如何创建一个 C# 应用程序来决定自己是显示为控制台还是窗口应用程序? [英] How do I create a C# app that decides itself whether to show as a console or windowed app?

问题描述

有没有办法启动具有以下功能的 C# 应用程序?

Is there a way to launch a C# application with the following features?

1. 它通过命令行参数确定它是窗口应用程序还是控制台应用程序
2. 当它被要求窗口化时不显示控制台，当它从控制台运行时不显示 GUI 窗口.

例如，

myapp.exe /help

会输出到您使用的控制台上的 stdout，但

would output to stdout on the console you used, but

myapp.exe

本身会启动我的 Winforms 或 WPF 用户界面.

到目前为止，我所知道的最好的答案是使用两个独立的 exe 并使用 IPC，但这感觉真的很糟糕.

by itself would launch my Winforms or WPF user interface.

The best answers I know of so far involve having two separate exe and use IPC, but that feels really hacky.

为了获得上述示例中描述的行为，我有哪些选择和权衡取舍?我也乐于接受特定于 Winform 或 WPF 的想法.

What options do I have and trade-offs can I make to get the behavior described in the example above? I'm open to ideas that are Winform-specific or WPF-specific, too.

推荐答案

使应用成为常规的 Windows 应用，并在需要时即时创建控制台.

Make the app a regular windows app, and create a console on the fly if needed.

using System;
using System.Windows.Forms;

namespace WindowsApplication1 {
  static class Program {
    [STAThread]
    static void Main(string[] args) {
      if (args.Length > 0) {
        // Command line given, display console
        if ( !AttachConsole(-1) ) { // Attach to an parent process console
           AllocConsole(); // Alloc a new console
        }

        ConsoleMain(args);
      }
      else {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
      }
    }
    private static void ConsoleMain(string[] args) {
      Console.WriteLine("Command line = {0}", Environment.CommandLine);
      for (int ix = 0; ix < args.Length; ++ix)
        Console.WriteLine("Argument{0} = {1}", ix + 1, args[ix]);
      Console.ReadLine();
    }

    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    private static extern bool AllocConsole();

    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    private static extern bool AttachConsole(int pid);

  }
}
