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>
