我有一个在 Visual Studio 中正常工作的 exe。当我将它部署到 Windows Server 时，它会崩溃——即使我试图捕获它未处理的异常，如下面的代码所示。代码确实按照 VS 中的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不显示消息框？
  2. 我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。
