visual-studio - 我可以从 Visual Studio "Find Symbol Results"窗口复制多行吗？

Question

有谁知道如何将 Visual Studio“查找符号结果”窗口中的所有行复制到剪贴板上？您可以复制一行，但我想全部复制它们。

我不敢相信我是第一个想要这样做的人，但我什至找不到关于这个明显缺失的功能的讨论。

Answer 1

下面是一些使用 .Net 自动化库将所有文本复制到剪贴板的代码。

开始新的WinForms项目，然后添加以下引用:

WindowsBase

UIAutomationTypes

UIAutomationClient

System.Xaml

介绍核心

演示框架

系统管理

该代码还解释了如何在 Visual Studio 中设置菜单项以将内容复制到剪贴板。

编辑: UI 自动化仅返回可见的树 View 项。因此，要复制所有项目，将查找符号结果窗口设置为前景，然后设置 {PGDN}发送，并复制下一批项目。重复此过程，直到找不到新项目。最好使用 ScrollPattern ，但是它抛出了 Exception尝试设置滚动时。

编辑 2:试图通过在单独的线程上运行来提高 AutomationElement FindAll 的性能。在某些情况下似乎很慢。

编辑 3:通过使 TreeView 窗口非常大来提高性能。可以在大约 10 秒内复制大约 400 个项目。

编辑 4:处理对象实现 IDisposable .更好的消息报告。更好地处理流程参数。将窗口恢复到原来的大小。

// This program tries to find the 'Find Symbol Results' window in visual studio
// and copy all the text to the clipboard.
//
// The Find Symbol Results window uses a TreeView control that has the class name 'LiteTreeView32'
// In the future if this changes, then it's possible to pass in the class name as the first argument.
// Use TOOLS -> Spy++ to determine the class name.
//
// After compiling this code into an Exe, add a menu item (TOOLS -> Copy Find Symbol Results) in Visual Studio by:
// 1) TOOLS -> External Tools...
//      (Note: in the 'Menu contents:' list, count which item the new item is, starting at base-1).
//      Title: Copy Find Symbol Results
//      Command: C:\<Path>\CopyFindSymbolResults.exe             (e.g. C:\Windows\ is one option)
// 2) TOOLS -> Customize... -> Keyboard... (button)
//      Show Commands Containing: tools.externalcommand
//      Then select the n'th one, where n is the count from step 1).
