解決之道（注意紅字部分）：

SPSite mySeite = null;
                SPWeb myWeb = null;
                try
                {
                    mySeite = new SPSite(_siteUrl);
                    myWeb = mySeite.OpenWeb();
                    SPList myList = myWeb.Lists[new Guid(this._ms.ListID)];
                   
                    //Guid = new Guid();                  
                    SPListItem spfolder = myList.Folders[new Guid(this._ms.FolderID)];
                    SPFolder spfolderA = spfolder.Folder;

                    myWeb.AllowUnsafeUpdates = true;//該代碼錶示允許代碼更新
                    spfolderA.Item["是否發送"] = true;
                    //spfolder["是否發送"] = true;
                    spfolderA.Item.Update();
                    spfolderA.Update();
                }
                catch (Exception EailException)
                {
                    F_MailSend("softadmin@delta.com.cn", "cheng.cheng@delta.com.cn", "EailException", "" + EailException.Message + "<br>" + EailException.StackTrace+" <br> line 1278");
                }
                finally
                {
                    if (mySeite != null)
                    {
                        mySeite.Dispose();
                    }
                    if (myWeb != null)
                    {
                        myWeb.Dispose();
                    }
