如何将BrowseForFolder从VBScript移植到C#/WPF?

Set application = CreateObject("Shell.Application")
Set folder = application.BrowseForFolder(0, "Moo!", &h250, &h12) ' &h12 sets
' Network as the root folder.

因此,我添加了一个对表单的引用,并尝试使用FolderBrowserDialog执行此操作,但令我惊讶的是:

FolderBrowserDialog dialog = new FolderBrowserDialog();
dialog.RootFolder = /* The Environment.SpecialFolder enumeration doesn't have
a value Network! */
dialog.RootFolder = (Environment.SpecialFolder)0x12; /* This dirty trick doesn't
work too. */

然后,我在Windows API中查找了一个可执行此操作的pinvokable函数,但没有找到任何函数。
