本文介绍了一个使用ASP.NET实现文件上传的例子，包括图片和文档的上传，并通过XML文件来配置允许上传的文件类型。

xml 文件要求如下,下面代码必须手写.

<?xml version="1.0" encoding="utf-8" ?>
<fileset>
<upload></upload>
<fileformat>.jpg|.JPG|</fileformat>
<upload1>.doc|.html|.xls</upload1>
</fileset>

aspx页面

<form>

<table>

</table>

</form>

.aspx.cs页面

//引入空间

using System.IO;
using System.Xml;

//按钮buttron的点击事件

if (zhaopian.PostedFile.FileName != "")
{
XmlDocument document = new XmlDocument();

document.Load(Server.MapPath("UploadFile.xml"));

XmlNodeList cn = document.SelectNodes("fileset");//取图片

string strfileExt = cn.Item(0).SelectSingleNode("fileformat").InnerText.ToString();

                if (strfileExt.IndexOf(System.IO.Path.GetExtension(zhaopian.PostedFile.FileName)) == -1)
                {
                    Page.ClientScript.RegisterStartupScript(Page.GetType(), "", "<script language='javascript'>alert('只支持.jpg文件上传。');</script>");
                    return;
                }
                imgstrFileName = "picture" + "/" + System.DateTime.Now.Year.ToString() + System.DateTime.Now.Month.ToString() + System.DateTime.Now.Day.ToString() + System.DateTime.Now.Hour.ToString() + System.DateTime.Now.Minute.ToString() + System.DateTime.Now.Millisecond.ToString() + System.IO.Path.GetExtension(zhaopian.PostedFile.FileName);
                DirectoryInfo directoryinfo = new DirectoryInfo(Server.MapPath("picture"));
                if (!directoryinfo.Exists)
                {
                    directoryinfo.Create();
                }
                zhaopian.PostedFile.SaveAs(Server.MapPath(imgstrFileName));
            }
            if (gerenjianli.PostedFile.FileName != "")
            {
                //string jianlistrFileName = "";

XmlDocument document = new XmlDocument();

document.Load(Server.MapPath("UploadFile.xml"));

XmlNodeList cn = document.SelectNodes("fileset");//取简历

string strfileExt = cn.Item(0).SelectSingleNode("upload1").InnerText.ToString();

                {
                    Page.ClientScript.RegisterStartupScript(Page.GetType(), "", "<script language='javascript'>alert('只支持.doc.xls.html文件上传。');</script>");
                    return;
                }
                jianlistrFileName = "jianli" + "/" + System.DateTime.Now.Year.ToString() + System.DateTime.Now.Month.ToString() + System.DateTime.Now.Day.ToString() + System.DateTime.Now.Hour.ToString() + System.DateTime.Now.Minute.ToString() + System.DateTime.Now.Millisecond.ToString() + System.IO.Path.GetExtension(gerenjianli.PostedFile.FileName);

                {

                }
                zhaopian.PostedFile.SaveAs(Server.MapPath(jianlistrFileName));
            }
