最近工作比较忙,好长时间都没有到我的博客里来看看了。前天帮我兄弟解决了一个多文件上传的问题。供大家参考 前台代码如下 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="upMoreFile.aspx.cs" Inherits="upMoreFile" %><!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 runat="server"> <title>上传多文件</title> <script type="text/javascript"> function addFileControl() ...{ var str = '<INPUT type="file" NAME="File">' document.getElementById('FileCollection').insertAdjacentHTML("beforeEnd",str) } </script></head><body> <form id="upmorefile" runat="server" method="post" enctype="multipart/form-data"> <div> <asp:label id="Title" Runat="server"></asp:label> <p id="FileCollection"><input type="file" name="File"/> </p> <p><input onclick="addFileControl()" type="button" value="增加(File)"/> <asp:button id="Upload" Runat="server" Text="上传" Width="56px" OnClick="Upload_Click"></asp:button><input style="WIDTH: 56px; HEIGHT: 24px" onclick="this.form.reset()" type="button" value="重置"/> </p> <p align="center"><asp:label id="strStatus" runat="server" BorderColor="White" BorderStyle="None" Width="500px" Font-Size="9pt" Font-Bold="True" Font-Names="宋体"></asp:label></p> </div> </form></body></html> .cs代码如下: 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 upMoreFile : System.Web.UI.Page...{ protected void Page_Load(object sender, EventArgs e) ...{ Title.Text = "<h3>多文件上传</h3>"; Upload.Text = "开始上传"; } /**//// <summary> /// 方法名:upMoreFile() /// 功能描述:循环表单,多文件上传 /// 调用方法:bool var=upMoreFile() /// </summary> /// <returns>bool</returns> protected bool upMorefile() ...{ //遍历File表单元素 System.Web.HttpFileCollection files = System.Web.HttpContext.Current.Request.Files; //状态信息 System.Text.StringBuilder strMsg = new System.Text.StringBuilder("上传的文件信息分别为:<hr color=red>"); int fileCount; int filecount = files.Count; try ...{ for (fileCount = 0; fileCount < files.Count; fileCount++) ...{ //定义访问客户端上传文件的对象 System.Web.HttpPostedFile postedFile = files[fileCount]; string fileName, fileExtension; //取得上传得文件名 fileName = System.IO.Path.GetFileName(postedFile.FileName); if (fileName != String.Empty) ...{ //取得文件的扩展名 fileExtension = System.IO.Path.GetExtension(fileName); //上传的文件信息 strMsg.Append("上传的文件类型:" + postedFile.ContentType.ToString() + "<br>"); strMsg.Append("客户端文件地址:" + postedFile.FileName + "<br>"); strMsg.Append("上传文件的文件名:" + fileName + "<br>"); strMsg.Append("上传文件的扩展名:" + fileExtension + "<br><hr color=red>"); //保存到指定的文件夹 postedFile.SaveAs(Server.MapPath("upedFile/") + fileName); } } strStatus.Text = strMsg.ToString(); return true; } catch (System.Exception error) ...{ strStatus.Text = error.Message; return false; } } protected void Upload_Click(object sender, EventArgs e) ...{ upMorefile(); }} 效果如下:
