Can I disable window autoplay function programatically with C#/.NET?

Does anybody know a way to deactivate the autoplay function of windows using c#/.NET?
有人知道使用 c#/.NET 停用 windows 自动播放功能的方法吗？

A little summary, for all the others looking for a good way to disable/supress autoplay. So far I've found 3 methods to disable autoplay programatically:
一个小总结，对于所有其他正在寻找禁用/抑制自动播放的好方法的人。到目前为止，我已经找到了 3 种以编程方式禁用自动播放的方法：
- Intercepting the QueryCancelAutoPlay message
- Using the Registry
- Implementing the COM Interface IQueryCancelAutoPlay
- 拦截QueryCancelAutoPlay消息
- 使用注册表
- 实现 COM 接口IQueryCancelAutoPlay
In the end I chose the 3rd method and used the IQueryCancelAutoPlay interface because the others had some signifcant disadvantages:
最后我选择了第三种方法并使用了 IQueryCancelAutoPlay 接口，因为其他方法有一些明显的缺点：
- The first method (QueryCancelAutoPlay) was only able to suppress autoplay if the application window was in the foreground, cause only the foreground window receives the message
- Configuring autoplay in the registry worked even if the application window was in the background. The downside: It required a restart of the currently running explorer.exeto take effect...so this was no solution to temporarily disable autoplay.
- 第一种方法（QueryCancelAutoPlay）只能在应用程序窗口在前台时才能抑制自动播放，导致只有前台窗口收到消息
- 即使应用程序窗口在后台，在注册表中配置自动播放也能工作。缺点：它需要重新启动当前正在运行的explorer.exe才能生效......所以这不是暂时禁用自动播放的解决方案。
Examples for the implementation
实施示例
1. QueryCancelAutoPlay
1.查询取消自动播放
- Suppressing AutoRun Programmatically(MSDN article)
- CodeProject: Preventing a CD from Auto-Playing
- Canceling AutoPlay from C#
Note: If your application is using a dialog box you need to call SetWindowLong(signature) instead of just returning false. See herefor more details)
注意：如果您的应用程序正在使用对话框，您需要调用SetWindowLong（签名）而不是仅仅返回 false。有关更多详细信息，请参见此处）
2. Registry
2. 注册表
Using the registry you can disables AutoRun for specified drive letters (NoDriveAutoRun) or for a class of drives (NoDriveTypeAutoRun)
使用注册表，您可以禁用指定驱动器号 (NoDriveAutoRun) 或一类驱动器 ( NoDriveTypeAutoRun) 的AutoRun

3. IQueryCancelAutoPlay

- Reference for the IQueryCancelAutoPlayinterface on MSDN
- IQueryCancelAutoPlay only called once?(Example implementatio, also read comments)
- AutoPlayController(another implementation, not tested)

RegisterWindowMessage is a Win32 API call. So you will need to use PInvoke to make it work..
RegisterWindowMessage 是一个 Win32 API 调用。所以你需要使用 PInvoke 来让它工作..
using System.Runtime.InteropServices;
class Win32Call
{
[DllImport("user32.dll")]
public static extern int RegisterWindowMessage(String strMessage);
}
// In your application you will call
Win32Call.RegisterWindowMessage("QueryCancelAutoPlay");
From here(The Experts-Exchange link at the top). There is additional help on that site with some more examples that may be a little more comprehensive than the above. The above does however solve the problem.
从这里开始（顶部的专家交流链接）。该站点上还有其他帮助，其中包含更多示例，这些示例可能比上述示例更全面一些。不过以上确实解决了问题。

Try this code work for me :) For more info check out this reference link : http://www.pinvoke.net/default.aspx/user32.registerwindowmessage
试试这个代码对我有用:) 有关更多信息，请查看此参考链接：http: //www.pinvoke.net/default.aspx/user32.registerwindowmessage

[DllImport("user32.dll")]
static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
*/
protected override void WndProc(ref Message m)
{
//calling the base first is important, otherwise the values you set later will be lost
base.WndProc (ref m);
//if the QueryCancelAutoPlay message id has not been registered...
if (queryCancelAutoPlay == 0)
queryCancelAutoPlay = RegisterWindowMessage("QueryCancelAutoPlay");
//if the window message id equals the QueryCancelAutoPlay message id
if ((UInt32)m.Msg == queryCancelAutoPlay)
{
/* only needed if your application is using a dialog box and needs to

SetWindowLong(this.Handle, 0, 1);

m.Result = (IntPtr)1;
}
} //WndProc
