您想要做的事不可能是理智的。还有一个类似的问题,请看一下答案。
然后,还有一种由杰弗里·奈特(Jeffrey Knight)编写的疯狂方法(可在此处下载站点-
进行备份):
问题:如何创建可以在GUI(Windows)模式或命令行/控制台模式下运行的应用程序?
从表面上看,这似乎很容易:创建一个Console应用程序,向其中添加Windows窗体,然后启动并运行。但是,有一个问题:
问题:如果以GUI模式运行,最终将在后台隐藏一个窗口和一个讨厌的控制台,而您将无法隐藏它。
人们似乎想要的是一个真正的两栖应用程序,它可以在任何一种模式下都能平稳运行。
如果将其分解,实际上这里有四个用例:
User starts application from existing cmd window, and runs in GUI modeUser double clicks to start application, and runs in GUI modeUser starts application from existing cmd window, and runs in commandmode
User double clicks to start application, and runs in command mode.我正在发布代码来执行此操作,但需要注意。
实际上,我认为这种方法会使您遇到很多麻烦,而不是值得的。例如,您将必须具有两个不同的UI-一个用于GUI,另一个用于命令/
shell。您将必须构建一些奇怪的中央逻辑引擎,该引擎从GUI与命令行进行抽象,这只会变得很奇怪。如果是我,我会退后一步,思考一下如何在实践中使用它,以及是否值得进行这种模式切换。因此,除非有特殊情况需要,否则我不会自己使用该代码,因为一旦遇到需要API调用才能完成某件事的情况,我就会停下来问自己“我是否使事情过于复杂了?
