C#实现文件上传代码:
publicActionResult Upload() { // var pathUrl = "http://" + Request.Url.Authority; var file = Request.Files["Filedata"]; var uploadFileName = file.FileName; stringfilePath ="/File/"+ uploadFileName; stringAbsolutePath = Server.MapPath(filePath); file.SaveAs(AbsolutePath); //将上传的东西保存 returnJson(new{ FileName = uploadFileName, FilePath = filePath }); }
C#实现文件下载功能:
publicActionResult DownLoad(stringFileName) { stringfileName = FileName;//客户端保存的文件名 stringfilePath = Server.MapPath("/File/"+ FileName);//路径 //以字符流的形式下载文件 FileStream fs =newFileStream(filePath, FileMode.Open); byte[] bytes =newbyte[(int)fs.Length]; fs.Read(bytes, 0, bytes.Length); fs.Close(); Response.ContentType ="application/octet-stream"; //通知浏览器下载文件而不是打开 Response.AddHeader("Content-Disposition","attachment; filename="+ HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8)); Response.BinaryWrite(bytes); Response.Flush(); Response.End(); returnJson(""); }
