asp.net上传大文件控件 - asp.net 教程-

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：

<?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>
