ClickOnce部署CheckForDetailedUpdate引发异常 [英] ClickOnce deployment CheckForDetailedUpdate throws an exception

问题描述

我有一个24/7全天候运行的应用程序。它是通过 ClickOnce 部署的，需要自行检查和下载更新。它在应用程序启动时和晚上的计划时间检查更新。

I have an application that's running 24/7 without attendance. It's deployed via ClickOnce and needs to check and download updates by itself. It checks for updates at application startup and at scheduled time at night. When it does it on startup, it works perfectly fine.

但是，当它在计划的时间执行时，它崩溃了。在两种情况下，它都使用完全相同的代码。它可以在Windows 7下运行，并且可能与 UAC 有关。我在想，也许它在计算机处于空闲状态时无法访问文件系统？我真的需要解决这个问题。以下是异常详细信息：

However, when it does it at scheduled time, it crashes. In both cases it's using exactly the same piece of code. It's running under Windows 7 and might have something to do with UAC. I'm thinking that maybe it cannot access file system when computer is at idle state? I really need to fix that. Here are the exception details:

编辑：我认为原因可能是系统空闲一段时间后，硬盘驱动器已关闭。在我检查更新（使用C＃）之前，是否可以通过编程方式打开硬盘驱动器？

I think the cause might be that the hard disk drive is turning off after some time of the system being idle. Is there a way to programatically turn on the hard disk drive before I check for updates (using C#)?

推荐答案

我将在此处放置此链接仅供参考：链接到MSDN论坛。根据它的说法，这是ClickOnce内部的一个错误，该错误导致在调用CheckForDetailedUpdate（）函数一定次数后出现此错误。

I will put this link here just for the record: link to MSDN forum. According to it, it's a bug in ClickOnce internals which causes this error to appear after certain number of calls to the CheckForDetailedUpdate() function.
