“废话不多说,直接给家长代码了,具体代码如下:
csharppublic ActionResult Upload(){ // var pathUrl=http://; var file=Request.Files[Filedata]; var uploadFileName=file.FileName; // stri}
废话不多说了,直接给大家贴代码了,具体代码如下所示:
public ActionResult Upload() { // var pathUrl = "" + 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 }); }
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(""); }
总结
以上所述是小编给大家介绍的C#实现文件上传及文件下载功能实例代码,希望对大家有所帮助,如果大家有任何疑问请给我留言,小编会及时回复大家的。在此也非常感谢大家对易盾网络网站的支持!
