C＃：如何打开选择了多个文件的Windows资源管理器窗口
在Windows Media Player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。
所以我们假设我们的库中有一堆mp3文件，其中有三个是：
- Z：\ Music \ Thursday Blues \ 01。 我希望它是星期五.mp3
- Z：\ Music \ Counting Sheep \ 01。 绵羊＃1.mp3
- Z：\ Music \ Counting Sheep \ 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）并打开文件位置，则会弹出两个浏览器窗口。 一个将是带有01的Z：\ Music \ Thursday Blues文件夹。 我希望它是friday.mp3选中，另一个将是* Z：\ Music \ Counting Sheep **文件夹，两个01. Sheep＃1。 mp3和02.选择绵羊＃2.mp3 。
我怎样才能在C＃中自己做这个？ 我们有一个应用程序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，在创建这些文件并准备好查看时选择这些文件。 目前我只是做Process.Start(path) ，这有效，但我也希望能够突出显示那些特定的文件。 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= /这里是否有任何微软员工可以弄清楚如何做到这一点？ （一个）
在一位同事遇到问题后寻找答案我没有找到，所以我写了一个小class来做这件事。 代码在Gist上 ，我将在本文末尾粘贴curent版本。
使用示例文件，语法将为：
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，我的代码存在一些限制，主要是：
- 未在桌面上进行选择
- 父目录必须是目录或驱动器，因此您无法在“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：

免责声明：我认为VirtualBlackFox的答案比我的好，虽然它目前的票数较少，所以向下滚动并先阅读那个:)
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")
（我认为如果文件路径有空格，你可能需要转义引号）。

（根据这个问题的几个答案编译）
更难的方法，但更有可能工作，从这个答案的另一个问题 ：
使用shell函数SHOpenFolderAndSelectItems
下面是一些示例代码，展示了如何在C / C ++中使用该函数，而无需进行错误检查：
//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);
尝试开始：
explorer.exe /select,Z:\Music\Thursday Blues\01. I wish it was friday.mp3
也许您可以使用ProcessExplorer找出从Media Player启动explorer.exe时使用的参数？
问候，
Sebastiaan
总结一下 ：使用Process.Start是不可能的

flashk的答案 “这应该是可以使用shell函数SHOpenFolderAndSelectItems ”似乎对我来说可能，但我还没累呢
这是一个古老的问题，但是当我在谷歌上搜索相似时首先出现，所以我试图让结论更容易找到。
