.net中的FINDCONTROL和創建文件夾,保存文件

//GLOAL為自定義APPCODE類

查找PAGE的CONTROL

            HtmlForm form = (HtmlForm)this.Master.FindControl("form1");
            ContentPlaceHolder CP = (ContentPlaceHolder)form.FindControl("ContentPlaceHolder1");
            for (int i = 0; i < 4; i++)
            {
                string CName = "_fuFile" + Convert.ToString(i + 1);
                FileUpload FU = (FileUpload)CP.FindControl(CName);
                if (FU.HasFile)
                {
                    string FName = FU.FileName;
                    FU.PostedFile.SaveAs(Server.MapPath(Global.ApplicationPath + "/onlineprint_upload" + "/" + DateTime.Now.ToString("yyyyMMdd") + "/" + userid + "/" + FName));
                }
            }
查找用戶控件中的CONTROL 直接用THIS.FINDCONTROL

查找REPEATER中的，要對應ITEM[I].findcontrol

查找GRIDVIEW 要對應ROW[I].CELL[I].CONTROL[I];

另外 創建文件夾和保存文件

            string userid = Convert.ToString(Session["ComUserId"]);
            string dir = Server.MapPath(Global.ApplicationPath + "/onlineprint_upload" + "/" + DateTime.Now.ToString("yyyyMMdd") + "/" + userid);
          &

nbsp; System.IO.Directory.CreateDirectory(dir);
            HtmlForm form = (HtmlForm)this.Master.FindControl("form1");
            ContentPlaceHolder CP = (ContentPlaceHolder)form.FindControl("ContentPlaceHolder1");
            for (int i = 0; i < 4; i++)
            {
                string CName = "_fuFile" + Convert.ToString(i + 1);
                FileUpload FU = (FileUpload)CP.FindControl(CName);
                if (FU.HasFile)
                {
                    string FName = FU.FileName;
                    FU.PostedFile.SaveAs(Server.MapPath(Global.ApplicationPath + "/onlineprint_upload" + "/" + DateTime.Now.ToString("yyyyMMdd") + "/" + userid + "/" + FName));
                }
            }
