【中文标题】C#:如何打开选择了多个文件的 Windows 资源管理器窗口【英文标题】:C#: How to open Windows Explorer windows with a number of files selected 【发布时间】:2010-11-07 14:01:48 【问题描述】:在 Windows Media Player 的库中,您可以选择一个或多个音乐文件。然后您可以右键单击并在其上下文菜单中选择打开文件位置。这将为文件所在的每个目录打开一个 Windows 资源管理器窗口,并为您选择文件。
假设我们的库中有一堆 mp3 文件,其中三个是:
Z:\Music\Thursday Blues\01。我希望是friday.mp3 Z:\音乐\数羊\01。绵羊#1.mp3 Z:\音乐\数羊\02。绵羊#2.mp3如果我们选择这三个(在所有这些都可见的视图中)并执行打开文件位置,则会弹出两个资源管理器窗口。一个是 Z:\Music\Thursday Blues 文件夹,01。我希望它是 friday.mp3 被选中,而另一个将是 *Z:\Music\Counting Sheep** 文件夹,01.绵羊#1.mp3 和 02。 Sheep #2.mp3 已选中。
我自己如何在 C# 中做到这一点?我们有一个应用程序要将数据导出为各种格式,例如 CSV 和 Excel,我想打开资源管理器窗口,并在创建这些文件并准备好查看时选择这些文件。目前我只做Process.Start(path)
,这是可行的,但我也希望能够突出显示这些特定文件。会使刚刚创建的文件更加明显。
Windows Media Player 做得很好...我也想这样做 =/ 这里有微软员工可以弄清楚如何做到这一点吗? (一)
【问题讨论】:
【参考方案1】:在同事遇到问题后寻找答案,但我没有找到,所以我写了一个小班来做这件事。代码is on Gist,我将在本文末尾粘贴当前版本。
使用您的示例文件,语法将是:
ShowSelectedInExplorer.FilesOrFolders(
@"Z:\Music\Thursday Blues\01. I wish it was friday.mp3",
@"Z:\Music\Counting Sheep\01. Sheep #1.mp3",
@"Z:\Music\Counting Sheep\02. Sheep #2.mp3"
);
与低级API相比,我的代码有一些限制,主要是:
未实现在桌面上选择 父目录必须是目录或驱动器,因此不能在我的电脑文件夹中选择多个驱动器。无论如何,这里是 ShowSelectedInExplorer 类的源代码:

【讨论】:
这是否适用于分布在多个文件夹中的更多文件? 我修复了添加此功能的代码,它现在在这种情况下会打开多个资源管理器窗口。 @m0s:公共域或 BSD 2 子句,我并不真正关心 API 包装器。【参考方案2】:免责声明:我认为VirtualBlackFox's answer 比我的要好,尽管目前它的票数较少,所以请向下滚动并先阅读:)
简单的方法(可能不适用于所有平台):
Process.Start(String, String)
第一个参数是应用程序,第二个参数是应用程序的命令行参数..
例如:
Process.Start("explorer.exe",
"/select,Z:\Music\Thursday Blues\01. I wish it was friday.mp3")
Process.Start("explorer.exe",
"/select,Z:\Music\Counting Sheep\01. Sheep #1.mp3 /select,Z:\Music\Counting Sheep\02. Sheep #2.mp3")
(如果文件路径有空格,我认为您可能需要在文件路径周围使用转义引号)。

(根据this question的几个答案编译)
更难的方法,但更有可能奏效,取自this answer to another question:
使用shell函数SHOpenFolderAndSelectItems
以下是一些示例代码,展示了如何在 C/C++ 中使用该函数,无需进行错误检查:
//Directory to open
ITEMIDLIST *dir = ILCreateFromPath(_T("C:\\"));
//Items in directory to select
ITEMIDLIST *item1 = ILCreateFromPath(_T("C:\\Program Files\\"));
ITEMIDLIST *item2 = ILCreateFromPath(_T("C:\\Windows\\"));
const ITEMIDLIST* selection[] = item1,item2;
UINT count = sizeof(selection) / sizeof(ITEMIDLIST);
//Perform selection
SHOpenFolderAndSelectItems(dir, count, selection, 0);
//Free resources
ILFree(dir);
ILFree(item1);
ILFree(item2);
【讨论】:
最后一个不起作用,因为没有 Process.Start(string, string, string) 这样的东西。这些参数是否应该以某种方式在同一个字符串中? 是的,你是对的。我回答后意识到并更新了答案;现在可以用了吗? 嗯。它会运行,但只会打开一个资源管理器窗口并选择第一个文件。 在这种情况下,可能无法通过此方法完成多个文件。不知道从那里去哪里,除非你想通过这个解决方法:***.com/questions/9355/…【参考方案3】:尝试开始这个:
explorer.exe /select,Z:\Music\Thursday Blues\01. I wish it was friday.mp3

适用于一个文件,但如何处理多个文件?【参考方案4】:总结:无法使用 Process.Start
来自: programatically-select-multiple-files-in-windows-explorer
flashk's answer of "This should be possible with the shell function SHOpenFolderAndSelectItems
" 对我来说似乎可行,但我没有厌倦它
这是一个老问题,但出现了 第一次当我在谷歌搜索类似的时候,所以 我试图得出结论 更容易找到。
【讨论】:
【参考方案5】:也许您可以使用 ProcessExplorer 找出从 Media Player 启动 explorer.exe 时使用了哪些参数?
【讨论】:
首先设置资源管理器,以便资源管理器的每个实例都在新进程中启动。然后从媒体播放器中打开文件。在 ProcessExplorer 中,您应该看到媒体播放器的子进程。双击它,完整的命令行应该会显示在属性的某处。 这就是我尝试过的......但没有弹出资源管理器的新实例:S Windows 7 是否忽略该设置或其他什么? 抱歉,我还没有在 Windows 7 上尝试过。如果你手动启动一个新的资源管理器,你会得到一个新的进程吗? 我相信该选项会在同一进程中打开所有文件夹,但与任务栏分开。 (我说的是“在单独的进程中启动文件夹窗口”的选项。如果有一个选项可以单独打开每个窗口,请随时启发我!)以上是关于C#:如何打开选择了多个文件的 Windows 资源管理器窗口的主要内容,如果未能解决你的问题,请参考以下文章
