我的asp.net静态页面生成

主要思路还是使用StreamReader获取远程url的数据流，然后写.html文件来静态输出。

主要类common.cs封装如下：

 1public class common
 2{
 3    public common()
 4    {
 5    }
 6    /**//// <summary>
 7    /// 接收数据流并生成html
 8    /// </summary>
 9    /// <param name="url">url或者数据流</param>
10    /// <param name="isAlreadyData">是否是数据流</param>
11    /// <param name="fna">生成文件</param>
12    /// <returns>是否成功</returns>
13    public bool CreateList(string url,bool isAlreadyData, string fna)
14    {
15        bool ok;
16        StreamWriter sw = null; //用来写文件
17        Encoding code = Encoding.GetEncoding("utf-8"); //定义编码 
18
19        string strHtml;
20        if (isAlreadyData == true)
21            strHtml = url;
22        else
23            strHtml=CommonXMLGetData(url);
24
25        //写入文件
26        try
27        {
28            sw = new StreamWriter(fna, false, code);
29            sw.Write(strHtml);
30            sw.Flush();
31            ok = true;
32        }
33        catch (Exception ex)
34        {
35            HttpContext.Current.Response.Write("<p>写入文件出错：" + ex.Message);
36            HttpContext.Current.Response.End();
37            ok = false;
38        }
39        finally
40        {
41            sw.Close();
42        }
43        return ok;
44    }
45
46    public string GetDataFromRemoteUrl(string url)
47    {
48        return CommonXMLGetData(url);
49    }
50    protected static string CommonXMLGetData(string url)
51    {
52        //准备生成
53        string strHtml;
54        Encoding code = Encoding.GetEncoding("utf-8"); //定义编码 
55        StreamReader sr = null; //用来读取流
56        //构造web请求，发送请求，获取响应
57        WebRequest HttpWebRequest = null;
58        WebResponse HttpWebResponse = null;
59        HttpWebRequest = WebRequest.Create(url);
60        try
61        {
62            HttpWebResponse = HttpWebRequest.GetResponse();
63        }
64        catch(Exception ex)
65        {
66            HttpContext.Current.Response.Write("出错信息：" + ex.Message);
67        }
68
69        //获得流
70        sr = new StreamReader(HttpWebResponse.GetResponseStream(), code);
71        strHtml = sr.ReadToEnd();
72        return strHtml;
73    }
74}

以下为页面文件news_list.aspx（前一段时间写的，那时还没有用到存储过程分页）

 

 1    <div id="article">
 2        <div id="left">
 3            <div id="navPosition">&middot;<a href="index.aspx">首页</a>&raquo;&middot;<asp:HyperLink ID="lnkNewsClassName" runat="server"></asp:HyperLink></div>
 4            <div id="articleList">
 5                <ul>
 6                    <asp:Repeater ID="rptNewsList" runat="server">
 7                        <ItemTemplate>
 8                        <li><asp:HyperLink ID="lnkNewsText" ForeColor="#003399" Text='<%# DataBinder.Eval(Container.DataItem,"News_Id")%>' NavigateUrl='<%# "news_info.aspx?news_id=" + DataBinder.Eval(Container.DataItem,"News_Id")%>' ToolTip='<%# "文章标题:" + DataBinder.Eval(Container.DataItem,"News_Title") + "\n发布时间:" + DataBinder.Eval(Container.DataItem,"News_PostTime") + "\n发布人:" + DataBinder.Eval(Container.DataItem,"News_PostAuthor") %>' Target="_blank" runat="server"></asp:HyperLink><asp:Label ID="lblArticleInfo" ForeColor="red" runat="server"></asp:Label><asp:Label ID="lblArticlePostTime" runat="server" CssClass="postTime"></asp:Label></li>
 9                        </ItemTemplate>
10                        <FooterTemplate>
11                        </FooterTemplate>

13                </ul>
14                <div id="articlePager">

18                    <asp:HyperLink ID="lnkLast" NavigateUrl="$lastPage$" runat="server">尾页</asp:HyperLink>
19                    <asp:LinkButton ID="lnkFirstPage" Text="首页" OnCommand="ChangePage" CommandName="FirstPage" runat="server"></asp:LinkButton>
20                    <asp:LinkButton ID="lnkPrePage" Text="上一页" OnCommand="ChangePage" CommandName="PrePage" runat="server"></asp:LinkButton>
21                    <asp:LinkButton ID="lnkNextPage" Text="下一页" OnCommand="ChangePage" CommandName="NextPage" runat="server"></asp:LinkButton>
22                    <asp:LinkButton ID="lnkLastPage" Text="尾页" OnCommand="ChangePage" CommandName="LastPage" runat="server"></asp:LinkButton>
23                    <asp:Label CssClass="pager" ID="lblPageInfo" runat="server"></asp:Label>
24                    <asp:DropDownList ID="ddlPageUrl" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlPageUrl_SelectedIndexChanged1"></asp:DropDownList>
25                </div>
26            </div>
27        </div>
28

其中带$...$标签的为页码标记。

以下是生成代码，生成内容包括这里的news_list.aspx和news_info.aspx文件，也就是所有关于news的文件。
