需要下载NeatUpload插件
上传页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="index.aspx.cs" Inherits="_Default" %> <%@ Register Assembly="Brettle.Web.NeatUpload" Namespace="Brettle.Web.NeatUpload" TagPrefix="Upload" %> <!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></title> <link href="easyui/themes/default/easyui.css" rel="stylesheet" type="text/css" /> <link href="easyui/themes/icon.css" rel="stylesheet" type="text/css" /> <script src="easyui/jquery.min.js" type="text/javascript"></script> <script src="easyui/jquery.easyui.min.js" type="text/javascript"></script> </head> <body> <form id="form1" runat="server"> <div> <Upload:ProgressBar ID="ProgressBar1" runat='server'> </Upload:ProgressBar> <br /> <Upload:InputFile ID="AttachFile" runat="server" /> <br /> <br /> <asp:LinkButton ID="BtnUP" runat="server" data-options="iconCls:'icon-add'">上 传</asp:LinkButton><br /><br /> <a href="Down.aspx">查看下载</a> </div> </form> </body> </html>
后台源码：
protected void BtnUP_Click(object sender, EventArgs e) { if (AttachFile.HasFile) { string FileName = this.AttachFile.FileName;//获取上传文件的文件名,包括后缀 string ExtenName = System.IO.Path.GetExtension(FileName);//获取扩展名 string SaveFileName = System.IO.Path.Combine(System.Web.HttpContext.Current.Request.MapPath("UpLoads/"), DateTime.Now.ToLongDateString().ToString() + "-" + FileName);//合并两个路径为上传到服务器上的全路径 AttachFile.MoveTo(SaveFileName, Brettle.Web.NeatUpload.MoveToOptions.Overwrite); string url = "UpLoads/" + DateTime.Now.ToString("yyyyMMddhhmmss") + ExtenName; //文件保存的路径 float FileSize = (float)System.Math.Round((float)AttachFile.ContentLength / 1024000, 1); //获取文件大小并保留小数点后一位,单位是M Response.Write("<script>alert('恭喜您，上传成功!')</script>"); } else { Response.Write("<script>alert('请选择文件！')</script>"); } }
这里直接获取上传文件夹文件名称提供下载
