C#使用file无法修改netware操作系统下的文件创建日期

因某些原因需要更改Netware网络操作系统下的文件创建时间，但只能更改最近修改时间，文件创建时间修改不成功。

相同代码在更改Windows服务器的文件时可以更改成功。

代码如下：

        public  void RefreshFilterFilesDate(string strFilter, string strPath, int iYear, int iMonth, int iDay, int iHour, int iMinute)
        {

            int deYear, deMonth, deDay, deHour, deMinute;
            bool isExist = System.IO.Directory.Exists(strPath);
            if (isExist)
            {
                deYear = iYear;
                deMinute = iMonth;
                deDay = iDay;
                deHour = iHour;
                deMinute = iMinute;
                string[] myTxtFiles = Directory.GetFiles(strPath, strFilter, SearchOption.AllDirectories);
                foreach (string myTxtFile in myTxtFiles)
                {                    
                    DateTime dateModified;
                    DateTime oldDate, newDate;
                    myNCFile = myTxtFile;
                    oldDate = File.GetCreationTime(myTxtFile);
                    dateModified =File.GetLastWriteTime(myTxtFile);
                    
                    if (oldDate.CompareTo(dateModified) < 0)
                    {
                        oldDate = dateModified;
                    }

                    deYear = iYear == 0 ? 2002 : iYear;
                    deMonth = iMonth == 0 ? oldDate.Month : iMonth;
                    deDay = iDay == 0 ? oldDate.Day : iDay;\\问题出在这里,月份为2，日期〉28时出错
                    deHour = iHour == 0 ? oldDate.Hour : iHour;
                    deMinute = iMinute == 0 ? oldDate.Minute : iMinute;
                    newDate = new DateTime(deYear, deMonth, deDay, deHour, deMinute, oldDate.Second,oldDate.Millisecond);
                    TimeSpan ts = newDate.Subtract(oldDate);
                    
                    if (newDate != oldDate)
                    {
                        File.SetCreationTime(myTxtFile, newDate);
                        File.SetLastWriteTime(myTxtFile, newDate);

                        myNCFile = myNCFile + "\t" + oldDate + "\t" + newDate;
                        InvokeDoWith mi = new InvokeDoWith(AddLVItem);
                        this.Invoke(mi); 
                    }
                }
            }
        } 

 

您有什么方法实现吗？
