Question

所以我的代码看起来像 -

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实例化得很好。

但是，testdate2会抛出此错误。

[DllNotFoundException: Unable to load DLL 'OraOps11w.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)]

如果它真的找不到'OraOps11w.dll'，我不会在两个实例上都出错吗？我的dll可能已经过时了吗？

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

实例化OracleDate对象
