如何实现图片的批量上传？
小弟现在在做一个类似于网上相册的东西，想实现用户一次选择多个图片后，然后一次上传到服务器段的文件夹中，我需要把每个文件的路径存到数据库中，请问这中该怎么实现呢？

后台代码：
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;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void bt_upload_Click(object sender, EventArgs e)
{
if ((FileUpload1.PostedFile.FileName == " " && FileUpload2.PostedFile.FileName == " ")&&FileUpload3.PostedFile.FileName == " ")
{
this.lb_info.Text = "请选择文件！ ";
}
else
{
HttpFileCollection myfiles = Request.Files;
for (int i = 0; i < myfiles.Count; i++)
{
HttpPostedFile mypost = myfiles[i];
try
{
if (mypost.ContentLength > 0)
{
string filepath = mypost.FileName;
string filename = filepath.Substring(filepath.LastIndexOf( "\\ ") + 1);
string serverpath = Server.MapPath( "images/ ") + filename;
mypost.SaveAs(serverpath);
this.lb_info.Text = "上传成功！ ";
}
}
catch (Exception error)
{
this.lb_info.Text = "上传发生错误！原因： " + error.ToString();
}
}
}
}
}
