非常感谢 Brettle 的开源
支持.net 1.1 .NET 2.0
这里是 live demo
很不容易发现的，在.net下面要找个开源的东西真是难也。
当然大文件上传有很多组件比如ABCUPLOAD SlickUpload不过都不是开源都是商业代码带来的就是N多的$，所以。。。
安装办法
下载地址：http://www.brettle.com/neatupload#Download
1.在工具箱中添加Brettle.Web.NeatUpload.dll，可以看到工具箱中出现InputFile等控件。
2.复制文件夹NeatUpload到根目录.
3.拖放使用上传控件InputFile和进度条ProgressBar,添加上传文件的按钮.aspx页面代码如下：
<body> <form id="form1" runat="server"> <div> <upload:InputFile id="AttachFile" runat="server"></upload:InputFile> <asp:Button ID="Upload" runat="server" Text="Upload" OnClientClick="ToggleVisibility('ProgressBar','on')" OnClick="Upload_Click"/> <div id="ProgressBar" style="display:none;"><upload:progressbar id="pbProgressBar" runat="server" Inline="true" Width="500px" Height="100"> </upload:progressbar>
</div> </div> </form></body>
4.添加脚本代码ToggleVisiblity函数到页面上如下：
<script type="text/javascript" language="javascript"> function ToggleVisibility(id, type) { el = document.getElementById(id); if(el.style) { if(type == 'on') { el.style.display = 'block'; } else { el.style.display = 'none'; } } else { if(type == 'on') { el.display = 'block'; } else { el.display = 'none'; } } } </script>
5.给上传文件的按钮添加事件Upload_Click
protected void Upload_Click(object sender, EventArgs e)
{
string FileName = this.AttachFile.FileName;//获取上传文件的全路径 string ExtenName = System.IO.Path.GetExtension(FileName);//获取扩展名 string SaveFileName = System.IO.Path.Combine(Request.PhysicalApplicationPath, DateTime.Now.ToString("yyyyMMddhhmm") + ExtenName);//合并两个路径为上传到服务器上的全路径 if (this.AttachFile.ContentLength > 0)
{
try { this.AttachFile.MoveTo(SaveFileName, Brettle.Web.NeatUpload.MoveToOptions.Overwrite);
} catch (Exception ex) { throw ex; } }
}
6.在配置文件web.config中添加http模块声明:
<httpModules useFullyQualifiedRedirectUrl="true"> <add name="UploadHttpModule" type="Brettle.Web.NeatUpload.UploadHttpModule, Brettle.Web.NeatUpload" /> </httpModules>
7.需要在web.config进行其他一些设置才能保证完美
在<configuration>里面加入
<configSections> <sectionGroup name="system.web"> <section name="neatUpload" type="Brettle.Web.NeatUpload.ConfigSectionHandler, Brettle.Web.NeatUpload" allowLocation="true" /> </sectionGroup> </configSections>
在 <system.web>加入
<neatUpload useHttpModule="false" maxNormalRequestLength="4096" maxRequestLength="2097151" defaultProvider="FilesystemUploadStorageProvider"> <providers> <add name="FilesystemUploadStorageProvider" type="Brettle.Web.NeatUpload.FilesystemUploadStorageProvider, Brettle.Web.NeatUpload" /> </providers></neatUpload>
在<configuration>里面的后面位置加入
<location path="Default.aspx" > <system.web> <neatUpload useHttpModule="true" /> <httpRuntime maxRequestLength="2097151" executionTimeout="3600" useFullyQualifiedRedirectUrl="true" /> </system.web> </location></configuration>
