我有一个存储一些文件的SQL数据库.
用户可以登录该应用程序,并查看其文档列表.
当在文档的gridview中单击链接按钮下载时,我从数据库中获取文件,将其写入文件系统,然后执行此代码.
System.IO.FileInfo file = new System.IO.FileInfo(System.Configuration.ConfigurationManager.AppSettings["UploadPath"] + DocumentName); Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); Response.Cookies.Clear(); Response.Cache.SetCacheability(HttpCacheability.Private); Response.CacheControl = "private"; Response.Charset = System.Text.UTF8Encoding.UTF8.WebName; Response.ContentEncoding = System.Text.UTF8Encoding.UTF8; Response.AppendHeader("Content-Length", file.Length.ToString()); Response.AppendHeader("Pragma","cache"); Response.AppendHeader("Expires", "60"); Response.ContentType = GetContentType(file.Extension); Response.AppendHeader("Content-Disposition", "inline; " + "filename=\"" + file.Name + "\"; " + "size=" + file.Length.ToString() + "; " + "creation-date=" + DateTime.Now.ToString("R") + "; " + "modification-date=" + DateTime.Now.ToString("R") + "; " + "read-date=" + DateTime.Now.ToString("R"));
我的GetContentType()方法只返回我允许的文件的相应文件类型"application/pdf,application/msw0rd等.
我的问题是,当文件被保存时,它是网页本身,而不是文件系统中的文件.在谷歌浏览器中,它在文件名的末尾添加.htm扩展名,我猜是因为它知道它是一个网页?
无论如何,一个伟大的第一步是获取实际文件,而不是他们所坐的HTML网页的副本!
谢谢.
代替
Response.AppendHeader("Content-Disposition","inline;"+"filename =
使用
Response.AddHeader("content-disposition:","attachment; filename =
你是如何发送文件的实际内容的?
我通常使用Response.TransmitFile方法,它基本上打开文件并将其内容发送到Response.OutputStream
