How to determine whether code is getting executed in a console app or in a windows service

Question

如何确定代码是在控制台应用程序还是Windows服务中执行？

Answer 1

Whilst it's not console specific (ie this will return true when running as a winforms app as well) I've used the following

if (Environment.UserInteractive)
{
    Console.WriteLine("Hi I'm being ran as a console app");
}
