另存为提示“图像名称"在通用handler.ashx中? [英] Save As prompt "image name" in generic handler.ashx ?

问题描述

当我使用Handler.ashx ans从文件夹中显示图像时，尝试通过右键单击来保存图像，它始终为我提供另存为类型"选项，即asp.net通用处理程序，并将处理程序名称作为文件名..

When i am displaying image from folder using Handler.ashx ans then try to save the image by right clicking it it keeps giving me the option of "Save as type" asp.net generic handler and the handler name as the File name..

Bitmap target = new Bitmap(width, height);
    using (Graphics graphics = Graphics.FromImage(target)) {
        graphics.CompositingQuality = CompositingQuality.HighSpeed;
        graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
        graphics.CompositingMode = CompositingMode.SourceCopy;
        graphics.DrawImage(photo, 0, 0, width, height);
        using (MemoryStream memoryStream = new MemoryStream()) {
            target.Save(memoryStream, ImageFormat.Png);
            OutputCacheResponse(context, File.GetLastWriteTime(photoPath));
            using (FileStream diskCacheStream = new FileStream(cachePath, FileMode.CreateNew))
            {
                memoryStream.WriteTo(diskCacheStream);
            }
            memoryStream.WriteTo(context.Response.OutputStream);
        }
    }

上面是处理程序，而

ImageTiff.ImageUrl = "Handler.ashx?p=" + Parameter; 

这是背后的代码.

我需要将其保存为图像名称ans而不是handler.ashx

I need to save it with the Image name ans not as the handler.ashx

推荐答案

          context.Response.ContentType = "image/pjpeg"; 
          context.Response.AddHeader("Content-Disposition", "attachment; filename=\"" + photoName  + "\"");

          OutputCacheResponse(context, File.GetLastWriteTime(photoPath));

           context.Response.Flush();


           using (FileStream diskCacheStream = new FileStream(cachePath, FileMode.CreateNew))
           {
               memoryStream.WriteTo(diskCacheStream);
           }
            memoryStream.WriteTo(context.Response.OutputStream);
