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
%26lt;summary%26gt;
上传进度条控件
%26lt;/summary%26gt;
%26lt;example%26gt;
Web.config 配置
%26lt;?xml version="1.0"?%26gt;
%26lt;configuration%26gt;
%26lt;configSections%26gt;
%26lt;!--上传节点--%26gt;
%26lt;sectionGroup name="slickUpload"%26gt;
%26lt;section name="uploadLocationProvider" type="Common.SlickUpload.Configuration.UploadLocationProviderHandler, Common"/%26gt;
%26lt;/sectionGroup%26gt;
%26lt;/configSections%26gt;
%26lt;system.web%26gt;
%26lt;httpRuntime maxRequestLength="2024000" executionTimeout="300"/%26gt;
%26lt;httpHandlers%26gt;
%26lt;add verb="*" path="CommonToolsASHX.ashx" type="Common.Web.AppControl.CommonToolsASHX, Common" /%26gt;
%26lt;add verb="*" path="CommonToolsASHX_XML.ashx" type="Common.Web.AppControl.CommonToolsASHX_XML, Common" /%26gt;
%26lt;/httpHandlers%26gt;
%26lt;!--上传Modules--%26gt;
%26lt;httpModules%26gt;
%26lt;add name="HttpUploadModule" type="Common.SlickUpload.HttpUploadModule, Common"/%26gt;
%26lt;/httpModules%26gt;
%26lt;/system.web%26gt;
%26lt;appSettings%26gt;
%26lt;!--上传临时路径--%26gt;
%26lt;add key="uploadPath" value="c:\TDdownload\temp"/%26gt;
%26lt;!--许可上传页面，多个页面用';'分开--%26gt;
%26lt;add key="HttpUploadModulePageGoOn" value="Upload.aspx;"/%26gt;
%26lt;/appSettings%26gt;
%26lt;/configuration%26gt;
ASPX页面
//顶部
%26lt;%@ Register Assembly="Common" Namespace="Common.Web.AppControl" TagPrefix="cc1" %%26gt;
//form内
%26lt;asp:FileUpload ID="fileUploadFile" runat="server" /%26gt;
%26lt;asp:Button ID="BtnUpload" runat="server" OnClick="Button1_Click" Text="Upload" /%26gt;
%26lt;asp:HyperLink ID="hyCancel" runat="server"%26gt;Cancel%26lt;/asp:HyperLink%26gt;
%26lt;cc1:WebUploadProgressBar ID="WebUploadProgressBarControl" runat="server" UploadPath="C:\TDdownload"%26gt;%26lt;/cc1:WebUploadProgressBar%26gt;
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();
}
%26lt;/example%26gt;
%26lt;remarks%26gt;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%26lt;/remarks%26gt;
