NeatUpload的安装使用

2014-07-05  悟静

版本:NeatUpload-1.2.32,用于文件上传。可传大文件。

 

1.VS工具箱中点右键选“选择项”…… Brettle.Web.NeatUpload.dll添加到工具箱。

可以在添加后的工具箱看到相应控件。

 

2.新建web项目。将NeatUpload复制到项目根目录。

3.修改Web.config

<?xml version="1.0encoding="utf-8"?>

 

<configuration>

 

    <configSections>

        <sectionGroup name="system.web">

            <section name="neatUploadtype="Brettle.Web.NeatUpload.ConfigSectionHandler, Brettle.Web.NeatUploadallowLocation="true" />

        </sectionGroup>

    </configSections>

 

    <appSettings/>

    <connectionStrings/>

 

    <system.web>

        <neatUpload useHttpModule="falsemaxNormalRequestLength="4096maxRequestLength="2097151defaultProvider="FilesystemUploadStorageProvider">

            <providers>

                <add name="FilesystemUploadStorageProvider"

                type="Brettle.Web.NeatUpload.FilesystemUploadStorageProvider, Brettle.Web.NeatUpload" />

            </providers>

        </neatUpload>

        <compilation debug="false">

        </compilation>

        <authentication mode="Windows" />

        <httpModules>

            <!--如果不加这httpmodules,进度条不显示-->

           <add name="UploadHttpModuletype="Brettle.Web.NeatUpload.UploadHttpModule, Brettle.Web.NeatUpload"/>

        </httpModules>

    </system.web>

    <location path="Default.aspx" >

        <system.web>

            <neatUpload useHttpModule="true" />

            <httpRuntime maxRequestLength="2097151executionTimeout="3600useFullyQualifiedRedirectUrl="true" />

        </system.web>

    </location>

</configuration>

 

 

现在可以拖拽控件开始编程了。

4.aspx页面代码如下:

<head runat="server">

    <title> NeatUpload </title>

    <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>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <Upload:InputFile ID="AttachFile" runat="server" />

   <asp:Button ID="Upload" runat="server" Text="Upload"

            OnClientClick="ToggleVisibility('ProgressBar','on')" onclick="Upload_Click" />

       <div id="ProgressBar" >

       <Upload:ProgressBar ID="pbProgressBar" runat='server' Inline="true" Width="280px"

               Height="50px">

       </Upload:ProgressBar>

   </div>

   </div>

    </form>

</body>

</html>

 

设计页面如下:

 

5.按钮事件处理函数:

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;

                }

            }

        }

 

做到这里程序就可以运行的了。

默认的进度条的样式是可以修改的。

主要修改default.cssProgress.aspx及ProgressBar控件的属性

 

default.css修改部分:

.ProgressDisplay .ProgressBar {

      background-color#D7E5F7;

      background-imageurl("/11.gif")/*进度条背景图片*/

      height:20px;

}

#normalInProgress{

     colorRed;      /*进度条字体颜色*/

}

#completed{

     color:Blue;   /*上传完成的字体颜色*/

}

 

Progress.aspx是显示进度条的核心文件,相关数据的显示都在里面。

<td id="barTd" >

              <div id="statusDiv" runat="server" class="StatusMessage">

 

                   <Upload:DetailsSpan id="normalInProgress" runat="server" WhenStatus="NormalInProgress" style="font-weightnormalwhite-spacenowrap;">                                <%--  正在上传时显示的   --%>

                   <%-- <%# FormatCount(BytesRead) %>/<%# FormatCount(BytesTotal) %> <%# CountUnits %> --%>

                  (<%# String.Format("{0:0%}", FractionComplete) %>) at <%# FormatRate(BytesPerSec) %>

                   <%-- - <%# FormatTimeSpan(TimeRemaining) %> left        --%>

                   </Upload:DetailsSpan>

 

                   <Upload:DetailsSpan id="chunkedInProgress" runat="server" WhenStatus="ChunkedInProgress" style="font-weightnormalwhite-spacenowrap;">       

                    <%# FormatCount(BytesRead) %> <%# CountUnits %>

                       at <%# FormatRate(BytesPerSec) %>

                       - <%# FormatTimeSpan(TimeElapsed) %> elapsed

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="completed" runat="server" WhenStatus="Completed">

                       <%--  上传完成时显示的   --%>

完成了: <%# FormatCount(BytesRead) %> <%# CountUnits %>

                       at <%# FormatRate(BytesPerSec) %>

                       took <%# FormatTimeSpan(TimeElapsed) %>

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="cancelled" runat="server" WhenStatus="Cancelled">

                       Cancelled!

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="rejected" runat="server" WhenStatus="Rejected">

                       Rejected: <%# Rejection != null ? Rejection.Message : "" %>

                   </Upload:DetailsSpan>

                   <Upload:DetailsSpan id="error" runat="server" WhenStatus="Failed">

                       Error: <%# Failure != null ? Failure.Message : "" %>

                   </Upload:DetailsSpan>

                   <Upload:DetailsDiv id="barDetailsDiv" runat="server" UseHtml4="true"

                        Width='<%# Unit.Percentage(Math.Floor(100*FractionComplete)) %>' class="ProgressBar"></Upload:DetailsDiv> 

              </div>

         </td>
