                            break;
                        }
                    case ".gif":
                        {
                            HttpContext.Current.Response.ContentType = "image/gif";
                            HttpContext.Current.Response.AppendHeader("Content-disposition", "inline;filename=" + Path.GetFileName(filepath));
                            break;
                        }
                    case ".png":
                        {
                            HttpContext.Current.Response.ContentType = "image/png";
                            HttpContext.Current.Response.AppendHeader("Content-disposition", "inline;filename=" + Path.GetFileName(filepath));
                            break;
                        }
                    default:
                        {
                            HttpContext.Current.Response.ContentType = "application/octet-stream";
                            HttpContext.Current.Response.AppendHeader("content-disposition", "attachment;filename=" + Path.GetFileName(filepath));
                            break;
                        }
                }
                //HttpContext.Current.Response.ContentType = "application/octet-stream";
                //HttpContext.Current.Response.AppendHeader("content-disposition", "attachment; filename=" + Path.GetFileName(fileFullPath));                               
                //var pageTitle = (Page)HttpContext.Current.Handler;                
                //pageTitle.Title=Path.GetFileName(fileFullPath);
                HttpContext.Current.Response.End();
                viewname = "TicketUpdateDetailView";
            }
            catch (System.Threading.ThreadAbortException ex1)
            {

            }
            catch (Exception ex)
            {

            }
            return viewname;
        }

如果我的代码有任何问题，请纠正我....


预先感谢

推荐答案

根据您的条件，浏览器选项卡的标题将仅是图像的名称.尝试检查图像文件的名称.
如果要动态生成任何HTML页面，然后尝试在该页面中显示图像，则必须在这种情况下设置Title.

As per your condition, the title of the browser tab will be the name of the image only. Try checking the name of your image file.
If you are generating any HTML page dynamically and then trying to display the image in that page, you''ll have to set the Title in that case.
