文本搜索工具的制作过程之搜索
<div id="cnblogs_post_body"> 虽然在博客园注册账号很久了，但一直在做读者，刚审批通过博客也来写写随笔，当然水平有限，敬请谅解。第一篇博文就拿这几天刚做的一个小工具起篇吧，虽然相对比较简单，相信还有有需要的人的。
随着电脑上的东西越来越多，尤其是笔记，在需要的时候快速找到所需要的那个文本笔记还真是不好找，用windows的查找功能可以按文件名进行文件查找，要是记得文件名的一星半点找起来还是可以得，但要是要找的内容在文件名中没有体现的话，那找起来可就麻烦了，所以就需要有这么一个工具，通过匹配文本中得内容来查找所需的文件。

上图是该工具的一个布局，通过指定一个路径，指定相应的搜索类型和搜索关键字进行查询，关键字可以是正则表达式。
第一步，获取要搜索的目录，这个比较容易，使用FolderBrowserDialog让用户选择相应的文件夹，将路径显示在文本框中。代码如下：
<div class="cnblogs_code"> 1 string rootPath = string.Empty; 2//获取要搜索的根目录 3 private void btnPath_Click(object sender, EventArgs e) 4 { 5 FolderBrowserDialog fbd = new FolderBrowserDialog(); 6 if (fbd.ShowDialog() == DialogResult.OK) 7 { 8 rootPath = fbd.SelectedPath; 9 txtPath.Text = rootPath;10 }11 }
