极度崩溃，关于jquery中uploadify批量上传的问题，哪位达人救救我吧。

本人要用jquery做批量上传，一个upload.aspx用于存放uploadify控件，一个UploadHandler.ashx用于保存图片，同时写入数据库。
  现在有个实在很无解的问题，有时候图片能上传成功，有时候却上传不成功，也没有提示，试了就算只上传一个也有不成功的，而且就算成功了也是有时候能执行oncompelete，有时后不执行，现在代码贴出来给大家看看到底有什么问题。。在线等大家回答。
先是upload.aspx的html：
<%@ Page Language="C#" Debug="True" AutoEventWireup="true" CodeFile="upload.aspx.cs" Inherits="upload" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

然后是upload.aspx.cs文件:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using System.IO;

public partial class upload : System.Web.UI.Page
{

  protected void Page_Load(object sender, EventArgs e)
  { int flag=0;// int type=1;

  document.Text =Request.QueryString["documentno"].ToString();
  // btnUpload.Attributes.Add("onclick", "return iscorrect()");
  ddlAlbum.Text = Session["usercode"].ToString().Substring(0, 8);
  if (document.Text.Substring(0, 1) == "P") {
  note.Text = "承保"; flag = 1;

  }
  else if (document.Text.Substring(0, 1) == "A") { note.Text = "理赔"; flag = 3; }
  else {
  note.Text = "防灾防损"; flag = 2;
  }

  string insertstr = "";
  insertstr = document.Text;
  Session["insertstr"] = insertstr;
  string script = "$('#uploadify').uploadifyUpload()";
  // Response.Write("<script>alert('" + Session["insertstr"] .ToString()+ "')</script>");
  btnUpload.Attributes.Add("onclick", script);
  }

最后是UploadHandler.ashx：
<%@ WebHandler Language="C#" Class="UploadHandler" %>

using System;
using System.IO;
using System.Net;
using System.Web;
using System.Data.Sql;
using System.Data.SqlTypes;
using System.Data.Common;
using System.Data.SqlClient;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public class UploadHandler : IHttpHandler, System.Web.SessionState.IRequiresSessionState{

  public void ProcessRequest(HttpContext context) {
  int flag=0;
  int type=0;
  // HttpContext context=HttpContext.Current;
  try
  {
  context.Response.ContentType = "text/plain";
  context.Response.ContentEncoding = System.Text.Encoding.UTF8;
  context.Request.ContentEncoding = System.Text.Encoding.UTF8;
  if (context.Session["insertstr"] != null)
  {

  string PicPath = "";
  string comcode =context.Session["usercode"].ToString().Substring(0,8);

  string documentno = context.Session["insertstr"].ToString();
  if (documentno.Substring(0, 1) == "P")
  {
  flag = 1;

  }
  else if (documentno.Substring(0, 1) == "A") { flag = 3; }
  else
  {
  flag = 2;
  }
  string dirname = comcode+documentno;
  string dirpath =context.Server.MapPath("./PicBase");
  dirpath = dirpath + "\\" + dirname;
  dirpath = dirpath + DateTime.Now.ToString("yyyy-MM-dd");
  if (Directory.Exists(dirpath) == false)
  {
  Directory.CreateDirectory(dirpath);
  }
  Random ro = new Random();
  int name = 100;

  for (int i = 0; i < context.Request.Files.Count; i++)
  {
  name = name + i;
  string FileExtention = "";
  string date = DateTime.Now.ToString("yyyy-MM-dd-HH");
  HttpPostedFile myFile = context.Request.Files[i];
  string FileName = Path.GetFileName(myFile.FileName);
  string NewName = "";
  if (FileName != "")
  {
  FileExtention = Path.GetExtension(myFile.FileName);
  // postedFile.SaveAs(fileName);
  if (FileExtention != ".doc" && FileExtention != ".DOC")
  {
  type = 1;
  string stro = comcode+FileName.Substring(FileName.IndexOf("\\") + 1, FileName.IndexOf(FileExtention))+date + name.ToString(); NewName = stro;
  }
  else
  {
  type = 2;
  NewName = comcode + FileName.Substring(FileName.IndexOf("\\") + 1, FileName.IndexOf(FileExtention)) + DateTime.Now.ToString("yyyy-MM-dd-HH")+name.ToString();
  // Response.Write("<script>alert('"+NewName+" ')</script>");
  }
  string ppath = dirpath + "\\" + NewName + FileExtention;
  myFile.SaveAs(ppath);
  // myFile.SaveAs(ppath);
  string FJname = FileName;
  PicPath = "PicBase" + "\\" + dirname + DateTime.Now.ToString("yyyy-MM-dd") + "\\" + NewName + FileExtention;
  //TextBox1.Text = PicPath.ToString();
  Console.WriteLine(FileName);
  AddPicture(PicPath, FileName.Substring(FileName.IndexOf("\\") + 1, FileName.IndexOf(FileExtention)), comcode, DateTime.Now, documentno, flag, type);//将图片
  }
  }
  }
  context.Response.Write("");
  }
  catch (Exception ex)
  {
  context.Response.ContentType = "text/plain";
  context.Response.Write(ex.Message);
  }
  }
  private void AddPicture(string imgpath, string imgnote, string albumid, DateTime time, string documentno,int flag,int type)
  {

  string sql = "insert WB_AlbumImges(ImgPath,ImgNote,AlbumID,time,documentno,flag,type) values('" + imgpath + "','" + imgnote + "','" + albumid + "','" + time + "','" + documentno + "','" + flag + "','" + type + "')";
  string ads = "Data Source=40.177.31.253;Initial Catalog=piccimage;User ID=sa;Password=abc123;";
  SqlConnection mydb = new SqlConnection(ads);
  SqlCommand cmd = new SqlCommand(sql);
  mydb.Open();
  cmd.Connection = mydb;
  cmd.ExecuteNonQuery();

  mydb.Close();

  }



  public bool IsReusable {
  get {
  return false;
  }
  }


}
大家救救我吧。

百度搜索，应该是upload的文件最大上传限制，不过即使增加了文件上传大小容量，效果也不好，还会刷新页面。
解决思路：去网上下载NeatUpload组件，下载后的文件（或者解压后）是一套组件，有DLL和JS等文件，直接用到项目中，改一改webconfig就行。这个组件无刷新，最大容量和强，因为服务器关系，我在项目中只测试了一个G的文件上传，文件上传没有页面刷新，而且带有进度条，上传样式可以改其中的CSS文件，具体动作修改其中的JS文件，组件下载后的文件中有详细的说明。
