这段时间写了个asp.net 上传大文件控件。经过测试，在ie中可显示进度条。特此共享，望广大网友多提意见。 大文件上传控件（包含进度条）
使用说明如下：
<summary>
上传进度条控件
</summary>
<example>
Web.config 配置
<?xml version="1.0"?>
<configuration>
<configSections>
<!--上传节点-->
<sectionGroup name="slickUpload">
<section name="uploadLocationPRovider" type="Common.SlickUpload.Configuration.UploadLocationProviderHandler, Common"/>
</sectionGroup>
</configSections>
<system.web>
<httpRuntime maxRequestLength="2024000" executionTimeout="300"/>
<httpHandlers>
<add verb="*" path="CommonToolsASHX.ashx" type="Common.Web.AppControl.CommonToolsASHX, Common" />
<add verb="*" path="CommonToolsASHX_XML.ashx" type="Common.Web.AppControl.CommonToolsASHX_XML, Common" />
</httpHandlers>
<!--上传Modules-->
<httpModules>
<add name="HttpUploadModule" type="Common.SlickUpload.HttpUploadModule, Common"/>
</httpModules>
</system.web>
<appSettings>
<!--上传临时路径-->
<add key="uploadPath" value="c:\TDdownload\temp"/>
<!--许可上传页面，多个页面用';'分开-->
<add key="HttpUploadModulePageGoOn" value="Upload.aspx;"/>
</appSettings>
</configuration>
ASPX页面
//顶部
<%@ Register Assembly="Common" Namespace="Common.Web.AppControl" TagPrefix="cc1" %>
//form内
<asp:FileUpload ID="fileUploadFile" runat="server" />
<asp:Button ID="BtnUpload" runat="server" OnClick="Button1_Click" Text="Upload" />
<asp:HyperLink ID="hyCancel" runat="server">Cancel</asp:HyperLink>
<cc1:WebUploadProgressBar ID="WebUploadProgressBarControl" runat="server" UploadPath="C:\TDdownload"></cc1:WebUploadProgressBar>
ASPX对应的CS代码
protected void Page_Load(object sender, EventArgs e)
{
//绑定上传客户端javascript事件
this.BtnUpload.OnClientClick = this.WebUploadProgressBarControl.GetUploadClick_Javascript;
//绑定上传取消客户端javascript事件
this.hyCancel.NavigateUrl = "javascript:" + this.WebUploadProgressBarControl.GetUploadCancelClick_Javascript;
}
protected void BtnUpload_Click(object sender, EventArgs e)
{
//上传文件
this.WebUploadProgressBarControl.SaveUploadFiles();
}
</example>
<remarks>必须在IIS站点下设置端口或虚拟目录方可测试通过，又问题请和zljGood@hotmail.com联系</remarks>
