompanyID   uniqueidentifier,   
  @PropertyID   uniqueidentifier,   
  @OverdueDateFrom  datetime,   
  @OverdueDateTo  datetime,   
  @InvoiceTypes   varchar(100)  

AS  

----------------------------------------------------------------------------    
-- Name:     ar_tARCustomer_ReadOverdueByContext    
-- Purpose:  Get all customers with overdue invoices matching the given criteria at this point in the hierarchy       
--    
-- Input:    N/A    
-- Output:   Recordset containing all customers with overdue invoices matching the given criteria  
-- Return:   0 = Success    
--           >0 = Error    
--    
----------------------------------------------------------------------------    

SET NOCOUNT ON;  -

SELECT fName
from tARCustomer

我想说的另一件事是，当我使用 select * from tARCustomer 时，此过程对我有用，但是当我使用 select fCustomerID from tARCustomer 时，它会出错。

我不知道为什么会发生，但无法解决。请帮我尽快解决这个问题，

在这里，我放置异常的堆栈跟踪。

当您AliasToBeanResultTransformer在查询结果上使用时，查询中返回的列必须与您正在加载数据的类的属性一一对应。

您在上面发布的查询仅返回一列fName1- 它缺少您的类的所有其他属性tARCustomer。

抛出的异常告诉您问题 - 它找不到结果列fCustomerID。为了说明修改您的 select 语句以包含它并重新运行它，异常将突出显示下一个缺少的字段。
