由于InteropServices.SEHException中出现了未处理的异常，该流程已终止。

Question

我搜索过，但我找不到任何有关此错误或如何解决此错误的具体信息。

我们在代码的不同位置和不同电脑上经常遇到此错误。

以下是错误信息：

这是两台电脑发送的第二条消息：

这些来自两台不同电脑，位于两个不同的办公室。我该如何进行故障排除？我们有一个包装器，'应该'捕获应用程序中所有未处理的错误，并且目前没有漏掉任何错误。这让我更加困惑，因为它是如何绕过这个捕获所有的错误的。

有什么建议吗？

我不能告诉你太多关于这个问题，但如果我理解正确的话，这可能是由于在SEH例程中发生了内部异常。内部异常是指在SEH例程正在处理先前捕获的异常时发生的异常。尽管实现了SEH例程，但内部异常可能是这种错误消息的原因。例如，如果抛出了FileNotFoundException并被SEH例程成功接收，但在处理过程中出现了IOException，就会出现这种情况。可以在此处找到简要说明：http://msdn.microsoft.com/en-us/library/vstudio/0yd65esw.aspx。 - devavx

Answer 1

出错应用程序路径: I:\RPG\vblib\propane.exe

这是异常详情中最重要的提示。异常代码（0xc0000006）是一个非常低级的Windows错误，STATUS_IN_PAGE_ERROR，“由于I/O错误未将所需数据放入内存”。当操作系统需要从分页文件或内存映射文件检索数据时，如果读取文件失败，则会发生此错误。

相符的事实是，磁盘驱动器字母很不寻常，通常用于映射到网络共享。.NET程序集作为内存映射文件加载，其中的元数据和MSIL会动态从文件中加载以生成程序集方法的代码。

换句话说，客户使用的网络不够可靠。当网络连接断开时，程序崩溃。除了强烈建议客户使用您应用程序的本地安装外，当然没有其他办法。ClickOnce适用于此。

Answer 2

SEHException类处理从非托管代码抛出的SEH错误，但这些错误尚未映射到另一个.NET Framework异常。因此，您应该检查本机代码而不是C#代码。
