Question

我正在尝试跟踪从生产启动时导致我的应用程序启动时崩溃的原因。从Visual Studio中的调试启动时，此C＃/。NET Windows应用程序启动没有任何问题，结果如预期。同一应用程序的早期版本也已在其他客户端计算机上部署并运行从Windows Error Reporting and CLR integration中的解释中读取，似乎我的问题来自于汇编ExcelInterop中的方法。

P10 :

尝试找到我使用windbg.exe菜单启动应用程序的错误 - ＆gt;文件 - ＆gt;打开可执行文件（我第一次使用windbg），但控制台显示符号搜索路径无效。根据{{3}}，我使用以下命令序列恢复了符号路径：

!sym noisy    
.symfix
.reload -f

第一次试用加载SOS导致“无法找到模块mscorwks”错误，Debugging .net using SOS解决了这部分问题：

sxe ld:mscorlib
g
.loadby sos mscorwks
!token2ee ExcelInterop 06000013

我预计最后一个命令将确定与事件报告中的数字相关联的methodDesc，但没有返回任何内容。

我现在感到陷入了一种迷宫。还有什么办法可以找到导致崩溃的原因？

Answer 1

您可以设置sxe clr，这会在第一次出现异常时中断。然后执行!clrstack会给出调用堆栈。

Methoddsec 06000013可能因JIT而异，所以你可能会看到不会给你带来结果的指针。

启动时应用程序崩溃，无异常引发
