优雅地处理 .NET Core 中的损坏状态异常 [英] Gracefully handling corrupted state exceptions in .NET Core

问题描述

我基本上有一个重复的问题，但对于 .NET Core.

I have basically a duplicate question but for .NET Core.

我有核心控制台应用程序:

I have Core console app:

class Program
{
    static void DoSomeAccessViolation()
    {
        // if you have any questions about why this throws,
        // the answer is "42", of course

        var ptr = new IntPtr(42);
        Marshal.StructureToPtr(42, ptr, true);
    }

    [SecurityCritical]
    [HandleProcessCorruptedStateExceptions]
    static void Main(string[] args)
    {
        try
        {
            DoSomeAccessViolation();
        }
        catch (Exception ex)
        {
            Console.Error.WriteLine(ex);
        }
    }
}

我尝试添加一个 Settings.setting 文件

I've tried to add a Settings.setting file

<SettingsFile xmlns="http://schemas.microsoft.com/VisualStudio/2004/01/settings" CurrentProfile="(Default)" GeneratedClassNamespace="ConsoleApp2" GeneratedClassName="Settings1">
  <Profiles />
  <Settings>
    <Setting Name="legacyCorruptedStateExceptionsPolicy" Type="System.Boolean" Scope="Application">
      <Value Profile="(Default)">True</Value>
    </Setting>
  </Settings>
</SettingsFile>

我尝试根据 文档:

C:>set COMPlus_legacyCorruptedStateExceptionsPolicy=1
C:>dotnet run

或

C:>set COMPlus_legacyCorruptedStateExceptionsPolicy=true
C:>dotnet run

(在 Windows 上).但没有任何效果，应用程序总是在不打印异常的情况下严重崩溃.

(on Windows). But nothing works, the app always crashes hard without printing the exception.

推荐答案

我一直在按时间顺序挖掘这个主题的一些背景...

我目前是 SOL.必须创建各种非托管包装器来捕获外部 CSE.

I'm SOL currently. Have to create an unmanaged wrapper of sorts to catch external CSEs.

你可以试试更多选项，特别是 FailFastOnCorruptedStateException 与 legacyCorruptedStateExceptionsPolicy 相结合.

You can try a few more options, specifically FailFastOnCorruptedStateException combined with legacyCorruptedStateExceptionsPolicy.
