如何确定一个控制台应用程序是如何启动的？ [英] How can you determine how a console application was launched?

问题描述

我怎么能告诉用户是否通过推出我的控制台应用程序双击EXE（或快捷方式），或者是否他们已经有一个命令行窗口打开，该会话中执行我的控制台应用程序？

How can I tell whether the user launched my console application by double-clicking the EXE (or a shortcut), or whether they already had a command line window open and executed my console app within that session?

推荐答案

坚持这一静态字段在计划类，以确保它的任何输出前运行：

Stick this static field in your "Program" class to ensure it runs before any output:

static bool StartedFromGui = 
         !Console.IsOutputRedirected
      && !Console.IsInputRedirected
      && !Console.IsErrorRedirected
      && Environment.UserInteractive
      && Environment.CurrentDirectory == System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location)
      && Console.CursorTop == 0 && Console.CursorLeft == 0
      && Console.Title == Environment.GetCommandLineArgs()[0]
      && Environment.GetCommandLineArgs()[0] == System.Reflection.Assembly.GetEntryAssembly().Location;

这是一个有点矫枉过正/偏执，而是拿起从资源管理器正在启动，而不是应对像 CLS和放大器;＆安培; APP.EXE （通过检查的完整路径），或者甚至 CLS和放大器;＆安培; F：\ ULL \路径\为\ APP.EXE（通过看标题）

This is a little bit overkill/paranoid, but picks up being started from Explorer while not responding to things like cls && app.exe (by checking for the full path) or even cls && "f:\ull\path\to\app.exe" (by looking at the title).
