Question

**编辑：当我在MinimizePlayer（）方法中放置一个断点并逐步执行它时，它最小化了wmplayer进程。但它并非没有踩过。我不知道为什么。 **

我的Linux机器上有一个类似的脚本，我自动执行了每次启动时使用的一些任务。我能够启动Rhythmbox，开始播放我的播放列表，并最小化该过程。

好吧，我在新的Windows 10计算机上尝试了同样的事情，而且我不知道如何从我的脚本中最小化wmplayer.exe进程。

这是我到目前为止所拥有的。它工作正常，我只想让wmplayer最小化：

using System;
using System.Diagnostics;
using System.Threading;
using System.Runtime.InteropServices;


namespace Playlist
{
    class Program
    {

        [DllImport("user32.dll")]
        private static extern bool ShowWindow(IntPtr hWnd, WindowShowStyle nCmdShow);

        private enum WindowShowStyle:uint
        {
            Hide = 0,
            ShowMinimized = 2, 
            Minimize = 6
        }

        static void Main(string[] args)
        {
            Run();
        }


        public static void Run()
        {

            String username = Environment.UserName;
            username = char.ToUpper(username[0]) + username.Substring(1);
            Console.WriteLine("Hello " + username);
            Thread.Sleep(2000);
            Console.WriteLine("Opening Playlist...");
            Thread.Sleep(2000);

            Process.Start("wmplayer.exe", "C:\\Users\\" + username + "\\Music\\A_ChillstepMix.mp3");
            //Thread.Sleep(2000);
            //Console.WriteLine("Opening your IDE...");
            //Thread.Sleep(2000);
            //Process.Start("C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\Common7\\IDE\\devenv.exe");
            //Thread.Sleep(2000);
            MinimizePlayer();
            Thread.Sleep(2000);
            Console.WriteLine("Goodbye...");
            Thread.Sleep(2000);                
            System.Environment.Exit(0);   

        }       
        public static void MinimizePlayer()
        {
            Process[] ps = Process.GetProcesses();
            foreach(Process p in ps)
            {
                if(p.ProcessName.Contains("wmplayer"))
                {
                    IntPtr h = p.MainWindowHandle;

                    ShowWindow(h, WindowShowStyle.Minimize);
                }
            }
        }
    }
}

如果使用ProcessStartInfo对象，则可以指定要启动的进程的WindowStyle：

var psi = new System.Diagnostics.ProcessStartInfo();
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized;
psi.FileName = "wmplayer.exe";
System.Diagnostics.Process.Start(psi);

好的，我明白了。我需要在MinimizePlayer（）方法之前添加Thread.Sleep（）。工作代码如下（我在调试时注释掉了Visual Studio的内容以加快速度）：

using System;
using System.Diagnostics;
using System.Threading;
using System.Runtime.InteropServices;


namespace Playlist
{
    class Program
    {

        [DllImport("user32.dll")]
        private static extern bool ShowWindow(IntPtr hWnd, WindowShowStyle nCmdShow);

        private enum WindowShowStyle:uint
        {
            Hide = 0,
            ShowMinimized = 2, 
            Minimize = 6
        }

        static void Main(string[] args)
        {
            Run();
        }


        public static void Run()
        {

            String username = Environment.UserName;
            username = char.ToUpper(username[0]) + username.Substring(1);
            Console.WriteLine("Hello " + username);
            Thread.Sleep(2000);
            Console.WriteLine("Opening Playlist...");
            Thread.Sleep(2000);

            Process.Start("wmplayer.exe", "C:\\Users\\" + username + "\\Music\\A_ChillstepMix.mp3");
            //Thread.Sleep(2000);
            //Console.WriteLine("Opening your IDE...");
            //Thread.Sleep(2000);
            //Process.Start("C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\Common7\\IDE\\devenv.exe");
            Thread.Sleep(2000);
            Console.WriteLine("Minimizing Player...");
            Thread.Sleep(2000);
            MinimizePlayer();
            Thread.Sleep(2000);
            Console.WriteLine("Goodbye...");
            Thread.Sleep(5000);            
            System.Environment.Exit(0);   

        }       
        public static void MinimizePlayer()
        {
            Process[] ps = Process.GetProcesses();
            foreach(Process p in ps)
            {
                if(p.ProcessName.Contains("wmplayer"))
                {
                    IntPtr h = p.MainWindowHandle;

                    ShowWindow(h, WindowShowStyle.Minimize);
                }
            }
        }
    }
}

最小化窗口功能仅在步进调试器（C＃ - 控制台）时有效
