使用系统自带的googlechrome浏览器最大化打开页面关闭，判断是否安装

1,。关闭

载入系统api

[DllImport("user32.dll")]
        private static extern bool EnumWindows(EnumWindowsProc enumProc, IntPtr lParam);

        [DllImport("user32.dll", CharSet = CharSet.Unicode, SetLastError = true)]
        private static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount);

        [DllImport("user32.dll", CharSet = CharSet.Unicode)]
        private static extern int GetWindowTextLength(IntPtr hWnd);

        [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
        private static extern int GetClassName(IntPtr hWnd, StringBuilder lpClassName, int nMaxCount);

        [DllImport("user32.dll", ExactSpelling = true, CharSet = CharSet.Auto)]
        private static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

        public delegate bool EnumWindowsProc(IntPtr hWnd, IntPtr lParam);
        [DllImport("user32.dll")]
        public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

        public const int SW_HIDE = 0;
        public const int SW_SHOWNORMAL = 1;
        public const int SW_SHOWMINIMIZED = 2;
        public const int SW_SHOWMAXIMIZED = 3;

找到线程关掉它。

 var processes = Process.GetProcessesByName("chrome");
            //获取程序名的所有进程
            if (processes.Length > 0)
            {
                foreach (var app in processes)
                {
                    if (!app.HasExited)
                    {
                        app.Kill();//关闭进程
                    }
                }
            }

2，打开。

this.TransparencyKey = Color.Red;//背景色为红色后显示为空白。
            this.BackColor = Color.Red;
            string url = string.IsNullOrWhiteSpace( ConfigurationManager.AppSettings["Url"])?"http://localhost/":  ConfigurationManager.AppSettings["Url"] ;
            this.Location = new Point(Screen.PrimaryScreen.WorkingArea.Width-100,8);//当前窗体位置
            this.Opacity =10; 
            System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.FileName ="chrome.exe";// Environment.CurrentDirectory   "\\Chrome\\App\\chrome.exe";
            startInfo.Arguments = $" --kiosk \"{url}\"";
            startInfo.UseShellExecute = true;
            startInfo.RedirectStandardInput = false;
            startInfo.RedirectStandardOutput = false;
            startInfo.RedirectStandardError = false;
            startInfo.CreateNoWindow = true;

            System.Diagnostics.Process.Start(startInfo);

3.获取是否系统安装了浏览器

 if (!Common.SystemGet.RegistryHelper.checkSoftIsSetupLM("Chrome")&& !Common.SystemGet.RegistryHelper.checkSoftIsSetupUser("Chrome"))
            {
                MessageBox.Show("请安装谷歌chrome浏览器。", "系统提示：", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
