asp.net 上传大文件控件

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>
