我试图让我的WinForm基于C＃也与命令行进行合作，但我有困难得到它发挥不错。例如，我有这样的code：

I'm trying to get my WinForm based C# to cooperate with the commandline too, but I'm having difficulty getting it to play nice. For example, I have this code:

    [STAThread]
    static void Main(string[] args) {
        foreach (string s in args) {
            System.Windows.Forms.MessageBox.Show(s);
            Console.WriteLine("String: " + s);
        }

        Mutex appSingleton = new System.Threading.Mutex(false, "WinSyncSingalInstanceMutx");
        if (appSingleton.WaitOne(0, false)) {
            try {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

                //start logger
                Logger.singleton.makeOpen(true);
                Application.Run(new MainForm(false));
            } catch (Exception) {
            } finally {
                appSingleton.Close();
                Logger.singleton.makeOpen(false); 
            }
        } else {
            System.Windows.Forms.MessageBox.Show("Sorry, only one instance of WinSync can be ran at once.");
        }
    }
}

这应该写与Console.WriteLine命令控制台，但我什么也看不到，只有在MessageBox显示出来。

It should write to the console with the Console.WriteLine, but I see nothing, only the MessageBox shows up.

我是什么做错了吗？

推荐答案

尝试AttachConsole（-1）重定向Console.Out，为我工作：

Try AttachConsole(-1) to redirect Console.Out, worked for me:

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace PEFixer
{
    static class Program
    {
        [DllImport("kernel32.dll")]
        private static extern bool AttachConsole(int dwProcessId);

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static int Main(string[] args)
        {
            if (args.Length > 0)
            {
                AttachConsole(-1);
                return Form1.doTransformCmdLine(args);
            }
            else
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
            }
            return 0;
        }
    }
}
