真正最小化另一个应用程序

Question

I just want to do real minimized, all public codes are not minimizing in right way! It just minimize it as shown, but not minimize like if I click on Minimize button. How did I know that? Or what benefit will I get from that? When I press on minimize button, it reduce from CPU usage! (It's a game anyway.)

My code is :

    [DllImport("User32.Dll", EntryPoint = "PostMessageA", SetLastError = true)]
    public static extern bool PostMessage(IntPtr hWnd, uint msg, IntPtr wParam, IntPtr lParam);

    List<int> ProcIDs = new List<int>();
    private void timer1_Tick(object sender, EventArgs e)
    {
        foreach (Process process in Process.GetProcesses())
        {
            if (process.ProcessName == "League of Legends")
            {
               // MinimizeWindow((IntPtr)hProcess);
                if (!ProcIDs.Contains(process.Id))
                {
                    IntPtr hProcess = GetProcessWindow(process.Id);
                    ProcIDs.Add(process.Id);
                    PostMessage(hProcess, WM_SYSCOMMAND, (IntPtr)SC_MINIMIZE, IntPtr.Zero);
                }
            }
        }
}
    const int WM_SYSCOMMAND = 274;
    const int SC_MINIMIZE = 0xF020;

I also tried other methods and it does the same, just minimize as show, but not real minimize! :)

You can try this

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

with window style as ShowMinimized = 2,
