asp上传文件代码下载
❶ asp.net 2.0中如何实现上传文件与下载文件 用啥控件和代码啊
需用到FileUpLoad控件
#region 文件上传
/*
if (FileUpload1.HasFile)
{
string type = FileUpload1.PostedFile.ContentType.ToString();
if (type == "image/pjpeg")
{
string path = Server.MapPath("up/");
FileUpload1.PostedFile.SaveAs(path + FileUpload1.FileName);
Response.Write("<script>alert('上传成功！');</script>");
}
else
Response.Write("<script>alert('请上传获得支持的文件类型！');</script>");
}
else
Response.Write("<script>alert('请选择您要上传的文件！');</script>");
//*/
❷ asp关于文件的上传和下载功能
先说明一下：
一、组件上传，在使用方法上，使用代码少，更安全，更容易控制，并且功能更强大，比如可以实现控制上传图片的尺寸，可以实现真实的上传进度条等，并且上传图片后可以进行对图片进行编辑等。但缺点是要求服务必需安装这个组件，如果是自己的服务器还好办，如果你是租用空间的话，那么最好放弃组件上传吧。
二、无组件上传，在使用上相对稍复杂一点，需要你到网上下载一个“ASP无组件上传类”(一般为一个.inc文件)，不能对图片进行处理，只可以控制上传的文件类型，文件大小等，优点是对服务器无要求，租用的服务器空间绝大多数都可以使用。
综上所述，对于一般小站或企业网站，上传文件不多，文件不大，要求不高的都使用无组件上传。
目前较流行的 无组件上传类有：
化境ASP无组件上传类
风声ASP无组件上传类
艾恩ASP无组件上传类
等，你在网络里搜索以上关键字，找到官方网站，可以免费下载相关上传类，并且有详细用法说明，及例子。

❹ 求ASP.NET WEB项目文件夹上传下载解决方案
ASP.NET上传文件用FileUpLoad就可以，但是对文件夹的操作却不能用FileUpLoad来实现。
下面这个示例便是使用ASP.NET来实现上传文件夹并对文件夹进行压缩以及解压。
ASP.NET页面设计：TextBox和Button按钮。
TextBox中需要自己受到输入文件夹的路径（包含文件夹），通过Button实现选择文件夹的问题还没有解决，暂时只能手动输入。
两种方法：生成rar和zip。
1.生成rar
using Microsoft.Win32;
using System.Diagnostics;
protected void Button1Click(object sender, EventArgs e)
{
RAR(@"E：95413594531GIS", "tmptest", @"E：95413594531");
}
///
///压缩文件
///
///需要压缩的文件夹或者单个文件
///生成压缩文件的文件名
///生成压缩文件保存路径
///
protected bool RAR(string DFilePath, string DRARName,string DRARPath)
{
String therar;
RegistryKey theReg;
Object theObj;
String theInfo;
ProcessStartInfo theStartInfo;
Process theProcess;
try
{
theReg = Registry.ClassesRoot.OpenSubKey(@"ApplicationsWinRAR.exeShellOpenCommand"); //注：未在注册表的根路径找到此路径
theObj = theReg.GetValue("");
therar = theObj.ToString();
theReg.Close();
therar = therar.Substring(1, therar.Length - 7);
theInfo = " a" + " " + DRARName + "" + DFilePath +" -ep1"; //命令 + 压缩后文件名 + 被压缩的文件或者路径
theStartInfo = new ProcessStartInfo();
theStartInfo.FileName = therar;
theStartInfo.Arguments = theInfo;
theStartInfo.WindowStyle = ProcessWindowStyle.Hidden;
theStartInfo.WorkingDirectory = DRARPath ; //RaR文件的存放目录。
theProcess = new Process();
theProcess.StartInfo = theStartInfo;
theProcess.Start();
theProcess.WaitForExit();
theProcess.Close();
return true;
}
catch (Exception ex)
{
return false;
}
}
///
///解压缩到指定文件夹
///
///压缩文件存在的目录
///压缩文件名称
///解压到文件夹
///
protected bool UnRAR(string RARFilePath,string RARFileName,string UnRARFilePath)
{
//解压缩
String therar;
RegistryKey theReg;
Object theObj;
String theInfo;
ProcessStartInfo theStartInfo;
Process theProcess;
try
{
theReg = Registry.ClassesRoot.OpenSubKey(@"ApplicationsWinRar.exeShellOpenCommand");
theObj = theReg.GetValue("");
therar = theObj.ToString();
theReg.Close();
therar = therar.Substring(1, therar.Length - 7);
theInfo = @" X " + " " + RARFilePath + RARFileName + " " + UnRARFilePath;
theStartInfo = new ProcessStartInfo();
theStartInfo.FileName = therar;
theStartInfo.Arguments = theInfo;
theStartInfo.WindowStyle = ProcessWindowStyle.Hidden;
theProcess = new Process();
theProcess.StartInfo = theStartInfo;
theProcess.Start();
return true;
}
catch (Exception ex)
{
return false;
}
}
注：这种方法在在电脑注册表中未找到应有的路径，未实现，仅供参考。
2.生成zip

以上这两个类库可以直接在程序里新建类库，然后复制粘贴，直接调用即可。
主程序代码如下所示：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Drawing;
using Microsoft.Win32;
using System.Diagnostics;
namespace UpLoad
{
public partial class UpLoadForm : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
if (TextBox1.Text == "") //如果输入为空,则弹出提示
{
this.Response.Write("<script>alert('输入为空，请重新输入！');window.opener.location.href=window.opener.location.href;</script>");
}
else
{
//压缩文件夹
string zipPath = TextBox1.Text.Trim(); //获取将要压缩的路径(包括文件夹)
string zipedPath = @"c: emp"; //压缩文件夹的路径(包括文件夹)
Zip Zc = new Zip();
Zc.ZipDir(zipPath, zipedPath, 6);
this.Response.Write("<script>alert('压缩成功！');window.opener.location.href=window.opener.location.href;</script>");
//解压文件夹
UnZipClass unZip = new UnZipClass();
unZip.UnZip(zipedPath+ ".zip", @"c: emp"); //要解压文件夹的路径(包括文件名)和解压路径(temp文件夹下的文件就是输入路径文件夹下的文件)
this.Response.Write("<script>alert('解压成功！');window.opener.location.href=window.opener.location.href;</script>");
}
}
}
}
本方法经过测试，均已实现。
