小编长期都在使用Visual Studio这个全球最强大的IDE（没有之一），但是有些时候，往往需要查找、或者是替换多行文本，这个时候，对于VS来说可能有点压力了，因为默认的替换只能支持单行文本（虽然宏里面的FindLine是可以支持多行查找的，但是不能多行替换，稍后会详细说明下）。
给 Visual Studio 2010 增加多行查找与多行替换功能（VS跨行查找替换：上篇）
这个图是增加多行查找与多行替换功能的效果图，还不错吧！
接下来，等小牛来介绍一下如何添加多行查找与多行替换功能？
只要几个步骤就可加入功能。
1. 在 VS 中打开 Macros Explorer(宏 资源管理器) ，在 工具–宏–宏资源管理器（或者快捷键Alt+F8）。
2. 在 宏资源管理器 的 MyMacros 中新建一个宏 MultilineSearch
3. 双击 MultilineSearch ，则显出 宏的IDE和生成的新宏的vb代码
4. 把 新宏的vb代码内容都删除，把如下代码拷进去

5. 将 System.Drawing.dll 加入 宏工程 的引用
6. 关闭宏IDE
操作完上面的6个步骤之后，你的VS2012就多了个多行搜索和替换文本的工具，效果图就是最上面的那个图。为了更方便大家学习，小牛打包了上面的这个vb代码，需要的，可以自己下载。
吾乐吧软件站补充说明：
小编在使用过程中发现，本文提供的这个方法虽然可以实现多行查找、多长替换文本，但是多行替换的时候，会出现一个问题：你不能把多行文本替换为多行文本（除非你手动写正则）。为了解决这个问题，小编专门想出了另一个更加有效的方法，请大家移步查看《给 Visual Studio 2010 增加多行查找与多行替换功能（VS跨行查找替换：下篇）》
