Firefox 下载文件名被截断

Question

Path = IO.Path.Combine(Path, FileName)
            myFileInfo = New FileInfo(Path)
            FileSize = myFileInfo.Length
            EndPos = FileSize
            HttpContext.Current.Response.Clear()
            HttpContext.Current.Response.ContentType = SWGeneral.GetContentType(FileName)
            HttpContext.Current.Response.AddHeader("Content-disposition", "attachment; filename=" & myFileInfo.Name)
            HttpContext.Current.Response.WriteFile(Path, StartPos, EndPos)
            HttpContext.Current.Response.End()例如我的文件名称是 111 222 333.rar 那么在Firefox下载的时候是 111 被空格截断了.请问朋友们如何解决这个问题.

Answer 1

Response.AddHeader("content-disposition", "attachment;filename=" + HttpUtility.UrlEncode((myFileInfo.Name), System.Text.Encoding.UTF8));

Answer 2

您好,朋友这个方式我用过,在Firefox在空格会转换成 "+" 号 最终显示结果是 111+222+333.rar请问还有别的方法吗?我想让他显示111 222 333.rar

Answer 3

string UserAgent = Request.ServerVariables["http_user_agent"].ToLower(); 
string FileName = ""; 
if(UserAgent.IndexOf("firefox") == -1) 
    FileName = HttpUtility.UrlEncode(FileName, Encoding.UTF8); 
Response.AppendHeader("content-type", "application/octet-stream"); 
Response.AppendHeader("Content-Disposition", "attachment;filename="+FileName); 
Response.WriteFile(DownloadFile.FullName); 
Response.Flush(); 
Response.End();
