C# 为什么我的程序在执行`Print（）`函数后立即崩溃？

我已经跨过它，仍然找不到它崩溃的明显原因。在我完成

Print（）

函数的末尾之前，一切都正常。整个程序看起来像

已经尝试了很长时间，但无法找出哪里出了问题

它没有崩溃，控制台窗口在代码完成后被终止。请在catch block后调用console.Read（）

同意，看起来一切正常。它打印出您的所有字符串并以代码0退出。请尝试重新读取输出。最后一行：“程序'[2556]StringSet.vshost.exe'已退出，代码为0（0x0）。”。过去100年左右的退出代码0（好的，没有那么多）意味着没有错误。因此，这个计划已经存在了。控制台程序在代码结束时执行此操作。
