Unity 发布的PC 端程序怎么实现隐藏任务栏，窗口置顶，隐藏标题? 如果单单使用Unity的api 能否实现我不知道，反正查了很多但是都没查到。那么，我想到了借助windows的编程库来实现，反正Unity 是可以调用 c++ 和C# 库函数的。

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。

这个脚本挂到场景照相机上就好了，其实总结起来就是，通过windows 编程的api 找到当前窗口的名字， IntPtr hWnd = FindWindow(null, "udpeffect"); //udpeffect 这个是我unity 打包发布后的窗口名字。这里注意设置。只有找到这个窗口，才会把这个窗口置顶。然后设置无边框。这个脚本在编辑器下是没有效果的，因为只有打包后才可以，找到这个窗口。

好了，我这里只是把一些功能集中，其实这些都可以在widnows 编程里面找到。
