ILSPY找出了出问题的那一段源码，但是，看不出哪里有原因，datarow明明次第五个元素时先有判断的。大招唤术——牛人们来帮我看看吧,找出具体是哪句代码出了问题，因为这个方式是没有参数的，而且是查询操作，而且查询语句是没有问题的（不然就报oracle错误了）。
而且，【索引超出了数组界限】这种情况出现在查询操作中，真心让我无语啊，所有数据都来源于数据库，假如期间数组大小出了问题，我想应该就是这一段代码的问题了。

来看看所抛出的异常：
1 索引超出了数组界限。
2 在 Oracle.ManagedDataAccess.Client.OracleDataReader.GetMinSchemaTable()
3 在 Oracle.ManagedDataAccess.Client.OracleDataReader.set_IsFillReader(Boolean value)
4 在 Oracle.ManagedDataAccess.Client.OracleDataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords)
5 在 Oracle.ManagedDataAccess.Client.OracleDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
6 在 System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable)
7 在 EdiSharp.Utility.Data.OracleManagedDbHelperBase.GetDataTable(String sql)
8 在 Cot_DataFactory.OracleDAL.OracleDBHelper.GetDataTable(String SQLString)
9 在 Cot_DataFactory.BLL.B_CtnDymanic.ChangeLYGTZW(String wt_no, String ctn, Int32 state, String strIODate)
10 在 Cot_DataFactory.BLL.B_CtnDymanic.FullCtnOut(String wt_no, String ctn, String ctn_type, String ctn_corp, String strIODate)
11 在 Cot_DataFactory.Handles.Sync_Empty_Ctn.Work()
显然不是Oracle数据库抛出的，而是这最后一个方法抛出的，就是那个
Oracle.ManagedDataAccess.Client.OracleDataReader.GetMinSchemaTable()方法，这个方法的源码就是上面的那段。
