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：

复制代码代码如下:

<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：

复制代码代码如下:

<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

复制代码代码如下:

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:

复制代码代码如下:

<httpModules> 
<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

复制代码代码如下:

<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

复制代码代码如下:

<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

复制代码代码如下:

<location path="Default.aspx" > 
<system.web> 
<neatUpload useHttpModule="true" /> 
<httpRuntime maxRequestLength="2097151" executionTimeout="3600" useFullyQualifiedRedirectUrl="true" /> 
</system.web> 
</location> 
</configuration>
