调试一个在不引发 AppDomain.UnhandledException 的情况下崩溃的 exe

Question

我有一个可以在 Visual Studio 中正常运行的 exe。当我将它部署到 Windows Server 时，它崩溃了——即使我试图捕获它未处理的异常，如下面的代码所示。代码 DOES 在 VS 中按预期捕获未处理的异常（即，它在 msg 框中显示异常对象）。当代码在服务器上崩溃时，它让我有机会在 Visual Studio 中“调试”代码，提供如下所示的读数。

1. 为什么我的异常处理程序没有显示消息框？
2. 如何解释这个崩溃读数？

Sub Main(ByVal args() As String)

    AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf errorReporter

    Dim myProcess As AutomatedProcessVB = New AutomatedProcessVB("Laphie")

    myProcess.run()

End Sub

Private Sub errorReporter(sender As Object, e As System.UnhandledExceptionEventArgs)
    MsgBox(e.ExceptionObject.ToString)
    Environment.Exit(3)
End Sub

这是程序崩溃时的输出：

包围整个程序的 try-catch 块捕获所有错误并将它们写入文件

这是一个令人不安的选择。如果程序在创建文件时有任何问题，那么它肯定也会在创建日志文件以报告错误时遇到问题。所以你也看不到错误。至少也要使用 Console.WriteLine()。

此类问题的典型原因是您在创建文件时未指定文件的完整路径名。因此，您将严重依赖正确设置程序的默认目录。从桌面启动与从命令行提示启动时不同。请注意，如果没有 UAC 提升，您可以写入的地方很少。始终指定文件的完整路径名，使用 Environment.GetFolderPath() 查找可写目录。
