当我使用 Web 应用程序时，应用程序会将我注销。我认为这可能是 IIS 回收。
事件查看器消息:

最佳答案
我解决了这个问题。 解决步骤:
- 首先我打开 ControlPanel> ActionCenter> 问题报告
- 我看到了问题列表。还有我的 IIS 崩溃问题。
- 我输入了项目详细信息并将其保存为转储。
- 我下载了 Windbg，然后用它打开了这个转储。
- 然后输入命令
!analyze -v
Windbg 分析并显示如下文本:

所以我将这段代码添加到解密方法中:if (String.IsNullOrEmpty(value)) return 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。
