对于Uploadify文件上传之前已经讲过一次(文件上传~Uploadify上传控件),只不过没有涉及到多文件的上传,这回主要说一下多个文件的上传,首先,我们要清楚一个概念,多文件上传前端Uploadify是通过轮训的方式去调用我们的后台upload程序的,所以,对于多文件上传来说,也没什么稀奇的.

 public class UploadHandler : IHttpHandler
 {

 public void ProcessRequest(HttpContext context)
 {
  context.Response.ContentType = "text/plain";
  context.Response.Charset = "utf-8";

  HttpPostedFile file = context.Request.Files["Filedata"];
  string uploadPath = HttpContext.Current.Server.MapPath(@context.Request["folder"]);

  if (file != null)
  {
  if (!Directory.Exists(uploadPath))
  {
   Directory.CreateDirectory(uploadPath);
  }

  file.SaveAs(Path.Combine(uploadPath, file.FileName));

  var pathArr = uploadPath.Split('\\');

  context.Response.Write(HttpContext.Current.Request.Url.Scheme
   + "://"
   + HttpContext.Current.Request.Url.Authority
   + "/"
   + pathArr[pathArr.Length - 2]
   + "/"
   + pathArr[pathArr.Length - 1]
   + "/"
   + file.FileName);
  }
  else
  {
  context.Response.Write("0");
  }
 }
