推荐答案

没有办法通过将任何设备连接到并行端口来自动运行exe文件 - 它只是不能那样工作。

你必须有一个程序坐在PC​​上监控并行端口并在被告知时执行程序。



见这里： I / O端口编程（并行端口）使用VB.NET读/写+监控系统 [ ^ ]



和这里：进程类 [ ^ ]

There is no way to automatically run an exe file by just connecting any device to a parallel port - it just doesn''t work like that.
You would have to have a program sitting on the PC monitoring the parallel port and executing the program when told to.

See here: I/O Ports Programming (Parallel port) Reading / Writing + Surveillance System using VB.NET[^]

and here: Process Class[^]
