خطای دسترسی به فولدر موقع ذخیره سازی

[MasoudAdmin]

با سلام
من یک کد نوشتم که فایل Word رو از دیتابیس بخونه و بعد پارامترها رو Replace کنه و در فولدر MyDocument ویندوز ذخیره کنه. ولی موقع ذخیره شدن در فولدری که اعلام کردم خطای دسترسی میده. با اینکه دسترسی Full Control هم به فولدر دادم بازم خطا میده. حتی فولدر دستی تو درایو دیگه هم تعریف کردم و دسترسی Full Control هم دادم ولی باز هم همون خطا رو داره.

mydocumentsPath= Environment.GetFolderPath(Environment.SpecialFolde  r.MyDocuments) + "\\Guarantee";

if (!System.IO.Directory.Exists(mydocumentsPath))

                {

                    System.IO.Directory.CreateDirectory(mydocumentsPat  h);

                    Random myrandom = new Random();

                    int MyValue = myrandom.Next();

                    string sFileName = mydocumentsPath + "\\tmp" + MyValue.ToString().Trim() + Extention;

                    byte[] filebyte;

                    CmdMain.CommandText = "Select LetterBody From VW_LetterSubject Where LetterCode=" + LetterCode;

                    filebyte = (byte[])CmdMain.ExecuteScalar();

                    string sTempFileName = Application.StartupPath + sFileName;

                    FileStream FS = new FileStream(sFileName, FileMode.OpenOrCreate, FileAccess.Write);

                    FS.Write(filebyte, 0, filebyte.Length);

                    FS.Flush();

                    FS.Close();

                    Document document = new Document();

                    document.LoadFromFile(sFileName);

                    Dictionary<string, string> dictReplace = GetReplaceDictionary();

                    //Replace text  

                    foreach (KeyValuePair<string, string> kvp in dictReplace)

                    {

                        document.Replace(kvp.Key, kvp.Value, true, true);

                    }

                    //Save doc file.  

                    document.SaveToFile(mydocumentsPath, FileFormat.Docx);

                    document.Close();

                    ConData.Close();

                }

                else

                {

                    foreach (string strFiles in System.IO.Directory.GetFiles(mydocumentsPath))

                    {

                        System.IO.File.Delete(strFiles);

                    }

                    Random myrandom = new Random();

                    int MyValue = myrandom.Next();

                    string sFileName = mydocumentsPath + "\\tmp" + MyValue.ToString().Trim() + Extention;

                    byte[] filebyte;

                    FileStream FS = new FileStream(sFileName, FileMode.OpenOrCreate, FileAccess.Write);

                    FS.Write(filebyte, 0, filebyte.Length);

                    FS.Flush();

                    FS.Close();

                    Document document = new Document();

                    document.LoadFromFile(sFileName);

                    Dictionary<string, string> dictReplace = GetReplaceDictionary();

                    //Replace text  

                    foreach (KeyValuePair<string, string> kvp in dictReplace)

                    {

                        document.Replace(kvp.Key, kvp.Value, true, true);

                    }

                    //Save doc file.  

                    document.SaveToFile(mydocumentsPath, FileFormat.Docx);

                    document.Close();

                    ConData.Close();

                }

فقط یک مشکلی داره وقتی فایل ورد رو باز میکنه تاریخ رو برعکس جایگزین میکنه. با اینکه تو کد گفتم راست چین باشه ولی باز برعکس تاریخ رو نمایش میده.
تاریخ رو تو فایل ورد که جایگزین میکنه اینجوری هست: 15/07/1400
چجوری می تونم اینو حلش کنم؟
