文章来源:http://www.aspxcs.net/HTML/1057051966.html
使用流程：
1、下载附件后，将web.config和default.aspx删除；【点击下载】
2、将附件中的Web项目进行生成发布；
3、建立自己的应用Web项目；
4、之后：
（1）将附件Web项目发布文件夹中的images，PDF，render，lib，PDFViewer.ascx拷贝到新建的web项目文件夹中； 
（2）将附件Web项目发布文件夹中bin目录下生成的PDFLibNet.dll，PDFViewASP.dll，StatefullScrollPanel.dll文件拷贝
到新建的web项目文件夹的bin目录中； 
新建Web项目的解决方案如下图所示： 
（3）在新建Web项目中将PDFViewer.ascx直接拖到需要使用该控件的页面，并在该页面中放一个FileUpload、一个Button、一个Label 
前台页面代码：
1. <form id="form1" runat="server">
2.
3. <div>
4.
5. <asp:FileUpload ID="FileUpload1" runat="server" Width="224px" />
6.
7. <asp:Button ID="Button1" runat="server" Text="View PDF"
8.
9. onclick="Button1_Click" />
10.
11. <asp:Label ID="ErrorLabel" runat="server" Text="" ForeColor="#CC0000" Visible="False"></asp:Label>
12.
13.
14.
15. </div>
16.
17. <uc1:PDFViewer ID="PDFViewer1" runat="server" />
18.
19. </form>
