實例化對象OracleDate

所以我的代碼看起來像 -實例化對象OracleDate

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using Oracle.DataAccess.Client; 
using Oracle.DataAccess.Types; 

namespace OraDateTest { 
    public partial class _Default: System.Web.UI.Page { 
     protected void Page_Load(object sender, EventArgs e) { 
      OracleDate testdate1 = new OracleDate(); 

      String newdate = String.Format("{0:dd-MMM-yy}", DateTime.Parse("1/1/2001")); 
      OracleDate testdate2 = new OracleDate(newdate); 
     } 
    } 
}

testdate1被實例化就好了。

但是，testdate2會引發此錯誤。

[DllNotFoundException: Unable to load DLL 'OraOps11w.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)] 
    Oracle.DataAccess.Types.OpsDat.AllocValCtxFromData(Int32 year, Int32 month, Int32 day, Int32 hour, Int32 minute, Int32 second, OpoDatValCtx*& ctx) +0

    System.Web.UI.Control.LoadRecursive() +74 
    System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2207

如果真的找不到「OraOps11w.dll」，不會讓我在這兩種情況下的錯誤？我的DLL可能過時了嗎？

你可以嘗試升級到odp.net 11.2，並嘗試看看是否可行或驗證，你現在確實有與Xcopy的ODP.NET附帶的文件MSVCR71.DLL和mfc71.dll。 – 2012-02-27 20:38:30

我正在使用ODP.net 11.2。另外我有msvcr71，版本7.10.3052.4，mfc71.dll，版本7.10.3077.0。 – duckmike 2012-02-27 20:45:16

Unzip all the JAR's in zip file of odt.net you downloaded 
Get all the files inside that you just unzipped: 
    oci.dll (renamed from 'oci.dll.dbl') 
    Oracle.DataAccess.dll 
    oraociicus11.dll 
    OraOps11w.dll 
    orannzsbb11.dll 
    oraocci11.dll 
    ociw32.dll (renamed from 'ociw32.dll.dbl') 
Copy all the dll files into the bin dir of your .net exe

我將所有這些DLL複製到我的.exe文件夾中，但它仍然無法工作。 – duckmike 2012-02-27 20:54:02

嘗試從項目中刪除您的參考並再次添加。請嘗試將Oracle.DataAccess.dll放在與上述其他文件相同的bin目錄中。 – 2012-02-27 20:56:18

沒有。仍然不起作用。 – duckmike 2012-02-27 21:01:08
