最近在学习 C#，同时调试一些 Appium 的封装代码，我使用的是建立一个 Console Application 来调用我封装好的 DLL 文件。其中有一个是网上找的 dll 工具，用来识别图形验证码的 Reconizer.dll，这个 dll 其他人调用的时候没问题，到我这里一调用，就会 Console 直接闪退，完全来不及看报的是什么错误。请问 C# 高手们，对于这种情况我该如何去定位 Console 闪退的原因捏？有没有什么好的方法推荐下 T_T

我用 Try Catch 也不行……STO

Console 闪退关闭以后，控制台的日志如下：

解决办法：
我用 cmd 调用编译好的.exe 文件，这样子 Console 退出以后我也可以看到它的信息啦！哥是不是很聪明^{_______^}
终于看到了错误，好坑爹~：
