debugging崩溃而不会引发AppDomain.UnhandledException的exe文件

我有一个exe在Visual Studio中正常工作。当我将它部署到Windows Server时，它会崩溃 – 即使我试图捕获它的未处理的exception，如下面的代码所示。代码DOES在VS中捕获未处理的exception（即在msg框中显示exception对象）。当代码在服务器上崩溃时，它为我提供了在Visual Studio中“debugging”代码的机会，提供下面显示的读数。

为什么我的exception处理程序不显示消息框？
我如何解读这个崩溃读数？

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：

围绕整个程序的try-catch块捕获所有的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遇到任何问题，那么肯定也会在创建日志文件时报告错误。所以你也没有看到错误。至少还要使用Console.WriteLine（）。

这样的问题的一个典型的原因是您创建文件，而不指定文件的完整路径名称。所以你会严重依赖于正确设置程序的默认目录。从桌面启动时从命令行提示符启动时，这将不一样。而且要小心，没有UAC标高的地方你可以写信的地方很少。总是指定文件的完整路径名，使用Environment.GetFolderPath（）来查找可写目录。
