博客备份小工具3

接着 博客转发小工具2 ，又弄了一个第三版。主要功能有：博客备份到本地、浏览备份到本地的博客、关键字搜索本地的博客和转发博客可以选择个人分类 填写Tag标签。其实想了想，转发博客干嘛非要在本地客户端转发，直接在博客园的页面用js不就可以达到目的么。想是这么想，还没尝试。等我写完了这个博客就去试试。。继续回到这个小工具，说实在的本人做的这个小工具界面丑的那是、、反正就是很丑很丑啦。没办法，没有美工的那种艺术细胞。还有就是，整个功能其实真没什么技术含量，还是html的抓取，winfrom在工作中也没用过，就平时偶尔玩玩，望大神们勿喷~~。

不过我觉得这个小工具的作用：第一、可以用来备注自己的博客，自己留个底。第二、某些朋友的工作环境可能没有外网（我以前的公司就没有），这样的话可以用来备份一些博友的系类文章当资料。【要是可以的话，把系类文章导成dpf文档那就更爽了。可是我一直没成功~】。

也许有写人会说：啥啥啥的早就有类似的软件了。我不知道，我没用过，我觉得自己做的用着开心。就当练手吧。

开始说内容了。

功能二：浏览本地博客

1.递归加载目录下所以博客文件

（这个方法不行，如果文件多的话，会有点卡。以后要改成点击加载下层目录）

public TreeNodeCollection loadTree(string path, TreeNodeCollection treeS, bool isNe = true)
{
List<string[]> list = FileHelp.FileSystemInfo(path, "3");
string[] str = new string[] { "", "" };
if (list != null)
{

for (int i = 0, j = 0; i < list.Count; i++, j++)
{
if (list[i][0] == "imgs")
{
j--;
continue;
}
TreeNode tree1 = new TreeNode() { Text = list[i][0] };
treeS.Add(tree1);
loadTree(list[i][1], treeS[j].Nodes);
}
}
return treeS;
}

2.点击加载博客内容（这里使用到了webBrowser控件来显示博客内容）

#region 点击tree树  加载对应内容
/// <summary>
/// 点击tree树  加载对应内容
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
if (e.Action == TreeViewAction.ByMouse || e.Action == TreeViewAction.ByKeyboard)
{
htmlPath = FileHelp.PathBlogs + Forward.ForwardPath + e.Node.FullPath;
string html = FileHelp.GetFile(htmlPath);
HtmlAgilityPack.HtmlDocument docment = new HtmlAgilityPack.HtmlDocument();
docment.LoadHtml(html);
try
{
var text_html = docment.DocumentNode.SelectNodes("//div[@id='my_html_postBody']")[0].InnerHtml;
var mytext_url = docment.DocumentNode.SelectNodes("//div[@id='mytext_url']")[0].InnerHtml;
webBrowser1.DocumentText = text_html;
text_url.Text = mytext_url;
}
catch (Exception)
{ }
}
}
#endregion

功能三：本地浏览关键字搜索

搜索使用的Lucenne.net。这里面的水太深了。这里就使用到了点皮毛。这里给出一些资料地址。

1.首先在备份的时候就需要创建搜索索引。

/// <summary>
/// 创建索引
/// </summary>
/// <param name="analyzer"></param>
/// <param name="title"></param>
/// <param name="content"></param>
private static void AddIndex(IndexWriter writer, string title, string content, string filePath, string id, string mytext_BlogTitleName = "Blog", string ClickQuantity = "0")
{
try
{
// Field.Store.YES, Field.Index.ANALYZED, Lucene.Net.Documents.Field.TermVector.WITH_POSITIONS_OFFSETS));

Document doc = new Document();
doc.Add(new Field("Title", title, Field.Store.YES, Field.Index.ANALYZED));//存储且索引
//doc.Add(new Field("Content", content, Field.Store.YES, Field.Index.ANALYZED, Lucene.Net.Documents.Field.TermVector.WITH_POSITIONS_OFFSETS));// Field.Store.YES, Field.Index.ANALYZED));//存储且索引
doc.Add(new Field("Content", content, Field.Store.YES, Field.Index.ANALYZED));
doc.Add(new Field("filePath", filePath, Field.Store.YES, Field.Index.NOT_ANALYZED));//存储且索引
doc.Add(new Field("BlogTitleName", mytext_BlogTitleName, Field.Store.YES, Field.Index.NOT_ANALYZED));
doc.Add(new Field("id", id, Field.Store.YES, Field.Index.NOT_ANALYZED));
doc.Add(new Field("ClickQuantity", ClickQuantity, Field.Store.YES, Field.Index.NOT_ANALYZED));
//防止重复索引
writer.DeleteDocuments(new Term("id", id));
//AddTime
writer.AddDocument(doc);
}
catch (FileNotFoundException fnfe)
{
throw fnfe;
}
catch (Exception ex)
{
throw ex;
}
}

2.点击搜索

#region 点击搜索
private void but_select_Click(object sender, EventArgs e)
{
new Thread(delegate()
{
try
{
lab_meg.Text = "正在搜索.....";
var htm = "";
var list = LuceneHelp.SelectData(FileHelp.PathBlogs + "Index\\", txt_select.Text.Trim(), this.lab_meg);
var count = 150;
if (list.Count >= count)
{
var mess = MessageBox.Show("搜索结果过多，是否只显示前" + count + "条~", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Asterisk);
if (mess == System.Windows.Forms.DialogResult.Yes)
{
int index = 0;
foreach (var item in list)
{
index++;
htm += "<a name='click_load_file' href='#' filePath='" + item.FilePath + "'>" +
item.FileName + "</a><br/><div>" + item.Content
+ "<div><br/><div style='width:100%;text-align:right;'><span style='margin-right:20px;background-color:#e1d2d2'>作者["
+ item.BlogTitleName + "]  搜索(" + item.ClickQuantity + ")</span></div><br/><br/>";
if (index >= count)
break;
}
}
else
foreach (var item in list)
{
htm += "<a name='click_load_file' href='#' filePath='" + item.FilePath + "'>" +
item.FileName + "</a><br/><div>" + item.Content
+ "<div><br/><div style='width:100%;text-align:right;'><span style='margin-right:20px;background-color:#e1d2d2'>作者["
+ item.BlogTitleName + "]  搜索(" + item.ClickQuantity + ")</span></div><br/><br/>";
}

}
else
{
foreach (var item in list)
{
htm += "<a name='click_load_file' href='#' filePath='" + item.FilePath + "'>" +
item.FileName + "</a><br/><div>" + item.Content
+ "<div><br/><div style='width:100%;text-align:right;'><span style='margin-right:20px;background-color:#e1d2d2'>作者["
+ item.BlogTitleName + "]  搜索(" + item.ClickQuantity + ")</span></div><br/><br/>";
}
}
webBrowser1.DocumentText = htm;
htmlList = htm;
}
catch (Exception ex)
{
//MessageBox.Show(ex.Message);
lab_meg.Text = "搜索出错~" + ex.Message;
}
}).Start();
}
