C#文件上傳

 //var fileName = System.IO.Path.GetFileName(upload.FileName);
            //var filePhysicalPath = Server.MapPath("~/Content/" + fileName);//我把它保存在網站根目錄的 upload 文件夾

            return Content("<script>window.parent.CKEDITOR.tools.callFunction(" + CKEditorFuncNum + ", \"" + url + "\");</script>");
      

 

 string fileExt = postFile.FileName.Substring(postFile.FileName.LastIndexOf(".") + 1); //文件擴展名，不含“.”
                    string newFileName = DateTime.Now.ToString("yyyyMMddHHmmssffff") + "." + fileExt; //隨機生成新的文件名
