If Icon.ExtractAssociatedIcon(filePath) is the only way to get icons in .NET && if it doesn't work for Drives and Directories (does it?) then how do you go about getting the icons for them?

换句话说，我想

foreach (string driveName in Directory.GetLogicalDrives())

{
    using (System.Drawing.Icon systemIcon = System.Drawing.Icon.ExtractAssociatedIcon(driveName))
    { ... }
}

^这显然是行不通的（仅适用于文件的工作）

^ this obviously doesn't work (works only for files)

我不知道 System.IO.Directory.Exists（文件）是正确的方式进行检测，如果硬盘存在，以及...

I'm not sure System.IO.Directory.Exists(file) is the right way for detecting if drives exist as well...

推荐答案

要在.NET应用程序做到这一点，你将不得不P /调用的 的SHGetFileInfo 功能从Windows API（它定义于 SHELL32.DLL ）。

To do this from a .NET application, you will have to P/Invoke the SHGetFileInfo function from the Windows API (it's defined in shell32.dll).

下面是一些示例code，显示如何做到这一点：获取相关的图标使用C＃
