这篇文章主要介绍C#如何实现文件上传与下载,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
C#实现文件上传代码:
public ActionResult Upload() { // var pathUrl = "http://" + Request.Url.Authority; var file = Request.Files["Filedata"]; var uploadFileName = file.FileName; string filePath = "/File/" + uploadFileName; string AbsolutePath = Server.MapPath(filePath); file.SaveAs(AbsolutePath); //将上传的东西保存 return Json(new { FileName = uploadFileName, FilePath = filePath }); }
C#实现文件下载功能:
public ActionResult DownLoad(string FileName) { string fileName = FileName;//客户端保存的文件名 string filePath = Server.MapPath("/File/"+ FileName);//路径 //以字符流的形式下载文件 FileStream fs = new FileStream(filePath, FileMode.Open); byte[] bytes = new byte[(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(); return Json(""); }
