.net - 如何处理 System.AccessViolationException？

Question

我在我的程序中使用了一个外部 C 库，用 C++/CLI 和 .NET 框架 4 编码。有时库崩溃，我收到消息:

Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory.

所以我尝试用 try/catch 块来处理它:

try
{
  Init(); //< lib call which sometimes crashes
}
catch (Exception^ e)
{
  // handle the error
}

但异常仍未被捕获:我的程序在进入 catch 块之前就崩溃了。

如何处理此异常以防止我的程序崩溃？

为清楚起见，我复制/粘贴 the answer在评论中给出 Flot2011这里:

There are a few ways to get around this:

• Recompile as a .NET 3.5 assembly and run it in .NET 4.0.
• Add a line to your application's config file under the configuration/runtime element: <legacyCorruptedStateExceptionsPolicy enabled="true|false"/>
• Decorate the methods you want to catch these exceptions in with the HandleProcessCorruptedStateExceptions attribute. See this article for details.
