Event Viewer reporting my C# application crashed through 'System.Environment.FailFast()'

My application is running on Windows Embedded Standard 7 and launches when the OS boots up.

Sometimes on the first load, I will get an Unknown Hard Error, and after checking the Event Viewer, I see a message of

The application requested process termination through System.Environment.FailFast(string message).
Message: Unrecoverable system error.

Needless to say, I of course have no calls to this function. I only seem to see this happen on Windows Embedded, and haven't seen this reproduced on a standard install of Windows.

I'm unsure of how to diagnose this or what 'fix' would be appropriate as I don't really know why it happens.

Edit:

The entire log in Event Viewer:

    Application: WinForm.exe

答案 0 :(得分:1)

如果你用反编译器查看代码,你会发现

    // System.IO.Packaging.Package
private void AddIfNoPrefixCollisionDetected(PackUriHelper.ValidatedPartUri partUri, PackagePart part)
{
    this._partList.Add(partUri, part);
    int num = this._partList.IndexOfKey(partUri);
    Invariant.Assert(num >= 0, "Given uri must be present in the dictionary");**
    string normalizedPartUriString = partUri.NormalizedPartUriString;
    string text = null;
    string text2 = null;
    if (num > 0)
    {
        text = this._partList.Keys[num - 1].NormalizedPartUriString;
    }
    if (num < this._partList.Count - 1)
    {
        text2 = this._partList.Keys[num + 1].NormalizedPartUriString;
    }
    if ((text != null && normalizedPartUriString.StartsWith(text, StringComparison.Ordinal) && normalizedPartUriString.Length > text.Length && normalizedPartUriString[text.Length] == PackUriHelper.ForwardSlashChar) || (text2 != null && text2.StartsWith(normalizedPartUriString, StringComparison.Ordinal) && text2.Length > normalizedPartUriString.Length && text2[normalizedPartUriString.Length] == PackUriHelper.ForwardSlashChar))
    {
        this._partList.Remove(partUri);
        throw new InvalidOperationException(SR.Get("PartNamePrefixExists"));
    }
}

代码在断言时失败,因为这是调用FailFast

的唯一方法
internal static void Assert(bool condition, string invariantMessage)
{
    if (!condition)
    {
        Invariant.FailFast(invariantMessage, null);
    }
}

现在问题仍然是为什么在PartList数组中找不到包。 WPF为您填写了一些内容。您是否可以通过互联网地址或网络共享从您的XAML引用某些资源,如果您的Windows嵌入式网络子系统还没有准备就可能会失败?
