Question

当我使用Web应用程序时，应用程序会将我注销。我认为它可能是一个IIS回收。

EventViewer消息：

我解决了这个问题。解决方案步骤：

首先我打开ControlPanel＆gt; ActionCenter＆GT;问题报告
我看到了一系列问题。和我的IIS崩溃问题。
我输入了项目详细信息并保存为转储。
我下载了Windbg然后用它打开这个转储。
并输入命令!analyze -v

Windbg分析并显示如下文字：

所以我将此代码添加到Decrypt方法： if（String.IsNullOrEmpty（value））返回String.Empty;

public static string Decrypt(string value)
    {
        SymmetricAlgorithm algorithm = SymmetricAlgorithm.Create();
        ICryptoTransform decryptor = algorithm.CreateDecryptor(EncryptionKey, EncryptionVector);

        // I control value
        **if (String.IsNullOrEmpty(value))
            return String.Empty;**

        byte[] encryptedBytes = Convert.FromBase64String(value);
        MemoryStream memoryStream = new MemoryStream(encryptedBytes);
        CryptoStream cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);
        ...
    }

问题解决了。

Answer 2

我知道我迟到了，但我只是用WinDbg调试了类似的问题。我终于找到了问题的原因。

这是微软报道的一个错误： http://connect.microsoft.com/VisualStudio/feedback/details/330926/cryptostream-flushfinalblock-fatal-on-64-bit-os-if-bytearray-is-null

我只是将其添加到讨论中，作为搜索网络的其他人的主角。

Answer 3

Tess Ferrandez有一些很棒的教程和信息，介绍如何使用DebugDiag和WinDbg来确定发生这种情况的原因：

If it is broken, fix it you should

还有一个实验室可以引导您分析工作进程崩溃：

.NET Debugging Demos Lab 5: Crash

.NET Debugging Demos Lab 2: Crash - Review

Answer 4

我遇到了完全相同的症状，真正的原因是我不小心创建了一个无限递归，这反过来导致了堆栈溢出。请注意，您需要在纠正错误后重新启动应用程序池。

Answer 5

ASP.NET辅助进程因访问冲突而崩溃。这通常是取消引用NULL或无效指针的结果。尝试在C＃中访问空引用通常会生成ASP.NET能够捕获的托管异常，我假设您的Web应用程序正在使用COM互操作或正在调用崩溃的非托管（C ++）代码。

不幸的是，这与我们从上面的信息告诉你的情况差不多。您需要调试流程以了解崩溃的确切原因。

IIS问题，Web应用程序
