一个C#写的可以下载自己blog到本地的小程序

blog不能备份怎么办，自己写一个。
基本原理是先根据输入的rss地址，获取rss文件，
private void downRss(string url)
        {
            txtContent.Text = "正在下载...";
            this.Refresh();
            try
            {
                WebClient MyWebClient = new WebClient();

                MyWebClient.Credentials = CredentialCache.DefaultCredentials;//获取或设置用于对向Internet资源的请求进行身份验证的网络凭据。               
                MyWebClient.DownloadFile(url, "output.xml");
            }
            catch (WebException webEx)
            {
                MessageBox.Show(webEx.Message.ToString());
            }

            txtContent.Text = "下载完成，正在读取文件...";
            this.Refresh();

            StreamReader sr = new StreamReader("output.xml");
            string strcontent = "";
            while (!sr.EndOfStream)
            {
                strcontent += sr.ReadLine();
            }

            sr.Close();
            txtContent.Text = strcontent;
        }解析从中取出每篇文章的标题和链接，可以显示在一个listView控件中，
private void xmlToLstView(string filename)
        {
            listView1.Items.Clear();
            //updateTreeView(txtUrl.Text);
            //updateTreeView("output.xml");
            XmlDocument tmpxmldoc = new XmlDocument(); //实例化XML文档
            tmpxmldoc.Load(filename); //加载XML文档
            XmlNodeList nodeList;
            nodeList = tmpxmldoc.SelectNodes("/rss/channel/item");
            try
            {
                for (int i = 0; i < nodeList.Count; i++)
                {
                    ListViewItem item = new ListViewItem(new string[]{
                                        nodeList[i].SelectSingleNode("title").InnerText,
                                        nodeList[i].SelectSingleNode("link").InnerText,
                                        nodeList[i].SelectSingleNode("pubDate").InnerText}
                                    );
                    listView1.Items.Add(item);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

然后根据listview中选中的项链接下载此文件。
private void downSelectPage()
        {
            for (int i = 0; i < listView1.Items.Count; i++)
            {
                if (this.listView1.Items[i].Checked)
                {
                    DirectoryInfo dir = new DirectoryInfo("Down");
                    if (!dir.Exists)
                    {
                        Directory.CreateDirectory("Down");//如果不存在，则创建子文件夹
                    }
                    string filename = Directory.GetCurrentDirectory() + "\\Down\\" + this.listView1.Items[i].SubItems[0].Text + ".html";
                    string url = this.listView1.Items[i].SubItems[1].Text;

                    try
                    {


                        txtContent.Text = "正在下载" + filename + "文件...";
                        this.Refresh();

                        WebClient MyWebClient = new WebClient();
                        MyWebClient.Credentials = CredentialCache.DefaultCredentials;//获取或设置用于对向Internet资源的请求进行身份验证的网络凭据。               
                        Byte[] pageData = MyWebClient.DownloadData(url);//从指定网站下载数据
                        string pageHtml = Encoding.Default.GetString(pageData);

                        FileStream fs = new FileStream(filename, FileMode.Create);
                        fs.Write(pageData, 0, pageData.Length);
                        fs.Close();

                        txtContent.Text = filename + "下载完成!";
                        this.Refresh();
                    }

                    catch (WebException webEx)
                    {
                        MessageBox.Show(webEx.Message.ToString());
                    }


                }

            }
        }
还有很多毛病，比如速度慢，不能下载其中的图片，不过暂时解决了blog备份问题。
源代码在此，可以改进的余地很大。
