.net 文件下载功能的实现

下载功能，在点击事件里面添加如下代码，即可实现文件下载功能

try
        {
            string strFilePath = Server.MapPath("~") + "/files/0.jpg";//服务器文件路径
            FileInfo fileInfo = new FileInfo(strFilePath);
            Response.Clear();
            Response.Charset = "GB2312";
            Response.ContentEncoding = System.Text.Encoding.UTF8;
            Response.AddHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(fileInfo.Name));
            Response.AddHeader("Content-Length", fileInfo.Length.ToString());
            Response.ContentType = "application/x-bittorrent";
            Response.WriteFile(fileInfo.FullName);
            Response.End();
        }
        catch (System.Threading.ThreadAbortException ex)
        {
            //不做处理
        }
        catch (Exception ex)
        {
            //做处理
        }

其中strFilePath为服务器文件路径
