在Visual Studio中重新打开项目后，控制台窗口不会出现

Question

我在C＃编写了一个程序，用于将二进制字符串转换为其他数字编号系统和int，它工作得非常好，然后保存并关闭它。当我重新打开它时，我得到了这个例外：

$exception {"Cannot read keys when either application does not have a console or when console input has been redirected from a file. Try Console.Read."} System.InvalidOperationException

这是因为我在程序结束时有Console.ReadKey();。但是当我删除它时，控制台窗口根本不会出现，即使程序要求用户输入，过程也会结束。以下是供参考的程序：
