【Unity】Unity打包后如何隐藏任务栏，窗口置顶，隐藏标题。

using System.Runtime.InteropServices;
//control the task bar hide or show
//liuyanlei
public class ToolControlTaskBar
{
    [DllImport("user32.dll")]   //这里是引入 user32.dll 库， 这个库是windows系统自带的。
    public static extern int ShowWindow(int hwnd, int nCmdShow); //这是显示任务栏
    [DllImport("user32.dll")] 
    public static extern int FindWindow(string lpClassName, string lpWindowName); //这是隐藏任务栏

    private const int SW_HIDE = 0;  //hied task bar
    private const int SW_RESTORE = 9;//show task bar
    // Use this for initialization
    

    /// 

    /// show TaskBar
    /// 
    public static void ShowTaskBar()
    {
        ShowWindow(FindWindow("Shell_TrayWnd", null), SW_RESTORE);
    }
    /// 

    /// Hide TaskBar
    /// 
    public static void HideTaskBar()
    {
        ShowWindow(FindWindow("Shell_TrayWnd", null), SW_HIDE);
    }
}

将这个脚本加入Unity工程，然后，只需要调用 ShowTaskBar（），和HideTaskBar（） 就可以控制任务栏显示和隐藏了。

 

然后再说说游戏窗口的置顶，和游戏的窗口隐藏。
