<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> <form action="exec/Upload.ashx" enctype="multipart/form-data" method="post"> <input name="file" type="file" /> <input type="submit" value="提交" /> </form> </body> </html>

页面1里面写这些

<%@ WebHandler Language="C#" Class="Upload" %> using System; using System.Web; public class Upload : IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "text/plain"; HttpFileCollection imgs = context.Request.Files; if (imgs.Count>0) { for (int i = 0; i < imgs.Count; i++) { if (imgs[i].ContentLength!=0) { string oldName=imgs[i].FileName.ToString(); string imgName = Guid.NewGuid().ToString(); string imgType = oldName.ToString().Substring(oldName.LastIndexOf(".")); string imgPath = "~/upload/" + imgName + imgType; imgs[i].SaveAs(context.Server.MapPath(imgPath)); } } } } public bool IsReusable { get { return false; } } }
