在EventArgs中使用错误信息调用C# Wuapi BeginInstall回调

Question

我正在写一个程序，可以通过wsusscn2.cab在离线环境中进行windows更新。

当我想要关于更新进行得如何的反馈时，我使用异步BeginInstall方法。我看到的问题是在eventArgs参数中使用相同的更新信息调用了两次回调，这也意味着一些更新不会被报告。每次运行时更新索引加倍或丢失的情况各不相同。有时它甚至没有问题。

我确实做了一个简短的测试程序来玩弄一些东西，代码如下。该程序是在Windows101909的VMWare工作站上运行的，它的查找Office2010更新，因为我有一个未更新的SP2安装尝试。

    static void Main(string[] args)
    {
        Console.WriteLine("Debug");
        Console.WriteLine(String.Format("Debugger is Attached:{0}", Debugger.IsAttached));

        Update();
        Console.Write("Done!");
        Console.ReadKey();
    }

    static void Update()
    {
        EventWaitHandle waitHandle = new EventWaitHandle(false, EventResetMode.ManualReset);
        OnProgressChange onProgress = new OnProgressChange(waitHandle);
        OnComplete onComplete = new OnComplete(waitHandle);
        State state = new State();

        UpdateSession session = new UpdateSession();
        UpdateServiceManager serviceManager = session.CreateUpdateServiceManager();
        IUpdateService updateService = serviceManager.AddScanPackageService("Offline Sync Service", @"C:\wsusscn2.cab",1);
        Console.WriteLine("Adding scanpackageservice complete");

        IUpdateSearcher searcher = session.CreateUpdateSearcher();
        searcher.ServerSelection = ServerSelection.ssOthers;
        searcher.ServiceID = updateService.ServiceID;
        
        ISearchResult result = searcher.Search("IsInstalled=0");
        Console.WriteLine("Search complete");

        IUpdateInstaller installer = session.CreateUpdateInstaller();
        installer.ClientApplicationID = "TEST";
        installer.Updates = new UpdateCollection();
        foreach (IUpdate update in result.Updates)
        {
            int i = installer.Updates.Add(update);
            Console.WriteLine(String.Format("{0,2} - Adding: {1}", i, update.KBArticleIDs[0]));                            
        }

        installer.ClientApplicationID = "TEST";

        IInstallationJob installationJob = installer.BeginInstall(onProgress, onComplete, state);
        waitHandle.WaitOne();
        IInstallationResult installationResult = installer.EndInstall(installationJob);
        serviceManager.RemoveService(updateService.ServiceID);
    }
}

public class State
{

}

public class OnProgressChange : IInstallationProgressChangedCallback
{
    EventWaitHandle eventWait;
    int Counter = 0;
    public OnProgressChange(EventWaitHandle handle)
    {
        eventWait = handle;
    }
    public void Invoke(IInstallationJob installationJob, IInstallationProgressChangedCallbackArgs callbackArgs)
    {
        int CurrentUpdateIndex = callbackArgs.Progress.CurrentUpdateIndex;
        Thread.Sleep(500); // Test delay
        string Title = installationJob.Updates[CurrentUpdateIndex].Title;
        string ID = installationJob.Updates[CurrentUpdateIndex].KBArticleIDs[0];
        Console.WriteLine(String.Format("Index: {0,2} - ID: {1} --- Args {2} - Control:{3}", CurrentUpdateIndex, ID, callbackArgs.Progress.CurrentUpdateIndex,Counter++==CurrentUpdateIndex));
    }
}

public class OnComplete : IInstallationCompletedCallback
{
    EventWaitHandle eventWait;
    public OnComplete(EventWaitHandle handle)
    {            
        eventWait = handle;
    }        
    public void Invoke(IInstallationJob installationJob, IInstallationCompletedCallbackArgs callbackArgs)
    {
        eventWait.Set();
        Console.WriteLine("In End");
    }
}

程序的典型结果如下所示：

正如您所看到的，updateindex 10丢失了，11被报告了两次。12和13也是如此。这其中有多少以及哪一个在不同的运行中有所不同。

我所看到的是，如果我在没有附加调试器的情况下运行，它可以在更多的测试运行中工作。如果我运行一次发布，那么成功率接近100%

我希望我已经很好地解释了这一点，并希望我能在这方面得到一些帮助，因为我已经用完了我所有的想法。

也是我在这里的第一篇文章，所以我也会很高兴地在我的文章中获得一些反馈:)

回调不可靠。更新完成后，您可以检查要安装的更新的状态，如下所示：

IInstallationProgress jobProgress = job.GetProgress();

for (int updateindex = 0; updateindex < installer.Updates.Count; updateindex++)
{
    IUpdateInstallationResult updateInstallResult = jobProgress.GetUpdateResult(updateindex);

    switch (updateInstallResult.ResultCode)
    {
        case OperationResultCode.orcNotStarted:
            // ....
            break;
        
        case OperationResultCode.orcInProgress:
            // ....
            break;
        
        case OperationResultCode.orcSucceeded:
            // ....
            break;
        
        case OperationResultCode.orcSucceededWithErrors:
            // ....
            break;
        
        case OperationResultCode.orcFailed:
            // ....
            break;
        
        case OperationResultCode.orcAborted:
            // ....
            break;
    }

}
