Nhibernate Named Query 问题（100分，分不够在加）

Question

代码如下：DAO层                try
                {
                    IQuery queryObject = session.GetNamedQuery(_queryName);
                    if (_values != null)
                    {
                        for (int i = 1; i <= _values.Length; i++)
                        {
                            queryObject.SetParameter(i, _values[i-1]);
                        }
                    }
                    return queryObject.List();
                }
                catch (QueryException ex)
                {
                    return null;
                }测试代码入下：
         [Test]
        public void FindByNameQueryByEmployeeCode()
        {
            object[] values = { "Lubo" };
            IList list = employeeDao.FindByNamedQuery("GetEmployeeByEmployeeCode","Lubo");
            System.Console.WriteLine(list.Count);
        }测试过程中：
异常入下：
 IndexOutOfRangeException
 "Remember that ordinal parameters are 1-based!"

Answer 1

queryObject.SetParameter(i, _values[i-1]); 
是不是写成
queryObject.SetParameter(i-1, _values[i-1]); 

Answer 2

Named Query定义如下： <query name="GetEmployeeByEmployeeCode">
   <![CDATA[from PanGu.Net.Test.Data.Employee employee where employee.EmployeeCode = :EmployeeCode]]>
 </query>

Answer 3

<query name="GetEmployeeByEmployeeCode">
    <![CDATA[from PanGu.Net.Test.Data.Employee employee where employee.EmployeeCode = ?]]>
  </query>

Answer 4

               try
                {
                    IQuery queryObject = session.GetNamedQuery(_queryName);
                    if (_values != null)
                    {
                        for (int i = 0; i <_values.Length; i++)
                        {
                            queryObject.SetParameter(i, _values[i]);
                        }
                    }
                    return queryObject.List();
                }
                catch (QueryException ex)
                {
                    System.Console.WriteLine(ex.Message);
                    return null;
                }
